Selected AbstractsRelationship between smoking status and periodontal conditions: findings from national databases in JapanJOURNAL OF PERIODONTAL RESEARCH, Issue 6 2006M. Ojima Background and Objective:, The association between cigarette smoking and periodontitis was examined employing two nationally representative samples of adults in Japan. Material and Methods:, Data were derived from the Survey of Dental Diseases (SDD) and the National Nutrition Survey (NNS) in 1999. In the SDD, periodontal conditions were evaluated by calibrated dentists utilizing the Community Periodontal Index (CPI), whereas in the NNS, participants were interviewed on the basis of smoking status by enumerators. Among 6805 records electronically linked via a household identification code, 4828 records of individuals aged 20 yr or older were analyzed. Results:, The prevalence of periodontal disease varied significantly by smoking status (p < 0.0001): 39.3%, 49.5% and 47.3% (CPI , 3), and 7.9%, 11.7% and 12.4% (a more severe form of periodontitis, CPI = 4), for nonsmokers, former smokers and current smokers, respectively. In adults aged ,,40 yr (n = 3493), logistic regression models revealed greater probabilities (approximately 1.4 times higher) of periodontitis [CPI , 3, odds ratio = 1.38 (1.12,1.71), p = 0.0024] and a more severe form of periodontitis [odds ratio = 1.40 (1.04,1.89), p = 0.0288] in current smokers compared with nonsmokers, following adjustment for possible confounding factors. Conclusion:, Based on the findings of this study and other numerous reports, cigarette smoking leads to deterioration of periodontal conditions in Japanese adults.

No extensive clinical studies in donkeys have investigated the potential relationship between different dental disorders, or between dental disease and systemic disorders. Objectives: To determine possible associations between dental disease and body condition score, weight loss, the need for supplemental feeding and prevalence of colic in donkeys of all ages, and to gain a better understanding of the pathogenesis of dental disease by the determination of associations between different dental disorders. Methods: A prospective cross-sectional analysis of clinical dental examinations of 357 donkeys in The Donkey Sanctuary, Sidmouth was performed. Other epidemiological factors such as estimated age group, body condition score, weight loss, medical history and supplemental feeding were also recorded, and multiple regression analyses were performed to determine possible associations. Results: Donkeys from older age groups were more likely to have dental disease, poor body condition score and suffered previous colic episodes. The presence of dental disease was also significantly associated with weight loss, colic, low body condition score and the need for supplemental feeding. The presence of diastemata, periodontal disease, wave mouth, smooth mouth and step mouth are frequently associated with the presence of other dental disorders. Conclusions: In addition to oral-related pain, dental disease can cause significant systemic disorders and so has increased welfare implications in donkeys. Some dental disorders promote the development of other types of dental abnormalities and thus increase the severity of dental disease in individual animals. Potential significance: Effective treatment of dental disorders slows down the progression of dental disease and decreases the risk of developing some medical disorders such as colic and weight loss that are associated with dental disease. [source] Dental diseases , are these examples of ecological catastrophes?INTERNATIONAL JOURNAL OF DENTAL HYGIENE, Issue 2006PD Marsh First page of article [source] Clinical dental examinations of 357 donkeys in the UK.EQUINE VETERINARY JOURNAL, Issue 4 2009Part 1: Prevalence of dental disorders Summary Reasons for performing study: Dental disorders have a high prevalence in older donkeys and horses, but the nature and pathogenesis of many of these disorders have yet to be established. Objectives: The identification and determination of the prevalence of important dental disorders in different age groups in a large single population of donkeys, to establish a better understanding of the nature and pathogenesis of these disorders. Methods: A prospective cross-sectional study was performed on the donkey population at The Donkey Sanctuary with detailed oral examinations of 357 donkeys within 7 different age groups (age range 2,53 years) recorded. Results: The prevalence of dental disease in all donkeys was 73%, increasing in prevalence from 28% in the youngest to 98% in the oldest age group. There was an increase in prevalence of commonly recognised dental disorders with increasing age, such as: diastemata (3.8% in youngest to 86% in oldest group); missing teeth (0,56%); overgrown teeth (15,86%); worn teeth (8,84%); displaced teeth (0,38%); and periodontal disease (0,28%). Conclusions: There was a significant increase in the prevalence of dental disorders with increasing age with the largest significant increase for most dental disorders occurring in the 15,20 year age group. Potential significance: Most dental disorders significantly increase in prevalence in the 15,20 year age group and, therefore, prophylactic geriatric dental treatment in donkeys should be commenced from age 15 years.

[source] Post mortem survey of dental disorders in 349 donkeys from an aged population (2005,2006).EQUINE VETERINARY JOURNAL, Issue 3 2008Part 1: Prevalence of specific dental disorders Summary Reasons for performing study: Donkey dental disorders are being recognised with increased frequency worldwide and have important welfare implications; however, no detailed investigations of dental disorders in donkeys appear to have been published. Objectives: To determine the prevalence of specified dental disorders in donkeys by performing a prospective post mortem study on donkeys that were subjected to euthanasia or died for other reasons at the Donkey Sanctuary, UK. Methods: Post mortem examinations were performed on 349 donkeys over an 18 month period, 2005,2006. The presence and extent of specified dental disorders were recorded and these data analysed to determine their prevalence and common locations. 