The present study reports a case of a mandibular buccal bifurcation cyst (MBBC) associated with a partially erupted mandibular first molar. The intraoral examination revealed vestibular swelling in the right mandibular permanent first molar region. Panoramic radiography and cone-beam computed tomography (CBCT) showed a well-delimited radiolucent image involving the roots and part of the crown of the right mandibular permanent first molar with bulging and areas of buccal cortical bone resorption. An incisional biopsy was performed and the diagnosis was MBBC. The lesion was surgically removed by enucleation and curettage. Bone repair was observed seven months after the surgical procedure.
本研究报告了一例与部分萌出的下颌第一磨牙相关的下颌颊侧分叉囊肿（MBBC）病例。口腔检查发现右下颌恒第一磨牙区域前庭肿胀。全景X线片和锥形束计算机断层扫描（CBCT）显示，一个边界清晰的透射影像累及右下颌恒第一磨牙的牙根和部分牙冠，伴有颊侧皮质骨膨隆和吸收区域。进行了切开活检，诊断为MBBC。通过摘除术和刮除术将病变手术切除。术后七个月观察到骨修复情况。
