Combined Surgical and Nonsurgical EndodonticTherapy in the Treatment of Dens InvaginatusType 3: A Case Report

摘要

An accurate understanding of the morphology of the root canal system is a prerequisite for successful root canal treatment. Invaginated teeth have a complex root canal configuration that cannot be instrumented effectively. Correct diagnosis and treatment planning are fundamental to treatment of dens invaginatus. Periapical surgery is indicated in cases where a nonsurgical approach fails. A case of dens invaginatus type 3 in a maxillary lateral incisor with a periapical lesion and its successful treatment by these combined methods is reported.
