A Case Report on Maxillary Canine Management of a Type II Dens Invaginatus with an Open Apex and a Large Periapical Lesion


Busch proposed the phrase “dens in dente” in 1897, alluding to the radiographic appearance of a tooth inside another tooth. Hallet created the now popular name dens invaginatus in 1953. The instance of a type II Dens invaginatus involving a maxillary left canine and a sizable chronic periapical lesion that was treated with traditional endodontic care following ultrasonic excision of the invaginated tissue is highlighted in the current research. To more effectively clean and instrument the necrotic root canal system, these tissues were removed. In fact, a cone beam computed tomography examination revealed a clear contact between the main root canal pulp and the dens invaginatus. A dense and hermetic root filling was visible on a post-operative radiography inspection, but unfortunately, an apical deficit from the excessive use of collagen matrix was also visible.
