Treatment of dens invaginatus: 4-year follow-up

Abstract

Abstract Dens invaginatus is a rare developmental defect that can complicate the proper diagnosis and treatment of teeth. The most common location of an invaginated tooth is the second lateral maxillary incisor, while the least common locations are the mandibular incisors and canines. Due to the complicated anatomy of invaginated teeth, the endodontic treatment of these teeth can present many difficulties. The present case report describes the endodontic treatment of the dens invaginatus – permanent second maxillary lateral incisor with a 4-year clinical and radiologic follow-up.
