Resumo

Buccal bifurcation cyst (BBC) is an uncommon inflammatory odontogenic cyst that predominantly affects the buccal aspect of partially erupted mandibular molars in children. Because its histopathological features are nonspecific, diagnosis relies on careful clinicopathological correlation.This report describes two pediatric cases of BBC associated with mandibular second molars, including a rare bilateral presentation. Both patients presented with buccal swelling, and imaging revealed well-defined radiolucent lesions associated with vital mandibular molars. Conservative surgical enucleation with preservation of the involved teeth was performed in both cases. Histopathological examination demonstrated cystic lesions lined by non-keratinized stratified squamous epithelium with chronic inflammatory infiltrate, confirming the diagnosis when correlated with the clinical and radiographic findings. No recurrence was observed during follow-up, and spontaneous eruption of the affected teeth occurred. These cases emphasize the importance of considering BBC in the differential diagnosis of radiolucent lesions associated with vital, fully or partially erupted mandibular molars in children and adolescents. Early recognition and conservative management allow preservation of the involved teeth and result in favorable clinical outcomes.
