Rural and Urban Disparities in Caries Prevalence in Children with Unmet Dental Needs: The New England Children's Amalgam Trial

JOURNAL OF PUBLIC HEALTH DENTISTRY, Issue 1 2008
Nancy Nairi Maserejian ScD
Abstract Objectives: To compare the prevalence of caries between rural and urban children with unmet dental health needs who participated in the New England Children's Amalgam Trial. Methods: Baseline tooth and surface caries were clinically assessed in children from rural Maine (n = 243) and urban Boston (n = 291), who were aged 6 to 10 years, with two or more posterior carious teeth and no previous amalgam restorations. Statistical analyses used negative binomial models for primary dentition caries and zero-inflated models for permanent dentition caries. Results: Urban children had a higher mean number of carious primary surfaces (8.5 versus 7.4) and teeth (4.5 versus 3.9) than rural children. The difference remained statistically significant after adjusting for sociodemographic factors and toothbrushing frequency. In permanent dentition, urban children were approximately three times as likely to have any carious surfaces or teeth. However, rural/urban dwelling was not statistically significant in the linear analysis of caries prevalence among children with any permanent dentition caries. Covariates that were statistically significant in all models were age and number of teeth. Toothbrushing frequency was also important for permanent teeth. Conclusions: Within this population of New England children with unmet oral health needs, significant differences were apparent between rural and urban children in the extent of untreated dental decay. Results indicate that families who agree to participate in programs offering reduced cost or free dental care may present with varying amounts of dental need based on geographic location. [source]

Prevalence of salivary Streptococcus mutans in mothers and in their preschool children

INTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 1 2002
I. Thorild
Summary. Objectives. To establish the prevalence and possible relationship of oral Streptococcusmutans colonization in mother,child pairs. Design and setting. An analytical cross-sectional study was carried out at a well-baby evaluation clinic held at the Public Dental Clinic, Varberg, Sweden. Sample and methods. Two hundred preschool children, 100 of which were 18 months old and the remaining 100 were 3 years old, and their mothers attended the clinic. All mothers were interviewed and their children's medical history, oral hygiene routines and dietary habits established. All children were clinically examined. The presence and level of S. mutans was estimated in the mother,child pairs with the aid of the Strip mutans chair-side test. Results. Nearly 50% of mothers exhibited high levels of salivary S. mutans, prevalence among the 18-month- and 3-year-olds was 30% and 42%, respectively. A statistically significant (P < 0·01) mother,child relationship was found; a greater presence in mothers led to a higher number of children found harbouring the bacteria. Logistic regression analysis found that high maternal S. mutans levels (P < 0·001), daily sweet intake (P < 0·01) and sugary drinks in feeding bottles (P < 0·05) were significant factors for S. mutans colonization in children. Absence of daily toothbrushing and use of feeding bottles at night failed to fit into the model. Caries prevalence (initial and manifest decayed surfaces) was significantly related to S. mutans colonization (P < 0·01). Conclusion. The results support the concept of vertical transmission (mother,child), emphasizing the importance of the dietary component, and justifying a primary preventive approach with targeted action directed at mothers with high levels of S. mutans colonization.

Caries prevalence in Belgian children: a review

INTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 3 2001
J. Vanobbergen
A review of epidemiological surveys on dental caries prevalence, published between 1980 and 1999 in Belgian children, was compiled through a literature search. The number of studies performed in Belgium to date is limited. Methodological differences and confounding factors, especially socio-demographic influences, limit national comparisons of caries prevalence data. Although exact comparisons are difficult, data suggests a decline in caries prevalence in 5, 7 and 12 year-old Belgian schoolchildren in the last 20 years. In the primary dentition dmft values have decreased from 2·66 (1981) to 1·38 (1994) in 5-year-olds and from 4·1 (1983) to 2·24 (1996) in 7-year-olds. In 12-year-olds DMFT values in the permanent dentition have decreased from 3·9 (1983) to 1·93 (1994). WHO goals for the year 2000 appear to have been already reached in Flanders, with a recent estimate of 1·93 for DMFT in 12-year-olds and 56% of children being recorded as caries free at the age of 5. Continuing efforts are needed to screen the oral health of different age groups but standardised criteria and sampling procedures should be used if benefits are to be gained from national and international comparison. Data has often been limited to small selected areas and information representing the entire community of Flanders or Wallonia would be of particular value. [source]

