Degree of surgical difficulty of lower third molars evaluated in panoramic radiographs at the Surco CEDIXS X-Ray Diagnosis Center, 2023
(Universidad Privada Norbert Wiener, 2023-12-07) Durand Andrade, Flor Rosario; Ascanoa Olazo, Jimmy Antonio
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.

Relationship between the morphology of the mandibular canal and the lower third molars in patients treated at the radiology service of the Guillermo Almenara Irigoyen National Hospital from July 2018 to December 2018 - Lima. Peru.

Objective: To relate the morphology of the mandibular canal with the characteristics of the lower third molars in patients treated at the Radiology Department of the Guillermo Almenara Irigoyen National Hospital from July to December 2018. Materials and Methods: This was an observational relational study, cross-sectional, and retrospective in design. A total of 320 panoramic radiographs from patients over 18 years of age, of both genders, who were treated between July and December 2018, were used. The sample consisted of 150 panoramic radiographs. Results: The average diameter of the mandibular canal was found to be 3 mm. The distance between the mandibular canal and the alveolar ridge on the right side was 7 mm in the mesial zone and 6.4 mm in the distal zone. On the left side, the mesial zone distance was 7.1 mm, and the distal zone distance was 6.6 mm. The frequency of the third molar position on the right side was mesioangulated in 32% and horizontal in 20%. On the left side, the mesioangulated position represented 30.6%, and the horizontal position was 20%. The frequency of the degree of eruption of the right third molar was 49.3% erupted, 46% impacted, and 4.7% absent. On the left side, 49.3% were erupted, 48.7% impacted, and 2% absent. Conclusion: There is a relationship between the morphology of the mandibular canal and the lower third molars.
