Cysts of the periapical region in children: A 19-year institutional review

Abstract

Background: There are very few studies that have been done specifically on cysts of the periapical region in children. Aim: To do a retrospective analysis of specimens received as cysts of periapical region in children. Design: A Total of 3142 oral biopsies received over a period of 19 years (1987- 2005) at the department of oral pathology A.B. Shetty Memorial Institute of Dental Sciences, Derelakatte, Mangalore, India were retrieved and all paediatric oral biopsies were further histopathologically analyzed. Results: Our study found that 39% of the total paediatric oral biopsies received were cysts and the commonest cyst was radicular cyst (43.3%) followed by dentigerous cyst (20.6′0), odontogenic keratocyst (8.6′0) and lateral periodontal cyst (1.7%) which was different from most reported studies. Conclusion: Radicular cyst is the commonest cyst reported in this study which is different from most reported studies probably because of the type of biopsies received at our institute.