Abstract Objectives: To determine the experience, prevalence, and severity of dental caries in adolescents naturally exposed to various fluoride concentrations. Methods: A cross-sectional census was conducted on 1,538 adolescents aged 12 and 15 years living at high altitude above sea level (>2,000 m or >6,560 ft) in above-optimal fluoridated communities (levels ranging from 1.38 to 3.07 ppm) of Hidalgo, Mexico. Sociodemographic and socioeconomic data were collected using questionnaires. Two previously trained and standardized examiners performed the dental exams. Results: Caries prevalence was 48.6 percent and mean of decay, missing, and filling teeth (DMFT) for the whole population was 1.15 ± 1.17. In terms of severity, 9.6 percent of the adolescents had DMFT , 4, and 1.7 percent had ,7. The significant caries index (SiC) was 2.41 in the group of 12-year-olds, and 3.46 in the 15-year-olds. Higher experience and prevalence were observed in girls, in children with dental visit in the past year, those in the wealthiest socioeconomic status (SES) (quartiles 2, 3, and 4), those whose locale of residence is in San Marcos and Tula Centro, and in fluorosis-free children and those with moderate/severe fluorosis. In an analysis of caries severity (DMFT , 4), both adolescents with very mild/mild and moderate/severe dental fluorosis have higher caries severity. Conclusions: The results indicated that caries experience, prevalence, and severity as well as SiC index among 12- and 15-year-old adolescents were relatively low. Sociodemographic and socioeconomic variables commonly associated with dental caries were also observed in Mexican adolescents. Unlike other studies, we found that caries increased with higher SES. Fluoride exposure (measured through fluorosis presence) does not appear to be reducing the caries prevalence (DMFT > 0) or caries severity (DMFT , 4) in these high-altitude communities. [source]

Dental Caries Experience and Factors among Preschoolers in Southeastern Mexico: A Brief Communication

JOURNAL OF PUBLIC HEALTH DENTISTRY, Issue 2 2006
América Segovia-Villanueva MSc
Abstract Objective: To examine the Association between dental caries prevalence and selected variables in preschool children. Methods: A cross-sectional study was carried out with 1,303 preschoolers (ages 3,6 years old), and the mothers completed questionnaires. The children were examined by one of three standardized dental examiners. Logistic regression was performed to identify Associations between dental caries and other factors. Results: Mean dmft was 1.54+2.47, with 44.1% of children having dmft>O. Caries prevalence was Associated with older children (OR=1.39); medium (OR=1.66) and low (OR=2.41) socioeconomic levels; mediocre (OR=l.71) and inadequate (OR=2.25) hygiene; negative attitude toward oral health (OR=1.51); and the presence of enamel defects (OR= 1.74). Conclusion: Both overall caries prevalence and dmft index were relatively low. The results of this study substantiate previous reports in the international literature for clinical, behavior, socio-demographic, and socio-economic variables that contribute to dental caries in Mexican children.