45Results: A high prevalence (93%) of disorders was noted in the population with a median age of 31 years. In particular, cheek teeth diastemata (85% prevalence) were very common, often associated with advanced periodontal disease. Other disorders observed included missing teeth (in 55.6% of donkeys), displaced teeth (43%), worn teeth (34%), local overgrowths (15%), focal sharp overgrowths (3%) and dental-related soft tissue injuries (8%). Conclusions and potential relevance: Aged donkeys have a high prevalence of significant dental disease, especially cheek teeth diastemata. These findings highlight the importance of routine dental examinations and prophylactic dental treatments to improve the dental health and welfare of donkeys. [source] Equine dental disease Part 4: a long-term study of 400 cases: apical infections of cheek teethEQUINE VETERINARY JOURNAL, Issue 3 2000P. M. Dixon Summary Of 400 horses referred because of equine dental disease, 162 suffered from primary apical infections of their cheek teeth (CT), including 92 with maxillary CT infections and 70 with mandibular CT infections. Maxillary swellings and sinus tracts were more common (82 and 26% incidence, respectively) with infections of the rostral 3 maxillary CT, than with infections of the caudal 3 maxillary CT(39 and 5% incidence, respectively). Nasal discharge was more commonly present with caudal (95%) than rostral (23%) maxillary CT infections. Mandibular CT apical infections commonly had mandibular swellings (91%) and mandibular sinus tracts (59%) and these infections were closely related to eruption of the affected CT. A variety of treatments, including medical treatment, apical curettage, repulsion and oral extraction of affected teeth were utilised in these cases, with oral extraction appearing to be most satisfactory. Infections of caudal maxillary CT with a secondary paranasal sinusitis were most refractory to treatment, with a complete response to the initial treatment achieved in just 33% of these cases. Most other cases responded fully to their initial treatment. The long-term response to treatment was good in most cases. [source] Reasons for placement and replacement of restorations in student clinics in Manchester and AthensEUROPEAN JOURNAL OF DENTAL EDUCATION, Issue 4 2000V. Deligeorgi Data on reasons for the placement and replacement of restorations provide insight into patterns of clinical practice. This study investigated reasons for the provision of restorations in student clinics at the Universities of Manchester and Athens. Using the methods first described by Mjör, data were collected in relation to all initial and replacement restorations placed in adult patients in the main teaching clinics in the 2 schools over a 3-month period. The principal reason for intervention was recorded, according to approved treatment plans. Data were collected on 2620 restorations, 1431 (55%) of which were placed in Manchester. Primary caries was the main reason for the placement of initial restorations: 82% in Athens and 48% in Manchester (p<0.001). The principal reason for restoration replacement was secondary caries, accounting for 54% in Manchester and 33% in Athens (p<0.001). Other differences between the schools, included the ratio of initial placement to replacement restorations (Manchester 1:1.1; Athens 1:0.6: p<0.01) and significantly more 2-surface class II restorations having been placed in Manchester (p<0.001). Class III and IV restorations predominated in Athens. It is concluded, despite the acknowledged limitations of the methods employed, that the patterns of placement and replacement of restorations and the use of materials differ between the dental schools of Manchester and Athens. The differences are considered to relate more to local patterns of dental disease and patient selection for student clinics than to any differences in teaching philosophy. Subsequent studies of the type reported, despite acknowledged limitations would provide insight into the impact on patient care of the teaching of new materials, techniques and treatment philosophies. [source] Oral disease experience of older adults seeking oral health servicesGERODONTOLOGY, Issue 2 2010Kavita P. Ahluwalia doi:10.1111/j.1741-2358.2009.00311.x Oral disease experience of older adults seeking oral health services Objective:, The objective of this investigation was to describe the dental disease (dental caries and alveolar bone loss) experience in a sample of community-dwelling older adults who regularly utilize dental services in New York City. Background:, Public financing for dental care directed at older adults in the United States is minimal. Improved preventive methods, primarily the use of fluorides, have resulted in declines in tooth loss, and concomitant increase in risk for dental diseases among older adults. While the oral disease burden in institutionalized elderly and those unable to access services is well-documented, the dental care needs of older adults who access dental services are not well documented. Materials and Methods:, Radiographic and record review were used to determine prevalence of dental caries, alveolar bone loss, frequency of service utilization, and medical status in this cross-sectional investigation of a sample of older adults (N = 200) using dental services at Columbia University College of Dental Medicine. Results:, Only 9% of the sample was completely edentulous, the mean DMFT was 19.9 and mean alveolar bone loss was 3.6 mm. Missing and Decayed Teeth accounted for 57.8% and 6.5% of the total caries burden respectively. Missing Teeth and alveolar bone loss increased with increasing age, but there was no increase in Decayed Teeth. Conclusions:, While access to and utilization of dental services may result in improved tooth retention, older adults who use dental services continue to have dental care needs, especially periodontal care needs. [source] Do pre-irradiation dental extractions reduce the risk of osteoradionecrosis of the mandible?HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 6 2007Daniel T. Chang MD Abstract Background. This study was done to determine if pre-radiotherapy (pre-RT) dental extractions reduce the risk of osteoradionecrosis (ORN). Methods. Between 1987 and 2004, 413 patients with oropharyngeal carcinomas were treated with definitive RT at the University of Florida. Dentate patients underwent pretreatment dental evaluation. Teeth in the RT field were usually extracted if thought to have poor long-term prognosis from dental disease. The endpoint was ,grade 2 ORN using a modified staging system. Patients were excluded for local