Lost Teeth (lost + tooth)
Selected AbstractsSingle-tooth implant treatment in the anterior region of the maxilla for treatment of tooth loss after trauma: a retrospective clinical and interview studyDENTAL TRAUMATOLOGY, Issue 3 2003Lars Andersson Abstract,,, The aim of this study was to evaluate the results of single-tooth implant treatment in patients where teeth have been lost as a result of trauma. Also, the patients' and professionals' opinions regarding the final outcome of treatment were assessed. Thirty-four patients with 42 lost teeth were evaluated by clinical and radiographic examinations and interviews 2,5 years after treatment. A professional who had not taken part in the treatment evaluated the implant crowns. Central maxillary incisors were the most frequently lost and replaced teeth after trauma (75%) followed by lateral incisors (21%). In patients with incomplete growth, implant treatment was generally postponed until completion of growth. Lack of space was treated by presurgical orthodontics (7%) or by selecting an implant with a reduced diameter (5%). Deficiency of bone was seen in 17% and was treated by bone grafting or local augmentation prior to implant surgery. Patients who had lost two or more teeth after trauma were all subjected to bone grafting. Preservation of roots in the alveolar process seemed to maintain the bone volume enabling better conditions for later implant placement. Forty-one implants (97.6%) were integrated successfully. Complications were few and of minor importance (9.5% before and 12% after cementation of crowns) and could all be managed. No or minimal bone loss was seen. In general, the patients felt that they received good care and that they were well informed about their treatment. Some patients reported that the local anesthesia procedure was not pain-free, but 71% of the patients experienced the treatment as pain-free. For each of the variables (color, shape, height, and size of the crowns), the highest degree of satisfaction was noted in 93,98% of the patients and 91,95% of the single evaluating professional. Given that the patients have finished growth and a careful treatment planning and timing are performed, the functional and esthetical outcome of single-tooth implant treatment today is excellent and can be recommended for replacing tooth losses after trauma in the anterior region of the maxilla. [source] Prospective study of complier individuals under periodontal maintenance therapy: analysis of clinical periodontal parameters, risk predictors and the progression of periodontitisJOURNAL OF CLINICAL PERIODONTOLOGY, Issue 1 2009Telma Campos Medeiros Lorentz Abstract Aim: This prospective study aimed to evaluate the progression of periodontitis and the influence of risk variables among individuals attending a programme of periodontal maintenance treatment in an academic environment. Material and Methods: A total of 150 individuals diagnosed with chronic moderate-advanced periodontitis, and who had finished active periodontal treatment, were incorporated into the periodontal maintenance therapy. Social, demographic and biological variables of interest from subjects were collected at quarterly recalls, over a 12-month period. The effect of variables of interest and confounding on the periodontal status and progression of periodontitis was tested by univariate and multivariate logistic analysis. Results: A total of 130 subjects (86.7%) showed stable periodontal status, whereas 20 subjects (13.3%) presented periodontitis progression. Twenty-eight subjects (18.66%) presented tooth loss that resulted in a total of 47 lost teeth (1.38%). Diabetes was not found to be associated with periodontitis progression (p=0.67). Smoking was significantly associated with a greater progression of periodontitis (OR=2.7, 95% CI 1.01,7.22). Conclusions: Periodontal maintenance programmes in academic environment can stabilize the periodontal condition obtained after active periodontal therapy as well as control the action of risk variables for the progression of periodontitis. [source] Systemic disorders in patients with periodontal diseaseJOURNAL OF CLINICAL PERIODONTOLOGY, Issue 4 2003Maria Lagervall Abstract Background, aims: Over the past 10 years several studies have been published pointing towards a relationship between periodontal disease and various systemic disorders or diseases. The purpose of this retrospective study was to investigate the occurrence of self-reported systemic disorders in patients referred to a specialist clinic for periodontal treatment and to explore possible relationships between general health and periodontal disease severity in this population. Material and Methods: Data were collected from the dental records and the health questionnaires of 1006 subjects. Stepwise multiple linear regression analyses were adopted to calculate correlations between systemic disorders as independent variables and number of remaining teeth and the relative frequency of periodontal pockets of 5 mm or more, respectively, as the dependent variable. Results: The number of remaining teeth was significantly and positively correlated to the presence of cardiovascular disease, diabetes and rheumatoid disease after adjustment for age, sex and smoking. The relative frequency of diseased sites, however, was not significantly correlated to any one of the investigated systemic health disorders. Conclusion: No significant associations between investigated systemic disorders and periodontal disease severity were found if the relative frequency of deep periodontal pockets was used as the clinical parameter for periodontal disease severity. However, cardiovascular disease, diabetes and rheumatoid disease were found to be significantly correlated to number of lost teeth, which may represent one aspect of periodontal health. This result held true in nonsmokers only. Zusammenfassung Hintergrund: Während der letzten 10 Jahre wurden zahlreiche Studien publiziert, die auf einen Zusammenhang zwischen Parodontitis und verschiedenen systemischen Störungen und Erkrankungen hinweisen. Zielsetzung: Feststellung der Häufigkeit von selbst angegebenen systemischen Erkrankungen bei Patienten, die an eine parodontologische Spezialklinik zur Parodontitistherapie überwiesen worden waren, in einer retrospektiven Studie und Untersuchung möglicher Zusammenhänge zwischen