The objective of this research was to determine the location of the lower third molars according to the Winter classification and the Pell and Gregory classification in panoramic radiographs of patients aged 18 to 50 from the Dental Clinic of the Universidad Privada Norbert Wiener, Lima, 2017. A total of 101 panoramic radiographs of patients aged 18 to 50 from the years 2012-2014 were used; both lower third molars were taken from each panoramic radiograph, and the Winter and Pell – Gregory classifications were applied. Results: The most prevalent location of lower third molars according to the Winter classification was horizontal with 66.3%, mesioangular with 18.8%, and vertical with 12.9%. The location of the lower third molars according to the Winter classification and age group showed that in all three age groups, horizontal, mesioangular, and vertical positions were the most prevalent, respectively. Conclusions: According to the Winter classification, the most prevalent positions were horizontal, mesioangular, and vertical, while according to the Pell and Gregory classification, it was IIB, followed by IB. It was also determined that these positions were the most frequent in both genders and age groups.