recurrence, additional RT above the clavicles, or head and neck surgery besides neck dissection. Results. ORN rates were as follows: edentulous, <1%; teeth in-field with pre-RT extractions, 15%; and teeth in-field without pre-RT extractions, 9%. Patients with poor in-field teeth and pre-RT extractions had a higher 5-year incidence of ORN than those who did not have pre-RT extractions (16% vs 6%, p = .48). Likewise, for those with in-field teeth in good condition and pre-RT extractions, the 5-year ORN incidence was higher than for those who did not undergo extractions (15% vs 2%, p = .42). Multivariate analysis revealed increased ORN risk with doses of >70 Gy, once-daily fractionation, or brachytherapy. Conclusion. Pre-RT extractions do not appear to reduce the risk of ORN. © 2007 Wiley Periodicals, Inc. Head Neck, 2007 [source] Dental pathology and diet at Apollonia, a Greek colony on the Black SeaINTERNATIONAL JOURNAL OF OSTEOARCHAEOLOGY, Issue 3 2008A. Keenleyside Abstract Dental pathology has the potential to provide insight into the composition of the diet and to reveal dietary differences based on age, sex and social status. Human skeletal remains from the Greek colonial site of Apollonia (5th to 2nd centuries BC) on the Black Sea coast of Bulgaria were analysed for various forms of dental pathology in order to: assess the prevalence of dental disease in the population; compare the dental pathology data from Apollonia with dietary data derived from ancient literary texts and from previous stable isotopic analysis of the colonists' remains; explore variations in dental disease with respect to age and sex; and compare the prevalence of dental pathology in the Apollonians with that of other Greek populations. The composition of the diet, as indicated by the dental pathology data, is consistent with the stable isotopic evidence from Apollonia and with the ancient literary texts, both of which indicate the consumption of a relatively soft, high carbohydrate diet. The higher frequency of dental caries, abscesses, calculus, and antemortem tooth loss in older adults compared with younger ones reflects the age-progressive nature of these conditions. The lack of significant sex differences in caries, abscesses, calculus and tooth loss corresponds with the stable carbon and nitrogen isotopic data derived from bone collagen, which indicate no significant sex differences in the consumption of dietary protein. In contrast, these findings conflict with the ancient literary texts, which refer to distinct dietary differences between males and females, and with the stable carbon isotopic values derived from bone carbonate, which indicate sex differences with respect to the overall diet. Despite the lack of marked sex differences in dental pathology, overall trends point to subtle dietary differences between males and females. A greater degree of tooth wear in males also hints at possible sex differences in the use of the teeth as tools. Copyright © 2007 John Wiley & Sons, Ltd. [source] Validity of single-item parental ratings of child oral healthINTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 6 2008DAVID LOCKER Objective. The aim of this study was to assess the validity of single-item parental ratings of child oral heath. Methods. Data were collected during a study to assess the impacts of dental injury. Clinical examinations of children aged 11,14 years were undertaken that included measures of trauma, decay, treatment needs, and fluorosis. Children with trauma and a group of trauma-free children were followed-up. Parents were mailed a questionnaire along with a questionnaire for the child that contained a short form of the Child Perceptions Questionnaire 11,14 (CPQ11,14). Bivariate analyses examined associations between parents' ratings of their child's oral health, measures of dental disease, clinically defined treatment needs, and scores on the CPQ11,14. Logistic regression was used to see if the associations observed remained after controlling for access to dental care variables. Results. Complete data were collected from 370 children and their parents. Parental ratings showed significant associations with most of the clinical indicators used and CPQ11,14 scores. Similar results were obtained when the data were analysed for subgroups defined by household income and mother's education. These associations remained after controlling for access to dental services. Conclusion. The data suggest that single-item parental ratings of child oral health have adequate construct validity. [source] A preliminary investigation of dental disease in children with HIV infectionINTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 1 2000M. Gelbier Objective. To establish the levels of dental caries and gingivitis in a group of HIV-positive children. Study group. The study group comprised 35 children with the Human Immunodeficiency Virus attending The Great Ormond Street Hospital For Children. Outcome measures. Outcome measures included the number of decayed, missing and filled teeth and surfaces in both the primary and permanent dentitions; plaque and gingivitis scores. Results. The children included 18 boys and 17 girls. They were aged from 6 months to 18 years, with 17 aged 5 years or less and 15 aged 6 years or older. Twenty-four of the 35 children had some caries experience. The mean dmft was 4·4 and for those with permanent teeth the mean DMFT was 0·7. Mean plaque and gingivitis scores were 16·7 and 5·1 for plaque and gingivitis adjacent to primary teeth and 8·0 and 5·7 for that related to permanent teeth. Conclusions. There is a significant treatment need for children with HIV. [source] Enzyme Replacement Therapy for Murine Hypophosphatasia,JOURNAL OF BONE AND MINERAL RESEARCH, Issue 6 2008José Luis Millán PhD Abstract Introduction: Hypophosphatasia (HPP) is the inborn error of metabolism that features rickets or osteomalacia caused by loss-of-function mutation(s) within the gene that encodes the tissue-nonspecific isozyme of alkaline phosphatase (TNALP). Consequently, natural substrates for this ectoenzyme accumulate extracellulary including inorganic pyrophosphate (PPi), an inhibitor of mineralization, and pyridoxal 5,-phosphate (PLP), a co-factor form of vitamin B6. Babies with the infantile form of HPP often die with severe rickets and sometimes hypercalcemia and vitamin B6 -dependent seizures. There is no established medical treatment. Materials and Methods: