Buccal Bifurcation Cyst in a 7‐Year‐Old: Surgical Management and 14‐Month Follow‐Up

Abstract

The buccal bifurcation cyst (BBC) is a paradental cyst that typically presents on the buccal aspect of mandibular permanent first molars in children 6 to 11 years of age. Histopathologic features are non-specific and closely resemble other inflammatory odontogenic cysts. The aim of this article is to report a case of a BBC and to review the management of such lesions.A 7-year-old white male, complaining of lower right tooth pain and swelling, presented to the Nationwide Children's Hospital Dental Clinic. A clinical examination revealed no caries and swelling localized to the area approximating tooth #30 with a 15-mm probing depth on the buccal aspect. Radiographs revealed a radiolucency involving the bifurcation and root area of tooth #30, accompanied by the distal displacement of unerupted tooth #31. Therapy consisted of a simple surgical enucleation of the cyst.A microscopic evaluation revealed a chronically inflamed cyst lined by a non-keratinized stratified squamous epithelium. The immediate postoperative course was uneventful. At 14 months postoperatively, the development of teeth #30 and #31 was noted as normal. Probing depths around tooth #30 were <or=4 mm, tooth #31 was no longer displaced, and no recurrence was detected.The simple surgical enucleation of the BBC provided good short- and long-term outcomes without compromising the development of associated molars.
