Abstract Introduction: Some of periapical lesions could be observed in a radiograph but the exact diagnosis is reach after microscopic evaluation. Unfortunately, in many cases periapical lesions are not diagnose because lack of a radiograph and then the dentist may pull the lesion out completely or incompletely. In this situation remains of the lesion can creat next problems. Objective: Determine frequency of periapical lesions among extracted teeth and classify them according to microscopic evaluation. Materials and Methods: This is a cross- sectional study. It was done in dental’s offices and clinics in Rasht during 8 weeks, forty two lesions were collected among 5900 extracted teeth. The information was recorded and the lesions were sent within formalin10% to Pathology Laboratory in Poursina Hospital. The lesions were sliced by microtome, Stained (H and E), and then they were observed by a pathologist. The lesions were classified and statistical analysis was done by EPI calculator and SPSS 11.5. Results: 42 teeth (0.71%) had periapical lesions among 5900 extracted teeth. After microscopic evaluation the lesions were classified as periapical granuloma (57.14%), periapical cyst (33.33%) and other lesions (9.53%). In this study the frequency of the lesions was similar in both sex, and patients often were between 3rd to 5th decades of their life. The must frequent location of the lesions in the jaw was in the posterior of maxilla, posterior of mandible, anterior of maxilla and anterior of mandible consequently. Conclusion: Almost there are seven periapical lesions among 1000 extracted teeth. Although the frequency of periapical lesions seems to be infrequent, all the periapical lesions should be sent to laboratory because lesions like mural ameloblastoma and traumatic bone cyst might be needed different treatment.
