CBCT Evaluation and Conservative Management of a Large Periapical Lesion Associated with Dens Invaginatus Type II

This case report illustrated the conservative management of an invaginated type II tooth with a large periapical lesion. This dental malformation is characterized by the complexity of root canal anatomy, which when associated with a periapical lesion complicates the performance of conventional endodontic treatment, hence resulting to the difficulty of obtaining the optimal disinfection of the root canal system, which is an essential element for the success of any endodontic treatment. In the present case report, clinical and radiographic examinations were supplemented by CBCT examination to identify the root canal configuration and the extension of the periapical lesion. Conservative orthograde endodontic treatment was performed by combining mechanical and chemical action. Additionally, active nonsurgical decompression was performed and the follow-up visits revealed a favorable outcome.