Human TNALP was bioengineered with the C terminus extended by the Fc region of human IgG for one-step purification and a deca-aspartate sequence (D10) for targeting to mineralizing tissue (sALP-FcD10). TNALP-null mice (Akp2,/,), an excellent model for infantile HPP, were treated from birth using sALP-FcD10. Short-term and long-term efficacy studies consisted of once daily subcutaneous injections of 1, 2, or 8.2 mg/kg sALP-FcD10 for 15, 19, and 15 or 52 days, respectively. We assessed survival and growth rates, circulating levels of sALP-FcD10 activity, calcium, PPi, and pyridoxal, as well as skeletal and dental manifestations using radiography, ,CT, and histomorphometry. Results:Akp2,/, mice receiving high-dose sALP-FcD10 grew normally and appeared well without skeletal or dental disease or epilepsy. Plasma calcium, PPi, and pyridoxal concentrations remained in their normal ranges. We found no evidence of significant skeletal or dental disease. Conclusions: Enzyme replacement using a bone-targeted, recombinant form of human TNALP prevents infantile HPP in Akp2,/, mice. [source] Association between level of education and oral health status in 35-, 50-, 65- and 75-year-oldsJOURNAL OF CLINICAL PERIODONTOLOGY, Issue 8 2003J. Paulander Abstract Aim: The aim of the present study was to evaluate the association between educational level and dental disease, treatment needs and oral hygiene habits. Material and methods: Randomized samples of 35-, 50-, 65- and 75-year-olds, classified according to the educational level: [low (LE): elementary school or higher (HE)], were identified. In 1091 subjects, a number of characteristics such as (i) number of teeth, (ii) periodontal attachment levels (PAL), (iii) caries and (iv) occlusal function were recorded. Educational level, oral hygiene and dietary habits were self-reported. Non-parametric variables were analyzed by ,2, Mann,Whitney U,Wilcoxon's rank sum tests, and parametric variables by Student's t -test (level of significance 95%). A two-way anova was performed on decayed, missing and filled surfaces to investigate the interaction between age and educational level. All statistical procedures were performed in the SPSS© statistical package. Results: The number of remaining teeth was similar for LE and HE in the 35-year olds (25.8 versus 26.6), but in the older age groups LE had significantly a larger number of missing teeth. The LE groups (except in 65-year olds) exhibited significantly more PAL loss. LE had significantly fewer healthy gingival units in all but the 75-year age group. In all age groups, LE had fewer intact tooth surfaces and a significantly poorer occlusal function. The frequency of tooth cleaning measures and dietary habits did not differ between LE and HE. Conclusion: Educational level was shown to influence the oral conditions and should be considered in assessing risk, and in planning appropriate preventive measures. Zusammenfassung Ziel: Das Ziel der vorliegenden Studie war die Evaluation der Verbindung zwischen Bildungsniveau und Erkrankungen der Zähne, Behandlungsnotwendigkeit und oralen Hygienegewohnheiten. Material und Methoden: Randomisierte Gruppen von 35-, 50-, 65- und 75-Jährigen, die entsprechend ihres Bildungsniveau: niedriges Niveau (LE): Grundschule oder höheres Niveau (HE) klassifiziert wurden, wurden gebildet. Bei 1091 Personen wurden eine Anzahl von Charakteristika aufgezeichnet: (i) Anzahl der Zähne, (ii) parodontales Stützgewebeniveau (PAL), (iii) Karies, (iv) okklusale Funktion. Bildungsniveau, orale Hygiene und Eßgewohnheiten wurden selbst erfasst. Parameterfreie Variable wurden mit dem Chi-Quadrat test, dem Mann,Whitney U,Wilcoxon Rangsummentest und die parametergebundenen Variablen mit dem Student t -test (Signifikanz-Niveau 95 %) analysiert. Die Zwei-Wege ANOVA wurde auf dem DMF-s durchgeführt, um die Beziehung zwischen Alter und Bildungsniveau zu untersuchen. Alle statistischen Berechnungen wurden mit dem SPSS Statistik Programm vorgenommen. Ergebnisse: Die Anzahl der verbliebenen Zähne war zwischen LE und HE ähnlich bei den 35-Jährigen (25.8 vs. 26.6), aber in den älteren LE-Gruppen waren signifikant höhere Zahlen für fehlende Zähne. Die LE-Gruppen (ohne die 65-Jährigen) zeigten signifikant größeren PAL Verlust. LE hatten signifikant weniger gingivale Gesundheit bei den 75-Jährigen. In allen Altersgruppen hatten die LE weniger intakte Zahnoberflächen und signifikant geringere okklusale Funktion. Die Häufigkeit der Zahnreinigung und die Eßgewohnheiten unterschieden sich zwischen LE und HE nicht. Schlussfolgerung: Das Bildungsniveau hat einen Einfluss auf die oralen Bedingungen und sollte bei der Erfassung des Risikos und bei der Planung geeigneter Präventionsmaßnahmen beachtet werden. Résumé But: Le but de cette étude était d'évaluer l'association entre niveau d'éducation et maladie dentaire, besoins de traitement et habitudes d'hygiène orale. Matériel et méthodes: Des échantillons randomisés de sujets âgés de 35-, 50-, 65- et 75 ans, classés selon leur niveau d'éducation: [Bas (LE): école élémentaire, ou élevé (HE)] furent identifiés. Chez 1091 sujets, on a enregistré les caractéristiques suivantes: (i) nombre de dents, (ii) niveau d'attache parodontal (PAL), (iii) caries et (iv) fonction occlusale. Le niveau d'éducation, l'hygiène orale, et les habitudes alimentaires étaient rapportés par les patients eux-même. Les variables non paramétriques furent analysées par les tests chi carré, Mann,Whitney U,Wilcoxon rank sum, et les variables paramétriques par le test t de Student (niveau de signification 95%). 