Background: The extraction of wisdom teeth without a correct diagnosis and planning can lead to diverse complications, such as injury to the structures within inferior alveolar canal, affecting the quality of life of the patient. Objective: To know the proximity of third molar roots to the inferior alveolar canal in cone beam computed tomography scans from the Radiology Service of Finis Terrae University between the years 2019 to 2022. Materials and methods: An observational descriptive cross-sectional study was carried out. 211 cone beam computed tomography scans obtained from the Radiology Service of Faculty of Dentistry of Finis Terrae University between the years 2019 and 2022 database were analyzed, which were acquired through the equipment Kavo OP 3D Pro. To classify the proximity of lower third molar roots to the inferior alveolar canal the Tanaka classification (Type I, II, III, IV, V) was used, considering gender and whether the tooth was located on the right or the left side. Results: Of the 211 CBTs analyzed, only a total of 70 CBCTs were selected according to the inclusion and exclusion criteria. 68.6% are female and 31.4% are male. In general, the most prevalent type according to the Tanaka classification was type III with 40.5%. When analyzed by side, both the right and left sides showed a higher prevalence of type III with 31.7% and 44.6% respectively. Discussions and conclusions: A high prevalence of cases where the roots of the wisdom tooth contact the upper wall of the inferior alveolar canal were evident, confirming the existence of proximity between both.