Agustsdottir H, Gudmundsdottir H, Eggertsson H, Jonsson SH, Gudlaugsson JO, Saemundsson SR, Eliasson ST, Arnadottir IB, Holbrook WP. Caries prevalence of permanent teeth: a national survey of children in Iceland using ICDAS. Community Dent Oral Epidemiol 2010; 38: 299,309. © John Wiley & Sons A/S Abstract,,, Objectives:, The Icelandic Oral Health Survey aimed to obtain new national data on the oral health of Icelandic children and teenagers. Methods:, A representative stratified random cluster sample of 2251 Icelandic children in first, seventh and 10th grade, aged approximately 6-, 12- and 15-years old was examined for caries prevalence using the ICDAS criteria. Bite-wing digital radiographs were obtained for the children in 7th and 10th grade. Results:, D3MFT scores by visual examination of 6-, 12- and 15-year olds were 0.12, 1.43 and 2.78 respectively but when including radiographs, the D3MFT rose to 2.11 at 12 years and 4.25 at 15 years. The Significant Caries Index, SiC, by visual examination for 12 and 15 y was 3.7 and 6.7 respectively but was 4.7 for 12 y and 8.9 for 15 y with radiographs. In all age groups and at most disease levels, caries was active in the majority of the lesions (58,100%). The percentage of children with no visually detectable caries at D3/D1 level was 93%/74% for 6 years, 48%/22% for 12 years and 35%/16% for 15 years. When radiographs were included the percentage reduced to 34%/15% for 12 years and 20%/6% for 15 years. Approximately 80% of 12- and 15-year-olds had at least one of their first molars sealed, with the mean number of sealed first molars being 2.2 among 12 y and 2.0 among 15 y. Conclusions:, Caries levels were higher than expected in this national survey and further away from the goals of the National Health Plan for 2010 than anticipated. Caries distribution was skewed with more than half of the children having low caries scores but a wide distribution of caries experience was seen among the remaining population. [source]

Caries and dental fluorosis in a western Saharan population of refugee children

EUROPEAN JOURNAL OF ORAL SCIENCES, Issue 6 2008
José Manuel Almerich-Silla
The aim of this study was to investigate the relationship between dental fluorosis and dental caries among western Saharan refugee children. The western Saharan child population is characterized by adverse living conditions, an unbalanced diet, poor oral hygiene habits, and a concentration of fluoride in the drinking water of around 2 p.p.m. (2 mg l,1). A sample consisting of 360 children, 6,7 yr of age, and 212 children, 11,13 yr of age, was obtained from four refugee camps (Smara, Awsard, El-Aaiun, and 27-February) situated in the vicinity of Tindouf (southern Algeria). The children were examined using the World Health Organization criteria for caries diagnosis and Dean's index for fluorosis. The decayed, missing or filled teeth (DMFT) score was 0.48 in the 6,7-yr-old children and 1.69 in the 11,13-yr-old children, with a caries prevalence (DMFT > 0 or decayed and filled primary teeth (dft) > 0) of 47.2% and 63.2%, respectively. Among the 6,7 yr-old children examined, 36.9% were free of fluorosis, 15.6% presented moderate fluorosis, and 7.8% presented severe fluorosis. Among 11,13 yr-old children, only 4.2% were free of fluorosis, 30.2% exhibited moderate fluorosis, and 27.4% presented severe fluorosis. The mean DMFT, decayed permanent teeth (DT), and caries prevalence (DMFT > 0 and DMFT or dft > 0) scores were significantly higher among the children affected by severe fluorosis, suggesting that severe fluorosis might increase the susceptibility to dental caries.

Impact of treatment provision on the epidemiological recording of root caries

EUROPEAN JOURNAL OF ORAL SCIENCES, Issue 1 2000
A. W. G. Walls
The estimation of root caries prevalence and the identification of risk factors for decay depend upon the successful identification of carious lesions in epidemiological studies. Root surface restorations can either be placed to manage decay or cervical wear/sensitivity. The handling of data for restorations during epidemiological surveys is critical to the accurate assessment of caries prevalence. The objective of this study was to determine the relative frequency of dentists' placing root surface restorations according to their reason for placement. Data for 696 restorations were recorded from 35 dentists. Forty-five % of restorations were placed because of decay compared with 55% for cervical wear/sensitivity. There were no significant differences in proportion of placement of restoration with age of the patient or between regular and irregular attenders of different ages. Using these data a correction factor was developed for inclusion in the Root Caries Index (RCI) to make allowance for the proportion of restorations placed because of wear/sensitivity. When this correction factor was introduced into an existing data-set for root caries, the RCI was reduced for all groups. This reduction was greatest in regular attenders. When these data were analysed without making allowance for treatment effects, there was a significant difference in RCI between regular and irregular attenders. When the correction factor was applied to these data, this difference was eliminated. [source]

