Abstract

The aim of this study was to evaluate root surface alterations in terms of location, length, and depth of root resorption in the gingival, middle, and apical third of the mesial and distal surfaces of the root in healthy and periodontally affected teeth with chronic periodontitis.Teeth diagnosed with differing severity of chronic periodontitis, as assessed by clinical and radiographic parameters of bone destruction, were observed under a scanning electron microscope. Existence and location of root resorption areas, as well as length and depth of the resorption on each radicular third of the teeth, were determined.Totally 27 teeth (60%) among all the groups exhibited root resorption. The number of teeth showing root resorption in each group was divided into the following groups; Group I: 2 teeth (13.33%); Group II: 11 teeth (73.33%); and Group III: 14 teeth (93.33%). The most affected teeth were the mandibular incisors. The apical one-third of the root was the most affected and the gingival third of the root was the least affected with respect to the length and depth of the root resorption. The mesial surface of the root was more commonly affected when compared to the distal surface of the root.It may thus be concluded that the existence and extent of root resorption depend on the severity of periodontal destruction.