2-way ANOVA fut réalisé sur le DMFS pour rechercher l'interaction entre l'âge et le niveau d'éducation. Toutes les opérations statistiques furent menées par utilisation de SPSS©. Résultats: le nombre de dents restantesétait semblable pour LE et HE chez les sujets de 35 ans (25.8 vs. 26.6), mais dans les groupes plus âgés, LE présentait un nombre significativement plus important de dents absentes. Le groupe LE (sauf chez les patients de 65 ans) présentait plus de perte de PAL. LE présentait moins d'unités gingivales saines sauf dans le groupe de patients âgés de 75 ans. Dans tous les groupes d'âge, LE avait moins de surfaces dentaires intactes et une fonction occlusale significativement plus faible. La fréquence des mesures de nettoyage dentaire et les habitudes alimentaires n'étaient pas différentes entre les groupes LE et HE. Conclusion: Il est montré que le niveau d'éducation influence les conditions orales et cela doit être pris en considération lors de la mise en évidence du risque et dans la planification de mesures de prévention appropriées. [source] Using Insurance Claims and Demographic Data for Surveillance of Children's Oral HealthJOURNAL OF PUBLIC HEALTH DENTISTRY, Issue 1 2004Keith E. Heller DDS ABSTRACT Objectives: This paper examines the utility of using private insurance and Medicaid dental claims as well as demographic data for assessing the oral health of children aged 5,12 years in Genesee County, Michigan, communities. Methods: Dental insurance claims data from Delta Plan of Michigan and Michigan Medicaid, plus demographic data from the 1990 US Census (percent poverty) and from the 1995 National Center for Educational Statistics (percent free or reduced lunch eligibility), were compared to findings from two school-based oral health surveys. These surveys were the 1995 Genesee County Oral Health Survey and the 1998,2001 Mott Children's Health Center oral health screenings. Data were analyzed using zip codes, representing communities, as the comparison unit. Statistical comparisons using correlation coefficients were used to compare the findings from the six data sets. Results: Using the insurance claims and school-based data, some communities consistently demonstrated high levels of dental caries or treatment for the primary dentition. The demographic measures were significantly associated with many of the primary dentition survey measures. The demographic data were more useful in identifying communities with high levels of dental disease, particularly in the primary teeth, than the insurance claims data. Conclusions: When screening is not practical, readily available demographic data may provide valuable oral health surveillance information for identification of high-risk communities, but these data do not identify high-risk individuals. In these analyses, demographic data were more useful than dental insurance claims data for oral health surveillance purposes. [source] Dental health status of liver transplant candidatesLIVER TRANSPLANTATION, Issue 2 2007James Guggenheimer A prerequisite dental evaluation is usually recommended for potential organ transplant candidates. This is based on the premise that untreated dental disease may pose a risk for infection and sepsis, although there is no evidence that this has occurred in organ transplant candidates or recipients. The purpose of this study was to assess the prevalence of dental disease and oral health behaviors in a sample of liver transplant candidates (LTCs). Oral examinations were conducted on 300 LTCs for the presence of gingivitis, dental plaque, dental caries, periodontal disease, edentulism, and xerostomia. The prevalence of these conditions was compared with oral health data from national health surveys and examined for possible associations with most recent dental visit, smoking, and type of liver disease. Significant risk factors for plaque-related gingivitis included intervals of more than 1 yr since the last dental visit (P = 0.004), smoking (P = 0.03), and diuretic therapy (P = 0.005). Dental caries and periodontal disease were also significantly associated with intervals of more than 1 yr since the last dental visit (P = 0.004). LTCs with viral hepatitis or alcoholic cirrhosis had the highest smoking rate (78.8%). Higher rates of edentulism occurred among older LTCs who were less likely to have had a recent dental evaluation (mean 88 months). In conclusion, intervals of more than 1 yr since the last dental visit, smoking, and diuretic therapy appear to be the most significant determinants of dental disease and the need for a pretransplantation dental screening evaluation in LTCs. Edentulous patients should have periodic examinations for oral cancer. Liver Transpl 13:280,286, 2007. © 2007 AASLD. [source] Dentin matrix proteins and soluble factors: intrinsic regulatory signals for healing and resorption of dental and periodontal tissues?ORAL DISEASES, Issue 2 2004TA Silva Dentin contains numerous polypeptides and signaling molecules sequestered in a mineralized matrix. The exposure and release of these molecules occur as a consequence of injury to the pulp and periodontal ligament, which may result from luxation, orthodontic movement or infections of tooth and periodontal structures. When released at these sites, dentin constituents have the potential to act on different surrounding cells, including periodontal cells, osteoblasts, osteoclasts and inflammatory cells, and to affect the course of dental disease. Experimental studies have highlighted the interactions between dentin and cells from tooth and periodontal tissues and reveal dentin to be a cell adhesive, signaling and migratory stimulus for various mesenchymal and inflammatory cells. These results support the hypothesis that dentin molecules might function as regulatory signals for the healing and resorption of dental and periodontal tissues. Data from recent and classical investigations are summarized, many open questions are discussed, and current hypotheses concerning the mechanisms of tooth resorption and periodontal healing are outlined. Many questions regarding the importance of dentin as a source of multifunctional molecules remain unanswered and provide important directions for future studies. [source] Dental wear, wear rate, and dental disease in the African apesAMERICAN JOURNAL OF PRIMATOLOGY, Issue 6 2010Alison A. Elgart Abstract The African apes possess thinner enamel than do other hominoids, and a certain amount of dentin exposure may be advantageous in the processing of tough diets eaten by Gorilla. Dental wear (attrition plus abrasion) that erodes the enamel exposes the underlying dentin and creates additional cutting edges at the dentin-enamel junction. Hypothetically, efficiency of food processing increases with junction formation until an optimal amount is reached, but excessive wear hinders efficient food processing and may lead to sickness, reduced fecundity, and death. Occlusal surfaces of molars and incisors in three populations each of Gorilla and Pan were videotaped and digitized. The quantity of incisal and molar occlusal dental wear and the lengths of dentin,enamel junctions were measured in 220 adult and 31 juvenile gorilla and chimpanzee skulls. Rates of dental wear were calculated in juveniles by scoring the degree of wear between adjacent molars M1 and