Supernumerary teeth--teeth in excess of the normal dental complement--are usually asymptomatic, and their presence is detected incidentally on radiographs. Mesiodentes are the most common type of supernumerary teeth, followed by maxillary distomolars, maxillary lateral incisors, mandibular fourth molars, and maxillary premolars. Bilateral occurrence of supernumerary teeth is rare. When supernumerary teeth do occur bilaterally, they are most often associated with a syndrome such as Gardner syndrome or cleidocranial dysostosis. This article presents case reports of 4 nonsyndromic patients with different forms of bilateral supernumerary teeth: bilateral mesiodentes, bilateral paramolars, bilateral distomolars, and bilateral parapremolars. The supernumerary teeth were managed by extraction or clinical and radiographic monitoring.
多生牙——超过正常牙列数量的牙齿——通常没有症状，其存在往往是在影像学检查时偶然发现的。正中牙是最常见的多生牙类型，其次是上颌第三磨牙、上颌侧切牙、下颌第四磨牙和上颌前磨牙。多生牙双侧发生的情况很少见。当多生牙双侧出现时，它们最常与诸如加德纳综合征或锁骨颅骨发育不全等综合征相关。本文介绍了4例非综合征性双侧多生牙不同形式的病例报告：双侧正中牙、双侧磨牙旁牙、双侧第三磨牙和双侧前磨牙旁牙。多生牙通过拔除或临床及影像学监测进行处理。
