Combined endodontic and periodontal management of trauma-induced tooth resorption: case reports and review of the literature.

The objectives of this article are to report 2 cases of trauma-induced invasive cervical resorption (ICR) treated with surgical and nonsurgical restoration modalities and to review the literature on the clinical effectiveness of these approaches. Both surgical and nonsurgical techniques resulted in successful outcomes for 2 patients with trauma-induced ICR, classified as class 4 in the Heithersay classification and 3Bp in the 3-dimensional classification proposed by Patel et al. In the first case, the inapproachable resorptive lacuna was restored surgically, while in the second case, the large, approachable resorptive lacunae was treated nonsurgically. Treatment included root canal therapy, removal of granulation tissue, and placement of trichloroacetic acid and mineral trioxide aggregate to restore the resorptive lacuna. Follow-up examinations at 24 and 18 months for cases 1 and 2, respectively, indicated no recurrence, demonstrating successful management. Supporting the positive outcomes observed in these 2 clinical cases, the published literature suggests that the use of advanced diagnostic tools and appropriate treatment modalities tailored to each specific case can substantially increase the long-term retention of teeth affected by ICR.
