GAMARRA, José et al. Frequency of the position, inclination and degree of surgical difficulty of mandibular third molars in patients attending at the School of Dentistry of the National University of Asunción. Mem. Inst. Investig. Cienc. Salud [online]. 2022, vol.20, n.1, pp.22-29. ISSN 1812-9528.  https://doi.org/10.18004/mem.iics/1812-9528/2022.020.01.22.

The position a mandibular third molar can adopt is unpredictable in most cases. To facilitate the analysis of the position and inclination of third molars, authors such as Pell-Gregory and Winter established a classification of these teeth to guide the most appropriate surgical technique for each situation. The objective was to determine the frequency of the position, inclination and degree of surgical difficulty in mandibular third molars. The study was descriptive, retrospective, cross-sectional, and observational. Panoramic radiographs of patients who attended the School of Dentistry of the National University of Asuncion between 2018 and 2020 were part of the study. A total of 220 panoramic radiographs were included in the study, 120 (54.5%) corresponded to women and 100 (45.4%) to men, the age group from 18 to 28 years old had the most participation with 134 (61%) radiographs. A frequency in position A class II of 141 (36.6%) was evidenced, while in terms of the inclination the mesioangular was the most frequent, 174 (45.5%) and in terms of the degree of surgical difficulty, minimal to moderate difficulty was observed. A high frequency of position A class II, mesial inclination was evidenced in all the radiographs analyzed.