M2. Differences were compared by principal (major) axis analysis. ANOVAs compared means of wear amounts. Pearson correlation coefficients were calculated to compare the relationship between molar wear and incidence of dental disease. Results indicate that quantities of wear are significantly greater in permanent incisors and molars and juvenile molars of gorillas compared to chimpanzees. The lengths of dentin,enamel junctions were predominantly suboptimal. Western lowland gorillas have the highest quantities of wear and the most molars with suboptimal wear. The highest rates of wear are seen in Pan paniscus and Pan t. troglodytes, and the lowest rates are found in P.t. schweinfurthii and G. g. graueri. Among gorillas, G. b. beringei have the highest rates but low amounts of wear. Coefficients between wear and dental disease were low, but significant when all teeth were combined. Gorilla teeth are durable, and wear does not lead to mechanical senescence in this sample. Am. J. Primatol. 72:481,491, 2010. © 2010 Wiley-Liss, Inc. [source] Pott's puffy tumour mimicking preseptal cellulitisCLINICAL AND EXPERIMENTAL OPTOMETRY, Issue 4 2008Kristen P Lamoreau MA OD Periorbital swelling can be secondary to local infections (for example, hordeolum) or reflective of an adjacent infection (for example, dental disease). Rarely, periorbital swelling can indicate underlying sinus disease; Pott's puffy tumour is a unique and serious form of this process. This paper presents an unusual way in which a smouldering sinusitis can erode through bone and result in orbital cellulitis or intracranial infection. [source] Fluoride rinsing and dental health inequalities in 11-year-old children: an evaluation of a supervised school-based fluoride rinsing programme in EdinburghCOMMUNITY DENTISTRY AND ORAL EPIDEMIOLOGY, Issue 1 2009Kate A. Levin Abstract,,, Objectives:, Previous studies have shown that fluoride mouthrinsing programmes are effective in reducing caries among children and adolescents. National surveys of child dental health in the UK confirm that there is variation in oral health. In particular, children of low socioeconomic status in Scotland have a disproportionately high share of dental disease. This study aimed to evaluate an existing school-based fluoride mouthrinsing programme on dental caries in populations stratified by socioeconomic status. Methods:, A random sample of 1333 children surveyed by the National Dental Inspection Programme with average age 11.4 years was included in the study. Caries prevalence data were collected for the 661 rinsers and 672 nonrinsers. Chi-squared tests and t -tests were carried out to test differences in proportion and in mean D3MFT, respectively. The data were modelled using multilevel logistic regression, adjusting for age, sex, deprivation and rinse status. Results:, There is a strong negative association between deprivation and prevalence of D3MFT = 0. There is no significant difference in prevalence of D3MFT between rinsers and nonrinsers, however, mean D3MFT is greater for nonrinsers within each deprivation category. After adjusting for age, sex and deprivation, the odds of a tooth being decayed missing or filled for a child who rinsed are 0.79 (0.64, 0.98) compared with those of a child who did not. Conclusions:, Fluoride rinsing can be effectively targeted at children from deprived areas through school-based initiatives. There are some difficulties in recruiting all children from the more deprived backgrounds, but overall reductions in D3MFT were observed. [source] Risk indicators of edentulism, partial tooth loss and prosthetic status among black and white middle-aged and older adultsCOMMUNITY DENTISTRY AND ORAL EPIDEMIOLOGY, Issue 5 2001Teresa A. Dolan Abstract ,Objectives: To describe the prevalence and risk indicators of edentulism; to describe the frequencies of wearing removable dentures; to describe the prevalence and risk indicators of fixed prosthetic restorations; to test the hypothesis that fixed prosthetic restorations are most likely to have been placed in persons at lower risk for dental and periodontal diseases, and to test the hypothesis that, with dental disease, dental behaviors, dental attitudes and ability to afford crowns taken into account, blacks are less likely than whites to have received crowns. Methods: The Florida Dental Care Study is a cohort study of subjects 45 years old or older. A telephone screening interview was done as a first stage to identify 5254 subjects who met eligibility requirements and who self-reported whether they were edentulous. In a second stage, a subsample of dentate subjects was contacted after they completed their telephone screening interview. Of these, 873 subjects completed a baseline in-person interview and dental examination. Results: A total of 19% of first-stage subjects were edentulous. In a single multiple logistic regression, having a poorer self-rated level of general health was significantly associated with edentulism, as were being poor, older and white. Among the second-stage participants (all of whom were dentate), several prosthetic patterns were observed. For example, a total of 64% of maxillary full denture wearers reported wearing their denture all the time. Participants had also received numerous fixed prosthodontic services. The proportion of subjects with at least one crown varied widely by subject characteristics. Conclusions: A substantial percentage of non-ideal frequencies of wearing removable prostheses was reported, as were prosthesis-related soreness and broken prostheses. Although we expected and observed an association between having a fixed prosthetic crown and periodontal status, dental fillings, dental attitudes and financial resources, a residual association with race suggests that blacks are much less likely to receive prosthetic crowns. The several possible reasons for this circumstance warrant further investigation. [source] Oro-facial injuries in Central American and Caribbean sports games: a 20-year experienceDENTAL TRAUMATOLOGY, Issue 3 2005Enrique Amy Abstract,,, Dental services in sports competitions in the Games sponsored by the International Olympic Committee are mandatory. In every Central American, Pan American and Olympic Summer Games, as well as Winter Games, the Organizing Committee has to take all the necessary measures to assure dental services to all competitors. In all Olympic villages, as part of the medical services, a