Oral health status and treatment needs among school children in Sana'a City, Yemen. Abstract:, Data on the oral health status and treatment needs among Yemeni children are lacking. Objectives:, To assess caries prevalence, treatment needs and gingival health status among school children in Sana'a City and to examine how these are affected by age, gender and khat chewing. Methods:, 1489 children (6- to 14-year old) were randomly selected from 27 schools representing all nine districts of Sana'a City. Dental caries and treatment needs were evaluated using standard WHO oral survey methods. The plaque index (PI), calculus index (CI) and the gingival index (GI), recorded at the six Ramfjord's teeth, were used to assess gingival health status. Results:, 4.1% of the study subjects were caries-free. Prevalence of these was significantly higher among the males. Overall, mean dmfs, dmft, DMFS and DMFT scores were 8.45, 4.16, 3.59 and 2.25 respectively. The decayed component accounted for >85% of the scores. The highest dmfs/dmft means were found among the 6,8 years age group, while the highest DMFS/DMFT means were scored by the 12,14 years age group. The need for restorative treatment and extractions was high; the former was significantly higher among the females. All subjects had gingivitis; the mean PI, CI and GI were 1.25, 0.3 and 1.36 respectively. Khat chewing did not affect caries experience; however, it was significantly associated with higher PI, CI and GI scores. Conclusions:, The prevalence of caries, gingivitis and treatment needs among children in Sana'a city is high. More surveys in other Yemeni cities to generate comprehensive data are required.

Tooth wear in two ancient populations of the Khazar Kaganat region in the Ukraine

INTERNATIONAL JOURNAL OF OSTEOARCHAEOLOGY, Issue 1 2007
W. H. Arnold
Abstract Tooth wear is a common phenomenon in archaeological material. It has been related to the abrasiveness of diet and to the tribological attrition of teeth of individuals. Numerous investigations have been carried out in north and middle American samples as well as African anthropological material. Not much is known about tooth wear in European cultures. Eleven skulls from Chervona Gusarovka, and 14 skulls from the Upper Saltov sites of the Khazar Kaganat region (8th,10th centuries AD) in eastern Ukraine, with different diets were examined. A total of 208 teeth were studied for tooth wear, caries prevalence and periodontal status. Abrasion grades were determined according to a standardised classification and statistically evaluated. Periodontal status was measured using the distance between the enamel-cementum junction and alveolar crest and the gingival attachment level respectively. Tooth wear was significantly different (P,<,0.01) between the two populations. A low caries prevalence of 4.2% in the Chervona Gusarovka population and 1.7% in the Upper Saltov population was found. Significantly more alveolar crest bone resorption on the lingual side was found in the premolars and anterior teeth of the Chervona Gusarovka population. No significant differences were found regarding gingival attachment levels and gingival recession. It is concluded that the content and mode of food preparation influenced tooth wear, as reflected by the prevalence of dental caries and periodontal diseases in these ancient populations.

Behaviour guidance in dental treatment of patients with autism spectrum disorder

INTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 6 2009
CHEEN Y. LOO
Background., Autism spectrum disorder (ASD) is a neurodevelopmental disorder categorized into autism, pervasive developmental disorder , not otherwise specified (PDD-NOS) and Asperger syndrome. Aims., To identify factors associated with the behaviour of patients with ASD in a dental setting, use of general anaesthesia (GA), and protective stabilization. Design., The dental charts of 395 patients with ASD patients and 386 unaffected patients were reviewed. The following data were analysed: ASD diagnosis, age, gender, residence, seizure disorder, additional diagnosis (mental retardation, cerebral palsy, self-injurious behaviour or pica), medications, caries prevalence and severity, dental treatment history, behaviour, and behaviour guidance technique(s) used. Results., Within both groups, younger patients were more uncooperative. ASD patients with autism were more uncooperative than patients with PDD-NOS; patients with an additional diagnosis were also more uncooperative. ASD patients with higher caries severity, who were uncooperative or female, were more likely to require GA. Use of protective stabilization was associated with lower caries severity, presence of seizure disorder, uncooperative behaviour, male gender, or residency in a group home/institution. Conclusions., Autism spectrum disorder patients with autism, younger age and an additional diagnosis were more uncooperative. Factors associated with the use of GA and protective stabilization in patients with ASD were also identified. [source]

INTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 4 2008
MALIN STENSSON
Objective., The aim of this study was to investigate oral health and its determinants in 3-year-old and 6-year-old children with asthma. Methods and subjects., Caries and gingivitis were examined in 127 asthmatic (all children with asthma in a selected area and born during a specific time period) and 117 matched, healthy control children. The parents were interviewed regarding various oral-health-related factors. Results., The mean dfs (± standard deviation) in the 3-year-old with asthma was 1.4 ± 3.2 compared with 0.5 ± 1.2 in the controls (P < 0.05). The corresponding figures for the 6-year-old were 2.5 ± 3.9 and 1.8 ± 2.8. The 3-year-old asthmatic children had more gingival bleeding than the healthy controls (P < 0.05). There were no significant differences in gingivitis in the 6-year-old children. Asthmatic children reported higher consumption of sugar-containing drinks and were more frequently mouthbreathers than healthy children (P < 0.05). In 3-year-old children with asthma and immigrant background, the mean dfs was higher compared with immigrant children in the control group (P < 0.01). Conclusion., The results indicate that preschool children with asthma have higher caries prevalence than healthy children. The factors discriminating for caries in asthmatic children are higher intake of sugary drinks, mouth breathing, and immigrant background. [source]

Outcome of an oral health outreach programme for preschool children in a low socioeconomic multicultural area

INTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 2 2008
INGER WENNHALL
Background., Despite a significant reduction in the prevalence of dental caries, childhood tooth decay is still a public health problem in both developed and developing countries. Objective., The aim of this study was to evaluate the caries preventive effect of an oral health programme for preschool children living in a low socioeconomic multicultural area in the city of Malmö, Sweden. Methods., Eight hundred and four 2-year-old children were enrolled and recalled every third month between ages 2 and 3 and semi-annually between ages 3 and 5 years. From an outreach facility, parents were instructed on oral health with a focus on toothbrushing and diet, and provided fluoride tablets free of charge. Participants completed a clinical examination and a structured interview at age of 5 years, at which point 651 children (81%) remained in the programme. The results of the intervention group were compared with a non-intervention reference group consisting of 201 5-year-old children from the same district. Results., In the intervention group, 96% attended four or more of their scheduled appointments, and mean caries prevalence was significantly lower than in the reference group (5.4 deft vs. 6.9 deft; P < 0.001). The prevented defs fraction was 27%. Parents' daily assistance with toothbrushing and administering fluoride tablets was significantly better in the intervention group than in the reference group (P < 0.05). Conclusion., This study demonstrated that the early start of oral health programme had a significant beneficial effect on caries prevalence after 3 years. [source]

Dental caries and associated factors in 12-year-old schoolchildren in Thiruvananthapuram, Kerala, India

INTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 6 2005
J. DAVID
Summary Objectives. The aims of the present study were to describe the dental health status of 12-year-old schoolchildren in Thiruvananthapuram, Kerala, India, and to identify sociodemographic factors, oral health behaviours, attitudes and knowledge related to dental caries experience. Methods. The study took the form of a cross-sectional survey of 838 children in upper primary schools. A two-stage cluster sampling technique was used. Dental caries was measured using World Health Organization criteria. Sociodemographic factors, oral health behaviours, attitudes and knowledge were assessed by a self-administered questionnaire. Results. The prevalence of dental caries in the permanent dentition was 27%. The mean number of decayed, missing and filled teeth was 0·5 (SD = 0·9). The decayed component (D) constituted 91% of the total number of decayed, missing and filled teeth (DMFT). Multiple logistic regression analysis showed that children had a higher risk of having dental caries if they lived in urban area [OR = 1·5, 95% confidence interval (CI) = 1·1,2·1], had visited a dentist (OR = 1·6, 95% CI = 1·2,2·2), did not use a toothbrush (OR = 1·9, 95% CI = 1·2,2·9), consumed sweets (OR = 1·4, 95% CI = 1·0,1·9) or performed poorly in school (OR = 1·7, 95% CI = 1·0,2·3). Conclusions. The prevalence of caries in this sample of 12-year-old schoolchildren was low compared to that in other developing countries. The present study indicated that urban living conditions were associated with more dental caries. Since urbanization is rapid in India, oral health promotion at the present time would be valuable to prevent increased caries prevalence. [source]

