초록
Dens invaginatus is a developmental variation resulting from the infolding of the dental papilla before calcification of the dental tissue. Permanent maxillary lateral incisors are most commonly affected. The most widely used classification system for dens invaginatus was described by Oehlers. The purpose of this paper was to describe treatments of 2 cases on Type II dens invaginatus with open apex. In the first case, the invaginated barrier was removed, apexification and nonsurgical endodontic treatment was performed. At the 8-month follow-up, no clinical symptoms or radiographic apical lesion were observed. In the second case, because of the morphologic variation, it was unable to clean and shape the root canal system. Thus, apical surgery was performed. After 5 months, no signs of sinus tract or radiographic apical lesion was observed. In these cases, satisfactory clinical and radiographic outcomes were observed. It is important to know about root canal anatomy for successful endodontic treatment of dens invaginatus.
Abstract
Dens invaginatus is a developmental variation resulting from the infolding of the dental papilla before calcification of the dental tissue.
