This research determined the characterization of the impaction of permanent mandibular second molars in patients treated at the dental teaching clinic of the Universidad Privada Juan Pablo II in 2017. Materials and Methods: This was an observational study with a descriptive, cross-sectional design and a retrospective type. A total of 200 panoramic radiographs of patients over 15 years of age, of both genders, treated in 2017, were used. The representative sample consisted of 111 panoramic radiographs. Data collection and statistical analysis were performed using SPSS version 21.0. Results: The frequency of impaction of permanent mandibular second molars was 9.9%. The radiographic angulation according to the Occlusal Plane Angle (APO) was 130.64 ± 10.337; the Interplanar Occlusal Angle (AIP) was 42.91 ± 6.503, while the Intermolar Angle (AIM) was 34.91 ± 6.348. The impaction inclination of the mandibular second molars was mesioangular, and radiographic pathologies of adjacent structures to the impacted second molars were observed. Bone defects were found in 18.21% of cases, and carious lesions also accounted for 18.21%. The gender with the highest impaction frequency was male, with 54.5%, while female accounted for only 45.5%. The most impacted mandibular side was the right, with 72.7% (8), while the left had 27.3% (3). Conclusion: The prevalence of impaction of permanent mandibular second molars is low.