Oral health status in relation to ethnicity of children in the Municipality of Copenhagen, Denmark

INTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 3 2003
A. Sundby
Summary. Approximately 25% of children under the age of 18 in the Municipality of Copenhagen have a non-Danish ethnic background, and it is suspected that there may be major inequalities in oral health as a result. Objectives. The objectives of this study were to describe the occurrence of dental caries in different ethnic minorities, and to analyse whether the dental caries experience of the children may be affected by cultural and behavioural differences. Materials and methods. The study was conducted in Copenhagen as a cross-sectional investigation of 794 children, aged 3 and 5 years old (preschool), 7 years old (Grade 1) and 15 years old (Grade 9). Children of Danish, Turkish, Pakistani, Albanian, Somali and Arabian backgrounds were selected by convenience sampling. Epidemiological data were retrieved from the Danish Recording System for the Public Dental Health Services (SCOR) and sociological data were collected by postal questionnaires. Results. Marked differences in dental caries prevalence were observed when different ethnic minorities were compared to Danish children. These were most prominent for the primary dentition. At age 7, 53% of the Danish and 84% of the Albanian children were affected by dental caries, the mean caries experience was 3·5 dmfs (decayed, missed and filled surfaces) and 13·8 dmfs, respectively. Caries in incisors and/or smooth surfaces was observed in 10% of the Danish children and 48% of the Albanian children. There were cultural differences in dental attendance and self-care practices of children and parents. These socio-behavioural factors may help to explain the differences in dental caries prevalence and severity. Conclusions. Development of appropriate oral health promotion strategies is urgently needed to improve oral health behaviour and attitudes of parents and children of ethnic minorities. Preventive programs should be organized at local community level in close collaboration with key persons of ethnic minority societies. [source]

The use of restraint in the treatment of paediatric dental patients: old and new insights

INTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 6 2002
B. Peretz
Summary. Objective. This article reviews aspects of the restraint strategies in paediatric dentistry that have been reviewed in recent years and point out those strategies that remain controversial as well as questionable. Methods. Studies that evaluated demographic and cultural factors that influence dentists' use of restraint, discussion of the rationale behind the use of restraint, the role of parents, informed consent, use of restraints at the undergraduate and at the postgraduate level, and some ethical questions were selected. Conclusions. Practice location, caries prevalence, and the educational backgrounds of the dentist played a role in the selection of behavioural strategies. Use of these techniques varied depending on the age of the dentist and the dental school from which the dentist had graduated. Parents are one leg of the child/dentist/parent triangle and therefore have a role to play in the determination of treatment strategies. Dentists must select techniques that help to instil a positive dental attitude in the child by performing treatment effectively and efficiently. Dentists must inform parents of all aspects of the applied strategy and must have their approval. [source]

