Non‐syndromic bilateral dentigerous cysts with significant root resorption: a case report

Abstract

AbstractDentigerous cysts are the most common developmental odontogenic cysts and are associated with impacted teeth, usually third molars. Bilateral dentigerous cysts are rare and usually occur in patients with a known syndrome, such as cleidocranial dysplasia. In this study, we report a case of bilateral dentigerous cysts with associated significant root resorption in an otherwise healthy 38‐year‐old female patient. The patient presented with left‐sided non‐tender mandibular swelling and mobility of the left mandibular first and second molar teeth. Radiological investigations revealed two large, unilocular, well‐circumscribed, radiolucent lesions involving the impacted lower wisdom teeth. There was extensive root resorption of the lower molars. The patient underwent enucleation of both cysts and extraction of the involved teeth. Histological features were consistent with dentigerous cysts, with both lesions consisting of a fibrous wall lined by non‐keratinizing stratified squamous epithelium. Non‐syndromic bilateral dentigerous cysts are extremely uncommon. This case, with associated significant root resorption, reflects aggressive biological behaviour and shows that commonly encountered lesions can present as a diagnostic challenge, emphasizing the importance of histopathological analysis in the definitive diagnosis and the overall management.
