Abstract
OBJECTIVES: The selection of treatment for advanced (classes 3 and 4) invasive cervical resorption (ICR) based on a two-dimensional periapical radiograph is challenging. The purpose of the present study is to describe different treatment approaches for advanced invasive cervical resorption based on cone-beam computed tomography evaluation. MATERIALS AND METHODS: All cases of advanced ICR based on CBCT evaluation in our endodontic department between 2011 and 2016 were included in the study. The dimension, circumferential, and coronal-cervical locations of the entry point of the resorption tissue into the tooth were evaluated. The selected treatment approach for each case was documented, and all the data were summarized and analyzed. RESULTS: Twenty-three cases of advanced ICR were included in the study. Approximately, 74% were diagnosed in stage 4, and 26% were diagnosed in stage 3. The narrow entry point was identified in 43% (10 cases), while in 57% (13) of cases, the entry point was wide. Circumferentially, 70% (16) were located on the proximal side. Coronal-cervically, 43% (10) were located more than 1.5 mm above the crestal bone. All narrow entry point cases were treated using a minimally invasive technique, while different treatment approaches were chosen for cases with a wide entry point. CONCLUSIONS: The present study proposes different treatment approaches for advanced ICR based on CBCT. The CBCT evaluation of the entry point may facilitate choosing the appropriate treatment approach for advanced ICR cases. CLINICAL RELEVANCE: The description of different treatment approaches for advanced invasive cervical resorption based on cone-beam computed tomography evaluation enables the clinician to choose the optimal treatment approach for each advanced ICR case.
