The purpose of this research was to determine the relationship between retention cysts and dentoalveolar pathologies using digital panoramic radiographs in Lima, 2018. This was an observational, descriptive, and cross-sectional study. The sample consisted of 183 digital panoramic radiographs from patients who visited the stomatological imaging center to request these radiographs at the recommendation of their treating dentist. A representative sample of 183 digital panoramic radiographs was determined through simple random sampling for proportions. The following variables were collected: retention cyst, dentoalveolar pathologies, periodontal disease, root canal treatment, pulp pathology, sex, and age. The data were processed using SPSS version 24.0. Statistical significance was determined using the Chi-square test to evaluate relationships between variables with a significance level of p<0.05. The results revealed a significant presence of retention cysts in the right maxillary sinus (15.3%). Retention cysts were more frequently observed in females and adolescents. Among patients, 9.4% with root canal treatments, 13.6% with pulp pathology, and 22% with periodontal disease presented retention cysts. A statistically significant relationship was found between the presence of retention cysts and pulp pathology and root canal treatment, but not with periodontal disease.

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.
