A case history of an ectopically erupting mandibular left first permanent molar is described. Most notable are the unusual findings of a missing mandibular left second premolar and an epithelial cyst and a horizontally impacted mandibular left second permanent molar. A unique treatment plan called for the extraction of the mandibular second primary molar, excision of the cyst, and removal of the mandibular left second and third molars. In hindsight, other procedures might have served the patient better.
描述了一例下颌左侧第一恒磨牙异位萌出的病例史。最值得注意的是下颌左侧第二前磨牙缺失、上皮囊肿以及下颌左侧第二恒磨牙水平阻生这些不寻常的发现。一个独特的治疗方案要求拔除下颌第二乳磨牙、切除囊肿以及拔除下颌左侧第二和第三磨牙。事后看来，其他治疗方法可能对患者更有益。