allgemeiner Gesundheit und dem Schweregrad parodontaler Erkrankungen in dieser Bevölkerungsgruppe. Material und Methoden: Die Daten wurden aus den Behandlungsakten und Gesundheitsfragebögen von 1006 Personen gewonnen. Eine schrittweise multiple lineare Regressionsanalyse wurde verwendet, um Korrelationen zwischen systemischen Erkrankungen als unabhängigen Variablen und der Zahl verbliebener Zähne bzw. der relativen Häufigkeit parodontaler Taschen 5 mm als abhängigen Variablen zu berechnen. Ergebnisse: Nach Korrektur für Alter, Geschlecht und Rauchen war die Zahl verbliebener Zähne signifikant positiv mit Herz-Kreislauf-Erkrankungen, Diabetes und rheumatischen Erkrankungen korreliert. Die relative Häufigkeit erkrankter Stellen war allerdings mit keiner der untersuchten systemischen Erkrankungen korreliert. Schlussfolgerung: Wenn die relative Häufigkeit tiefer parodontaler Taschen als Maß für den Schweregrad parodontaler Erkrankung gewählt wurde, ließ sich keine Assoziation zwischen den untersuchten systemischen Erkrankungen und dem Parodontitisschweregrad zeigen. Allerdings waren Herz-Kreislauf-Erkrankungen, Diabetes und rheumatischen Erkrankungen signifikant mit der Zahl verlorener Zähne korreliert, die einen Aspekt parodontaler Gesundheit repräsentieren. Dieses Ergebnis ergab sich aber nur für Nichtraucher. Résumé Références et buts: Au cours des 10 dernières années, plusieurs études ont été publiées pour souligner une relation entre la maladie parodontale et diverses désordres ou maladies systémiques. Cette étude rétrospective se propose de rechercher l'apparition de désordres systémiques racontés par des patients adressés à une clinique spécialisée pour traitement parodontal et d'explorer de possibles relations entre la santé générale et la sévérité de la maladie parodontale dans cette population. Matériel et Méthodes: Les données furent récoltées des dossiers dentaires et des interrogatoires médicaux de 1006 sujets. Une analyse de régression multiple linéaire échelonnée a été utilisée pour calculer les corrélations entre les désordres systémiques en tant que variables indépendantes et le nombre de dents restantes et la fréquence relative de poches parodontales d'au moins 5mm, respectivement, comme variable dépendante. Résultats: le nombre de dents restantes était significativement et positivement corréléà la présence de maladies cardiovasculaires, de diabète et de maladie rhumatoïde après ajustement pour l'âge, le sexe, et le tabagisme. La relative fréquence de sites malades, cependant, n'était corrélée à aucun des désordres systémiques étudiés. Conclusion: Aucune association significative entre les désordres systémiques étudiés et la sévérité de la maladie parodontale ne fut trouvée lorsque la fréquence relative de poches parodontales profondes était utilisée comme paramètre clinique pour définir la sévérité de la maladie parodontale. Cependant, une maladie cardio-vasculaire, le diabète, une maladie rhumatoïde sont corrélées significativement au nombre de dents perdues qui peut être représentatif d'un aspect de santé parodontale. Ces résultats n'étaient valables que chez les non fumeurs. [source] Variation in dental wear and tooth loss among known-aged, older ring-tailed lemurs (Lemur catta): a comparison between wild and captive individualsAMERICAN JOURNAL OF PRIMATOLOGY, Issue 11 2010Frank P. Cuozzo Abstract Tooth wear is generally an age-related phenomenon, often assumed to occur at similar rates within populations of primates and other mammals, and has been suggested as a correlate of reduced offspring survival among wild lemurs. Few long-term wild studies have combined detailed study of primate behavior and ecology with dental analyses. Here, we present data on dental wear and tooth loss in older (>10 years old) wild and captive ring-tailed lemurs (Lemur catta). Among older ring-tailed lemurs at the Beza Mahafaly Special Reserve (BMSR), Madagascar (n=6), the percentage of severe dental wear and tooth loss ranges from 6 to 50%. Among these six individuals, the oldest (19 years old) exhibits the second lowest frequency of tooth loss (14%). The majority of captive lemurs at the Indianapolis Zoo (n=7) are older than the oldest BMSR lemur, yet display significantly less overall tooth wear for 19 of 36 tooth positions, with only two individuals exhibiting antemortem tooth loss. Among the captive lemurs, only one lemur (a nearly 29 year old male) has lost more than one tooth. This individual is only missing anterior teeth, in contrast to lemurs at BMSR, where the majority of lost teeth are postcanine teeth associated with processing specific fallback foods. Postcanine teeth also show significantly more overall wear at BMSR than in the captive sample. At BMSR, degree of severe wear and tooth loss varies in same aged, older individuals, likely reflecting differences in microhabitat, and thus the availability and use of different foods. This pattern becomes apparent before "old age," as seen in individuals as young as 7 years. Among the four "older" female lemurs at BMSR, severe wear and/or tooth loss do not predict offspring survival. Am. J. Primatol. 72:1026,1037, 2010. © 2010 Wiley-Liss, Inc. [source] Rationale for esthetic tissue preservation of a fresh extraction socket by an implant treatment concept simulating a tooth replantationDENTAL TRAUMATOLOGY, Issue 1 2010Georgia Trimpou A soft-tissue recession must be avoided, whether it is due to a compression of the peri-implant soft-tissue caused by an over-dimensioned restoration in the cervical collar of the provisional crown or to a too small dimensioned sulcus former. A simulation of the exact dimension of the lost tooth , especially on the cervical part of the new provisional restoration , is expected to preserve all relevant information and allows the design of a naturally looking emergence profile. Based on theoretical considerations and a case report, the authors intend to demonstrate that a near-naturally dimensioned sealing of the dento-gingival soft-tissue collar may initiate a tissue-maintaining healing process, similar to a tooth replantation. The natural dental crown, connected to an implant instead of the root, is applied for a tight sealing of the wound. If due to traumatic impact the tooth is no longer available, a naturally dimensioned crown restoration will serve as an alternative wound sealant. [source] |
