Prevalence Of Impacted Third Molars Research Articles

Estudo dos Terceiros Molares numa População de Consulta Clínica em Gandra

ObjectivesTo establish the prevalence of impacted third molars in an asymptomatic population and characterize the impaction and its sub-types in this population. Material and methodsBy the analysis of orthopantomograms, and using a descriptive protocol, in witch the confidentiality of data was respected, a clinical-radiological study of individuals that have been assisted in the dental clinic of C.E.S.P.U. in Gandra, for the first time, during the year 2005 was undertaken, and data was obtained regarding the presence or absence of the third molars on the arcades. The tooth was defined as being ectopic, impacted, semi-impacted, extracted or absent. In the cases where the third molar was observed on the arcade or where an impaction or semi-impaction was detected its relative position was recorded: horizontal, vertical, mesioangular, or distoangular. ResultsWe can evidence that the ages with bigger percentages of existing individuals in the sample are: of the 16 to the 25 years. The positioning of the impacted third molars most frequent is the ones that present a normal situation of eruption with a vertical positioning. Most of the individuals does not present any complication of the inclusion. ConclusionsThe third molar ones although to be gifts in the great majority of the population, only in a small percentage if present in its all. The dental caries of the adjacent tooth is associated with the inclination and the position of the third molar ones. The relation between the third molar and inferior alveolar nerve are, in some cases, very next.

A study to determine the prevalence of impacted third molars among patients seen in Dar es Salaam Dental Clinics

World-wide, ameloblastoma have been discussed in relation and modalities of treatment. In Tanzania, case,s of ameloblastoma are seen but no data is available to quantify the magnitude of the disease within the community. The present study aims at describing the occurrence, sex, age and regional distribution of ameloblastoma cases seem from June 1989 to June 1997 in Tanzania.' The pathology records in the Department of Oral Surgery and Pathology, Faculty of Dentistry, Muhimbili University College of Health Sciences, were examined for all cases of oral and maxillofacial tumours occuring over that period. The ameloblastoma cases were analysed for age, sex, anatomical distribution, clinical features, regional distribution and treatment methods. Only cases confirmed by tissue biopsy were included in the study. Out of 384 oral and maxillofacial tumours, 18.2% (70) were ameloblastoma. Males (58.6%) were affected more than females (41.4%). Most of the ameloblastomas were found in the mandible (97.1 %) in the molar/angle regions (57.1 %) and 20% were in the incisors/canine areas and occurred in the third and fourth decades of life. Fourteen regions out of twenty regions in Tanzania recorded some cases of ameloblastoma, but majority of the cases were from Dar es Salaam (29.6%), Mbeya (18.5%), and Kilimanjaro regions (9.3%). Ameloblastoma in this study occurs predominately in the molar/angle and incisors/canine areas of the mandible with men being more affected than women. Radical excision entailing partial/total mandibulectomy or maxillectomy gave better results.
