Dens invaginatus (DI) is one of the most common developmental anomalies observed in maxillary lateral incisors. An early diagnosis requires thorough clinical knowledge, advanced radiographic evaluation as well as the use of cone beam computed tomography (CBCT) and dental operating microscope (DOM), dictates the successful endodontic management of such teeth. A total of 7 cases with (DI) in maxillary lateral incisors were collected from dental practitioners worldwide, analysed and reported in the present case series. Our aim was to analyse and understand the various morphological patterns of DI in maxillary lateral incisors with their varied treatment protocols employed worldwide. This article illustrates the aberrant morphological patterns and the diverse treatment protocols followed by the clinicians worldwide. The use of biomaterials enhances post-operative healing. Further, a modification in the existing classification has been proposed in this report which would enable the clinicians to easily diagnose, categorise and effectively manage DI. The different treatment protocols employed for the management of DI has been discussed and the use of CBCT and DOM in identifying and managing the anatomical variation of DI were emphasised.
