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.

The objective of this study was to determine the surgical difficulty of lower third molars assessed on panoramic radiographs at the X-Ray Surco CEDIXS diagnostic center in 2023. The research was observational, cross-sectional, retrospective, and descriptive. The instrument used for data collection was a form with sections for sex, Winter classification, Pell and Gregory classification, and the Koerner index to assess surgical difficulty. A total of 278 panoramic radiographs were evaluated, and the following results were obtained: 46.04% presented moderate difficulty, followed by 35.61% with minimal difficulty, and 18.35% with high difficulty according to the Koerner index. Regarding the Winter classification, 62.20% of the patients had mesioangular third molar positions, 14.40% had horizontal or transverse positions, 13.70% had vertical positions, and 9.70% had distoangular positions. In the Pell and Gregory classification, class 2 (space availability) predominated with 54.30%, and level 1 (depth) was observed in 52.50%. Conclusion: The evaluation of third molars through panoramic radiographs is essential to complement the clinical diagnosis, choose the appropriate surgical technique, and minimize complications during and after surgery, ensuring favorable outcomes for the patient

Relationship between the location of lower third molars according to Pell & Gregory and their proximity to the mandibular canal according to Ezoddini in panoramic radiographs of patients aged 18 to 50 years treated at the radiological center Ceramax, 2022

The objective of this study was to determine the relationship between the location of lower third molars according to Pell and Gregory and the proximity to the mandibular canal according to Ezoddini in panoramic radiographs of patients aged 18 to 50 years treated at the Ceramax Radiological Center in 2022. Methodology: A cross-sectional, observational, correlational, and retrospective study was conducted with a sample of 150 panoramic radiographs and a total of 216 lower third molars. A data collection sheet was created to record gender, age group, location according to Pell and Gregory, and proximity to the mandibular canal according to Ezoddini. Results: The most frequent location according to Pell and Gregory was Class I Level A (53.2%), while the most frequent proximity to the mandibular canal according to Ezoddini was "There is contact between the root and the canal" (42.6%). It was determined that there is a statistically significant association (p = 0.000) between both variables. On the other hand, there was no statistically significant relationship between the location of lower third molars according to Pell and Gregory with gender and age group (p > 0.05). However, there was a statistically significant relationship between proximity to the mandibular canal according to Ezoddini with gender and age group (p < 0.05). Conclusion: There is a relationship between the location of lower third molars according to Pell and Gregory and proximity to the mandibular canal according to Ezoddini in panoramic radiographs of patients aged 18 to 50 years treated at the Ceramax Radiological Center in 2022.
