Levantamento sobre a prevalência e o perfil de terceiros molares inferiores impactados associados a condições patológicas nas radiografias panorâmicas da clínica de radiologia da Faculdade de Odontologia da Universidade Federal do Ceará: estudo observacional, retrospectivo e transversal

Abstract

The third molar inferior presents the highest index of inclusion cases, being frequently associated with pericoronaritis, periodontitis, neoplasia and root resorption, making its surgical removal one of the most frequent procedures in dentistry. In this context, it is essential to use radiographic examinations, such as panoramic radiography (PR), since through these it is possible to classify them and establish a surgical planning. In order to carry out a survey on the prevalence of gender and age, position variability and pathological alterations associated with impacted lower third molars, 678 RPs of both genres were selected, with at least one impacted lower third molar, whose second adjacent molars were present, since their presence is necessary to classify the impaction level of the lower third molars. Each RP was analyzed by a previously calibrated examiner (Kappa=0,852). There was a higher prevalence of females and of the mesioangular and horizontal positions, and class II / positions A and B. As for the incidence of pathological alterations, the values obtained were not high, but there was a higher incidence of caries. So, the knowledge of the dental surgeon about the positions and classifications of the lower third molars in the RP, as well as consequent associated pathological alterations, in order to establish a correct diagnosis and clinical conduct becomes fundamental.