dental clinic is set up to treat any dental emergency that may arise during the Games. Almost every participating country in the Games has its own medical team and some may include a dentist. The major responsibilities of the team dentist as a member of the national sports delegation include: (i) education of the sports delegation about different oral and dental diseases and the illustration of possible problems that athletes or other personnel may encounter during the Games, (ii) adequate training and management of orofacial trauma during the competition, (iii) knowledge about the rules and regulations of the specific sport that the dentist is working, (iv) understanding of the anti-doping control regulations and procedures, (v) necessary skills to fabricate a custom-made and properly fitted mouthguard to all participants in contact or collision sports of the delegation. This study illustrates the dental services and occurrence of orofacial injury at the Central American and Caribbean Sports Games of the Puerto Rican Delegation for the past 20 years. A total of 2107 participants made up the six different delegations at these Games. Of these 279 or 13.2% were seen for different dental conditions. The incidence of acute or emergency orofacial conditions was 18 cases or 6% of the total participants. The most frequent injury was lip contusion with four cases and the sport that experienced more injuries was basketball with three cases. [source] Health outcomes associated with methamphetamine use among young people: a systematic reviewADDICTION, Issue 6 2010Brandon D. L. Marshall ABSTRACT Objectives Methamphetamine (MA) use among young people is of significant social, economic and public health concern to affected communities and policy makers. While responses have focused upon various perceived severe harms of MA use, effective public health interventions require a strong scientific evidence base. Methods We conducted a systematic review to identify scientific studies investigating health outcomes associated with MA use among young people aged 10,24 years. The International Classification of Diseases (ICD-10) was used to categorize outcomes and determine the level of evidence for each series of harms. Results We identified 47 eligible studies for review. Consistent associations were observed between MA use and several mental health outcomes, including depression, suicidal ideation and psychosis. Suicide and overdose appear to be significant sources of morbidity and mortality among young MA users. Evidence for a strong association between MA use and increased risk of human immunodeficiency virus (HIV) and other sexually transmitted infections is equivocal. Finally, we identified only weak evidence of an association between MA use and dental diseases among young people. Conclusions Available evidence indicates a consistent relationship between MA use and mental health outcomes (e.g. depression, psychosis) and an increased risk of mortality due to suicide and overdose. We found insufficient evidence of an association between MA use and other previously cited harms, including infectious diseases and dental outcomes. As such, future research of higher methodological quality is required to further investigate possible associations. Current interventions should focus attention upon MA-related health outcomes for which sound scientific evidence is available. [source] The relation of tobacco smoking to tooth loss among young adultsEUROPEAN JOURNAL OF ORAL SCIENCES, Issue 2 2004Pekka Ylöstalo Earlier studies have associated smoking with a higher rate of dental caries, periodontal disease and tooth loss. The aim of this cross-sectional study was to determine whether smoking is associated with tooth loss among young adults. The data consist of the 1966 birth cohort of Northern Finland, which is an unselected general population birth cohort (n = 12 058). The data were collected using a postal questionnaire in 1997,98 (n = 8690). Prevalence odds ratios and confidence intervals were estimated by applying a logistic regression model. It was found that smoking was associated with tooth loss in an exposure-dependent manner. The odds for those who smoked 16 or more pack-years were 5.30 (CI = 2.35,11.2) after adjustment for socio-economic and behavioral factors. Differences in socio-economic or health behavior are not likely to explain the findings since an exposure-response pattern was seen even when data was stratified according to sex, education and health-oriented lifestyle. A possible explanation for this association is a combination of treatment decisions and dental diseases, which are most likely associated with smoking in an exposure-dependent manner. [source] Oral disease experience of older adults seeking oral health servicesGERODONTOLOGY, Issue 2 2010Kavita P. Ahluwalia doi:10.1111/j.1741-2358.2009.00311.x Oral disease experience of older adults seeking oral health services Objective:, The objective of this investigation was to describe the dental disease (dental caries and alveolar bone loss) experience in a sample of community-dwelling older adults who regularly utilize dental services in New York City. Background:, Public financing for dental care directed at older adults in the United States is minimal. Improved preventive methods, primarily the use of fluorides, have resulted in declines in tooth loss, and concomitant increase in risk for dental diseases among older adults. While the oral disease burden in institutionalized elderly and those unable to access services is well-documented, the dental care needs of older adults who access dental services are not well documented. Materials and Methods:, Radiographic and record review were used to determine prevalence of dental caries, alveolar bone loss, frequency of service utilization, and medical status in this cross-sectional investigation of a sample of older adults (N = 200) using dental services at Columbia University College of Dental Medicine. Results:, Only 9% of the sample was completely edentulous, the mean DMFT was 19.9 and mean alveolar bone loss was 3.6 mm. Missing and Decayed Teeth accounted for 57.8% and 6.5% of the total caries burden respectively. Missing Teeth and alveolar bone loss increased with increasing age, but there was no increase in Decayed Teeth. Conclusions:, While access to and utilization of dental services may result in improved tooth retention, older adults who use dental services