Isolated impacted supernumerary teeth are quite rare, but they can be seen associated with several syndromes such as cleidocranial dysostosis or Gardner's syndrome. This article aims to discuss a case of sequential formation of supernumerary teeth with no other associated disease or syndrome. A 17-year-old Iranian male with 8 impacted supernumerary teeth was referred to the department of pediatric dental clinic at Shahid Beheshti Medical University in Tehran with a history of several impacted unerupted teeth. Repeated and periodical clinical and radiographic examinations revealed newly formed teeth buds in unusual dental ages. All extra teeth were associated with generalized enamel hypoplasia to some degree on their relative permanent adjacent teeth. The patient did not have any record of a systemic disease or any syndromic condition to relate his dental problem to. This rare condition involved repeated and continued formation of extra teeth out of the normal numbers and dental age evident in serial radiographs.
孤立的埋伏多生牙相当罕见，但可见于多种综合征，如锁骨颅骨发育不全或加德纳综合征。本文旨在讨论一例无其他相关疾病或综合征的多生牙序贯形成病例。一名17岁的伊朗男性，有8颗埋伏多生牙，因有几颗埋伏未萌出牙齿的病史，被转诊至德黑兰沙希德·贝赫什提医科大学儿童牙科诊所。反复的定期临床和影像学检查发现，在异常牙龄时有新形成的牙蕾。所有额外牙齿在相对应的恒牙邻牙上均有一定程度的广泛性釉质发育不全。该患者没有任何全身性疾病记录或任何综合征情况可将其牙齿问题与之关联。这种罕见情况表现为在连续X线片上明显出现超出正常数量和牙龄的额外牙齿反复持续形成。
