Introduction:- A tooth is supposed to be affected if it is unable to reach the occlusal plane even after 2/3rd of root formation. Distal caries is frequently observed in the mandibular second molar and may result from an impacted tooth if left untreated.

Aim and Objective: - The current research determined (1) the distribution of mandibular 3rd molar impaction (2) the pattern distribution of impaction radiographically (3) the gender distribution of impaction pattern (4) prevalence level of distal caries lesion in mandibular 2nd molar at impaction side.

Materials & method:- A retrospective analysis was done on 989 orthopantomography(OPGs) using Genoray Papaya device and Triana software in the Oral Medicine and Radiology Department at “Goenka Research Institute of Dental Science”. The pattern of impacted teeth was assessed and level of eruption was noted according to Pell and Gregory’s classification. Additionally, carious lesions that were seen in adjacent mandibular second molars were identified and noted.

Results:- A total 267 patients (26.99%) had impacted 3rd molars; 13% of these patients also had distal cervical caries in their 2nd molars. The most common type was mesioangular impaction. Female gender had greatest prevalence of impacted 3rd molar.

Conclusion:- The present investigation gives valuable data about radiographic status of impacted mandibular 3rd molar among patients.