continue to have dental care needs, especially periodontal care needs. [source] Initial biofilm formation of Streptococcus sobrinus on various orthodontics appliancesJOURNAL OF ORAL REHABILITATION, Issue 11 2004D. Steinberg summary, Biofilms accumulate on hard and soft surface in the oral cavity. Accumulation of biofilms on orthodontic appliance bear scientific and clinical interest. The objection of this study was to examine the formation of dental biofilm by Streptococcus sobrinus on different types of orthodontics appliances, using a model consisting of host and bacterial constituents. The adsorption pattern of saliva to the orthodontics appliances was determined by means of gel electrophoresis coupled with computerized densitometry techniques. The amount of salivary proteins adsorbed onto the surfaces was measured using the Bradford method. Sucrose-dependent bacterial adhesion to the saliva-coated orthodontics appliances was tested by radioactive-labelled S. sobrinus. Our results show different adsorption patterns of salivary proteins to the various orthodontic appliances as modules, brackets, springs and intra oral elastics. Modules and brackets demonstrated the most affinity to salivary proteins. A surface dependent adhesion profile was recorded, showing a high affinity of albumin and amylase to modules. Bacterial accumulation was the highest on modules compared with springs which demonstrated the least bacterial adhesion. Our study demonstrates the specificity of biofilm formation on the different orthodontic appliances. Formation of a variety of dental biofilms has a significant impact on the progression of dental diseases associated with orthodontic treatment. [source] Toothbrushing Competency Among High-risk Grade One Students: an Evaluation of Two Methods of Dental Health EducationJOURNAL OF PUBLIC HEALTH DENTISTRY, Issue 4 2001Robert J. Hawkins BSc Abstract Objective: To evaluate the effectiveness of two methods of dental health education (DHE) for improving toothbrushing competency among grade one students at high risk for dental diseases. Methods: Fifty elementary schools in the former city of North York, Ontario, Canada, were assigned to one of two groups. In one group, students received a classroom-based DHE lesson that was reinforced by two small group sessions (n=243). In the other group, students received only a single classroom-based DHE lesson (n=206). Trained examiners assessed 11 toothbrushing skills at pre- and postintervention. Results: At the preintervention test, few significant differences were found between the groups and many students did not display competency in fundamental oral health skills, such as placing a toothbrush at the gum line. Following DHE interventions, students in both groups demonstrated improvements in most skills. A significantly higher proportion of students who received both classroom and small group sessions displayed gains in competency in three skills, compared to students receiving only a classroom lesson. These skills were brushing anterior lingual surfaces, brushing posterior lingual surfaces, and brushing all areas in a routine fashion. Students receiving only a classroom session did not display greater improvements in any skill areas compared to "classroom plus small group" students. Some students in both groups still lacked fundamental skills at the end of the DHE program. Conclusions: While one must exercise caution in interpreting the results due to several methodologic limitations, findings suggest that for high-risk grade one students, a classroom-based lesson combined with small group sessions is a more effective method of improving toothbrushing skills compared to a single classroom-based lesson. [source] Xerostomia: an update for cliniciansAUSTRALIAN DENTAL JOURNAL, Issue 3 2010MS Hopcraft Abstract Saliva plays an important protective role in the oral environment, and reductions in saliva quantity are known to increase the risk of oral diseases. Importantly, xerostomia or the perception of a dry mouth is now being recognized as an important risk factor for dental diseases. Furthermore, the subjective sensation of a dry mouth is a debilitating condition in itself that impacts on the quality of life of sufferers. With approximately 1 in 5 people reporting some form of dry mouth, and an increasing prevalence in the elderly, it is important for clinicians to have a thorough understanding of this problem. The aim of this paper is to review some of the literature relating to xerostomia in order to provide an evidence based update for clinicians. [source] Caries experience in the primary dentition among French 6-year-olds between 1991 and 2000COMMUNITY DENTISTRY AND ORAL EPIDEMIOLOGY, Issue 5 2005Colette Adam Abstract , Background:, There are few national caries preventive policies for children in France. Various surveys suggest that in the late 1980s, oral health of the 6-year olds in France was poorer than in those of other European countries. In Val de Marne (a Department just east of Paris) a public dental service was established in 1991. A programme to inform preschool staff about dental diseases was commenced and volunteers brought oral health information to parents and health professionals. Periodical monitoring of primary tooth caries of 6-year olds was planned. Aim:, The aim of the study was to evaluate changes in primary tooth caries in 6-year olds over the 10 years of the programme. Methods:, Participating 6-year olds, randomly selected, were examined in schools by dentists. Clinical data were collected (WHO criteria). Sociodemographic data were collected through questionnaire. Statistical analysis involved comparison of mean values, variance analysis and chi-square test for categorical variables. Results:, The proportions of children with caries experience were, 38.9%, 30.6% and 22.2% in 1991, 1995 and 2000 respectively (P < 0.01). The dft index decreased from 1.74 to 1.39 and 1.05 respectively. About 75% of children with dental caries remained untreated. Children of non-European native parents or belonging to low socioeconomic families remained those most affected by dental caries in 2000. Conclusion:, Dental caries in 6-year olds improved between 1991 and 2000 in Val de Marne but caries remained a socially inequitable disease. Most children did not have access to dental care. The situation requires changes to the dental care provision system. [source] | |||||||||||||||||||||||||||||||
