Dentigerous Cyst with Dystrophic Calcifications

The unerupted mandibular posteriors are main sources of odontogenic cysts/tumours as the follicular tissue is active in relation to third molars until middle age (fifth decade). A dentigerous cyst is the second-most common odontogenic cyst associated with mandibular third molars where there is an accumulation of fluid between reduced enamel epithelium and completely formed crown of the tooth. The presence of dystrophic calcifications within the cystic wall is a rare phenomenon, which can mimic the radiopaque components of other odontogenic cysts and tumours, posing a diagnostic challenge. Therefore, this case report aims to highlight the importance of a thorough histopathological evaluation to ensure an accurate diagnosis and guide appropriate management.
