1 J Korean Academy of Advanced General Dentistry 2014;3:29-33 ABSTRACT Endodontic Treatment of 2 Maxillary Lateral Incisors with Dens Invaginatus; 2 Case Reports Jaemin Lee, Kee-Deog Kim, Bock-Young Jung, Wonse Park, Kang-Hee Lee, Hye-Jeong Park, Nan-Sim Pang Department of Advanced General Dentistry, College of Dentistry, Yonsei University 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. Key words : Dens invaginatus, Endodontic treatment, Maxillary lateral incisor..
