Buccal Bifurcation Cyst: Two Case Reports and a Literature Review.

Introduction: A buccal bifurcation cyst (BBC) is an uncommon inflammatory odontogenic cyst associated with the permanent mandibular first or second molar in children.

Case Reports: These reports present two cases of BBC and describes the clinical and radiographic features leading to the diagnosis and the treatment of this lesion. Two patients complained of mandibular buccal swelling around the permanent first molar. The diagnosis of BBC in both cases was based on the clinical and radiographic features. In both cases, only enucleation was performed without extracting the involved tooth.

Results: There were no recurrences during follow up. All teeth remained vital and erupted normally.

Conclusion: The most appropriate treatment is usually enucleation of the cyst without extraction of the associated tooth. Therefore, knowledge of the distinct features of BBC is important for diagnosis and appropriate treatment.