Caries prevalence in Belgian children: a review

Factors Associated with Dental Caries Experience in 1-Year-Old Children

JOURNAL OF PUBLIC HEALTH DENTISTRY, Issue 2 2008
John J. Warren DDS
Abstract Objectives: Dental caries in early childhood is an important public health problem. Previous studies have examined risk factors, but they have focused on children during the later stages of the disease process. The purpose of this study was to assess the factors associated with caries in children aged 6 to 24 months as part of a cross-sectional analysis. Methods: Two hundred twelve mothers with children 6 to 24 months of age were recruited from Special Supplemental Nutrition Program for Women, Infants, and Children clinic sites in southeastern Iowa for participation in a longitudinal study of dental caries. Baseline assessments included detailed questions regarding the children's beverage consumption, oral hygiene, and family socioeconomic status. Dental caries examinations using the d1d2-3f criteria and semiquantitative assessments of salivary mutans streptococci (MS) levels of mother and child were also conducted. Counts of the number of teeth with visible plaque were recorded for maxillary and mandibular molars and incisors. Results: Of the 212 child/mother pairs, 187 children had teeth. Among these children, the mean age was 14 months, and 23 of the children exhibited either d1, d2-3, or filled lesions. Presence of caries was significantly associated with older age, presence of MS in children, family income <$25,000 per year, and proportion of teeth with visible plaque. Conclusions: Results suggest that not only microbial measures, including MS and plaque levels, are closely associated with caries in very young children, but that other age-related factors may also be associated with caries. Continued study is necessary to more fully assess the risk factors for caries prevalence and incidence in preschool children. [source]

Rural and Urban Disparities in Caries Prevalence in Children with Unmet Dental Needs: The New England Children's Amalgam Trial

Prevalence and Severity of Dental Caries in Adolescents Aged 12 and 15 Living in Communities with Various Fluoride Concentrations

Oral Health Status of San Francisco Public School Kindergarteners 2000,2005

JOURNAL OF PUBLIC HEALTH DENTISTRY, Issue 4 2006
Lisa H. Chung DDS
Abstract Objectives:To determine the prevalence of dental caries and oral health disparities in San Francisco kindergarten public school children from 2000,2005. Methods:The San Francisco Department of Public Health in partnership with the San Francisco Dental Society and assistance from the National Dental Association, has been conducting annual dental screenings of kindergarten children enrolled in the San Francisco Unified School District since 2000. Outcomes assessed from this series of cross-sectional screenings included prevalence of caries experience, untreated caries, treatment needs, and caries severity by child's sex, race/ethnicity, residential zip code, and a proxy for socioeconomic status. Results:Of 76 eligible schools, 62,72 participated, and 86,92% of enrolled children (n=3,354-3,527) were screened yearly. Although there was a small, significant decrease over the time period, in 2005, 50.1% of children had caries experience; 28.8% had untreated caries and 7.6% had urgent treatment needs. Each year caries prevalence was greatest for Asian children, those attending schools with > 50% children eligible for the free or reduced-price meal program, and children living in zip codes in and around Chinatown and San Francisco's southern border. Conclusions:Despite signs of improvement, caries remains a public health problem especially in Asian and Hispanic children, and children living in certain sections of San Francisco. [source]

Specific Caries Index: A New System for Describing Untreated Dental Caries Experience in Developing Countries

JOURNAL OF PUBLIC HEALTH DENTISTRY, Issue 4 2006
Shashidhar Acharya MDS
Abstract Objectives:To develop a reproducible surface-specific caries index that provided qualitative and quantitative information about untreated dental caries, that could be used in conjunction with the DMFS index and would provide information on not only the caries prevalence but also the location and type of caries lesion in an individual based on clinical examination. Methods:Untreated carious lesions were divided into six types based on the location of the lesions.339 rural school children in the age group of 12,15 years were examined for dental caries using both the DMFS index and the Specific Caries Index. Results:Type 1 and 2 were found to be the most common type of caries lesions. The reproducibility of the Specific Caries Index was also found to be good. Conclusions:Encouraging indications about the validity and reproducibility of this new caries index was found, suggesting the need for further studies to test its applicability in larger and different populations.

