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.
颊侧分又囊肿(BBC)是一种位于儿童 6 至 11 岁下颌恒磨牙颊侧的牙旁囊肿。组织病理学特征无特异性,与其他炎症性牙源性囊肿非常相似。本文旨在报告一个 BBC 病例,并复习此类病变的处理方法。
一名 7 岁白人男性,因右下牙疼痛和肿胀就诊于全美儿童医院牙科诊所。临床检查未见龋齿,肿胀局限于近似#30 牙的区域,颊侧探诊深度为 15mm。X 线片显示#30 牙的分叉和根部区域出现透亮区,伴有未萌出牙#31 的远中移位。治疗包括囊肿的单纯外科切除。
显微镜评估显示慢性炎症性囊肿,内衬非角化复层扁平鳞状上皮。术后即刻过程无并发症。术后 14 个月,#30 和#31 牙的萌出正常。#30 牙周围的探诊深度<或=4mm,#31 牙不再移位,未发现复发。
BBC 的单纯外科切除可提供良好的短期和长期效果,而不会影响相关磨牙的发育。
