Abstract

Background:  The aim of this study was to establish radiographic criteria for early diagnosis of cystic changes in dental follicles associated with impacted third molars and thereby prevent the development of a pathological cyst and its associated complications.  Material and method: This case control study was performed involving 10 cases of impacted third molars with follicle size measuring <2mm and 6 controls with follicle size measuring >3mm, as measured on panoramic radiographs, followed by histopathologic evaluation of the follicles for cystic changes. Result: 55% of follicles associated with impacted third molars, with pericoronal radiolucency less than 2mm actually showed presence of stratified squamous epithelium consistent with a dentigerous cyst. Discussion: On the basis of the results obtained in this study, it was concluded that a pericoronal radiolucency associated with impacted third molar and measuring less than 2 mm in the greatest dimensions should be considered as a potential source for the development of a dentigerous cyst when seen in an OPG.
