Análise de lesões de furca em molares por tomografia computadorizada de feixe cônico

Abstract

Furcation lesions are characterized by bone resorption and attachment loss into the interradicular space. Accurate diagnosis of periodontal disease affecting the furcation area requires periodontal examination and imaging. Cone beam computed tomography (CBCT) is capable of generating accurate and reliable submillimeter resolution images in all space dimensions and plays a role in the evaluation and treatment planning of molars with furcation (FL) damage. PROPOSITION: Evaluate tomographic aspects of furcation lesions, measure attachment loss and rank the FL. METHODOLOGY: retrospective observational crosssectional study, CBCT scans were analyzed with a sample consisting of 560 teeth of patients of both sexes, aged between 30 and 70 years. Bone loss in height/width/depth of the interradicular area was analyzed, based on this measurement, it was classified into degrees I, II and III and its prevalence was evaluated according to its distribution by sex and age, and the most affected teeth. RESULTS: FL grade II were the most observed in both upper and lower molars. The group of teeth most affected by FL were the upper molars, most frequently in females in group I (41-50 years), classified as grade II in buccal and distal furcations and grade I in mesial furcations. In lower molars, the highest frequency was FL grade II in females in groups 1 (30- 40 years) and 2 (41-50 years) and, FL grade III in males in group III (51-70 years). CONCLUSION: CBCT proved to be effective for the diagnosis of FL and may contribute to an accurate diagnosis and consequent better treatment plan.
