Abstract

With the development of three-dimensional (3D) imaging, conventional x-ray examinations of the maxillary canines begin to be performed using computed tomography (CT). Recently, cone-beam computed tomography (CBCT) has become an alternative to traditional CT in the diagnosis and treatment planning of affected teeth. Objectives: to determine the main features of the affected canines of the upper jaw and their effect on the adjacent teeth using CBCT. Materials and methods. 68 patients (79 affected maxillary canines) were examined (30.9% men and 69.1% women) at average age 32.7±2.44 years. Unilateral canine lesions were observed in 57 (83.8%) patients, bilateral — in 11 (16.2%) patients. The affected canines on the left — 57.0%, on the right — 43.0%. In 38 (55.9%) cases, canines were affected as a result of trauma, in 30 (44.1%) cases — due to caries. Results. Palatal localization prevailed. Out of 51 canines with resorption, soft resorption was determined in 29 cases, moderate — in 22 cases. In 64.6% of cases, resorption of adjacent teeth took place — with 33 lateral incisors, 17 central incisors and with the first premolar. With the buccal position, resorption was observed in 10 (19.6%) cases, with the palatal and central position in 39 (76.5%) and 2 (3.9%) cases, respectively. In the palatal position, root resorption exceeded that in the buccal and central position by 3.9 times (p<0.01) and 19.6 times (p<0.001). Root rupture was visualized in 44.3% of cases. Conclusion. CBCT made it possible to assess the degree of resorption of the lateral roots of the incisors adjacent to the affected maxillary canines. The method contributes to a more accurate representation of adjacent root resorptions, slopes and depth of the affected canines.
