Managing Perforating Internal Root Resorption in Mature Incisor with Laser-assisted Regenerative Endodontic Procedures.

Introduction: This report presented the successful application of laser-assisted regenerative endodontic procedures (REPs) in managing perforating internal root resorption (PIRR) in a mature incisor.

Methods: A 24-year-old female with a history of trauma was referred for treatment of her maxillary anterior tooth. Clinical examination and cone-beam computed tomography imaging revealed that tooth #9 had PIRR with a lateral inflammatory lesion and thin canal walls. Consequently, a novel laser-assisted REPs was performed to treat PIRR.

Results: Three-year follow-up showed apical healing, cessation of resorption, and hard tissue formation within the resorptive defect.

Conclusions: This outcome demonstrated the efficacy of laser-assisted REPs for managing infection in mature teeth with PIRR, where bleeding from the apical foramen could be supplemented by blood flow through the lateral wall perforations, thereby enhancing the outcome of REPs.
