Dens invaginatus is a dental developmental abnormality caused by an infolding of the enamel organ into the adjacent dental papilla before the calcification of the dental tissues. The clinical presentation of dens invaginatus varies according to its severity, from mild forms, in which we might find a deeper than normal cingulum pit, to severe cases, in which there is a pronounced infolding reaching the apical foramen. The very nature of the invagination favours the contamination from the oral environment to the pulp space and the onset of caries. Therefore, patients might present with symptoms or signs of pulpitis and/or apical periodontitis. The aim of this paper is to present the successful endodontic and restorative management of a conoid shaped upper lateral incisor, affected by dens invaginatus type IIIA.

IIIA 型内陷圆锥形牙齿的牙髓和美学管理。

Dens invaginatus 是由于牙釉质器官在牙齿组织钙化之前内折叠到相邻牙乳头中而引起的牙齿发育异常。内陷窝的临床表现根据其严重程度而有所不同，从轻微的形式，我们可能会发现比正常的扣带窝更深，到严重的情况，其中有一个明显的内折叠到达顶端孔。内陷的本质有利于从口腔环境到牙髓空间的污染和龋齿的发生。因此，患者可能会出现牙髓炎和/或根尖周炎的症状或体征。本文的目的是介绍受内陷窝 IIIA 型影响的圆锥形上侧切牙的成功牙髓和修复治疗。
