LOBO, Gessana Maria et al. Gingival alterations in areas adjacent to overhanging Class II restorations. Odontol. Clín.-Cient. (Online) [online]. 2011, vol.10, n.4, pp. 357-359. ISSN 1677-3888.

Introduction: The proximal restorations still represent a challenge in the practice of restorative dentistry. Overhanging restorations are frequently observed, favoring the accumulation of plaque in the region and may interfere in the maintenance of healthy gums. Objective:The aim of this study was to detect the prevalence of overhanging class II restorations and the relationship with gingival alterations in two Dental Clinics at the School of Dentistry of Federal University of Maranhão. Materials and Methods: Twenty patients were assessed by clinical and radiographic examination in order to observe overhanging restorations, probing pocket depth and gingival bleeding in the areas adjacent to the proximal restorations. Results: There were found 55 proximal surfaces restored with amalgam or composite resin which showed a relatively high number of overhanging surfaces (50,9%), increased probing pocket depth and presence of gingival bleeding in the adjacent areas to the restorations. Conclusions: Authors had concluded that overhanging restorative material represents damage to gingival tissues, being directly related to increased periodontal pocket depth and gingival bleeding.