Dental Caries Experience and Factors among Preschoolers in Southeastern Mexico: A Brief Communication

Fluoridation and Social Equity

JOURNAL OF PUBLIC HEALTH DENTISTRY, Issue 4 2002
Brian A. Burt BDS
Abstract The overall reduction in caries prevalence and severity in the United States over recent decades is largely due to widespread exposure to fluoride, most notably from the fluoridation of drinking waters. Despite this overall reduction, however, caries distribution today remains skewed, with the poor and deprived carrying a disproportionate share of the disease burden. Dental caries, like many other diseases, is directly related to low socioeconomic status (SES). In some communities, however, caries experience has now diminished to the point where the need for continuing water fluoridation is being questioned. This paper argues that water fluoridation is still needed because it is the most effective and practical method of reducing the SES-based disparities in the burden of dental caries. There is no practical alternative to water fluoridation for reducing these disparities in the United States. For example, a school dental service, like those in many other high-income countries, would require the allocation of substantial public resources, and as such is not likely to occur soon. But studies in the United States, Britain, Australia, and New Zealand have demonstrated that fluoridation not only reduces the overall prevalence and severity of caries, but also reduces the disparities between SES groups. Water fluoridation has been named as one of the 10 major public health achievements of the 20th century by the Centers for Disease Control and Prevention, and promoting it is a Healthy People objective for the year 2010. Within the social context of the United States, water fluoridation is probably the most significant step we can take toward reducing the disparities in dental caries. It therefore should remain as a public health priority. [source]

Discriminant validity of the International Caries Detection and Assessment System (ICDAS) and comparability with World Health Organization criteria in a cross-sectional study. Community Dent Oral Epidemiol 2010; 38: 398,407. © 2010 John Wiley & Sons A/S Abstract,,, Objectives:, The aim of this cross-sectional study in preschool children was to assess the ability of International Caries Detection and Assessment System (ICDAS) in discriminating socioeconomic factors associated with the presence of caries lesions at both noncavitated and cavitated thresholds and to compare with the standard World Health Organization (WHO) criteria. Methods:, The study was carried out in Amparo, Brazil, during the National Day of Children's Vaccination including 252 children aged 36,59 months. The same child was independently examined by two calibrated examiners, one using the ICDAS and the other using WHO criteria. Socioeconomic information was also recorded. Associations between socioeconomic factors and presence of caries assessed as binary (caries prevalence) and count outcome (actual dmfs values) obtained by WHO criteria and by ICDAS at noncavitated and cavitated thresholds were evaluated by Poisson regression analysis with robust variance. Results:, Some covariates were significantly associated with the presence of caries evaluated by the WHO criteria and by ICDAS (using score 3 as cut-off point). When noncavitated scores of ICDAS were used to calculate the presence of caries, the discriminant power decreased. When dmfs values were used as outcome, no differences in the associations were observed between two systems or using noncavitated caries lesions. Conclusion:, Cavitated scores of ICDAS present similar discriminant validity compared with WHO criteria when presence of caries is used as outcome; however, when actual dmfs values are used, no differences are observed in using noncavitated or cavitated caries lesions.

Abstract , Objectives:, To determine the pattern of caries experience across teeth and surfaces in an adult population depending on age and exposure to water fluoridation. Methods:, Between November 2002 and March 2003 a total of 973 subjects aged 17,51 years had a clinical examination using visual and tactile criteria. Subsequent to this examination, bitewing radiographs were taken and viewed separately. Approximal and occlusal surfaces of molars and premolars were examined on the radiographs. Results:, Caries experience was relatively low, with mean DMFS scores of 3.21, 5.12, 9.61, 13.04 and 24.35 for subjects aged 17,20, 21,25, 26,30, 31,35 and 36,51 years respectively. The first molar teeth had the greatest caries experience, and occlusal surfaces had more caries experience than approximal surfaces. Subjects with a lifetime exposure to fluoridated drinking water had significantly lower caries experience than those who had no exposure to fluoridated drinking water. Conclusion:, This study showed that caries prevalence, although relatively low in the study population, was found predominantly in occlusal surfaces, with an increasing prevalence in approximal surfaces of posterior teeth in older subjects. Subjects with a lifetime exposure to fluoridated drinking water had a lower level of caries experience than those with no exposure to fluoridated drinking water, and this was more noticeable in approximal surfaces than occlusal surfaces.
