Prevalence of dehiscences and fenestrations in human cadavers

Abstract

Objective: the aim of the present study was to evaluate the prevalence of dehiscences and fenestrations in a convenience sample of human cadavers to provide accurate identification of bone defects. Material and Methods: twenty human cadavers, ranging in age from 20 to 40 years, were evaluated for dehiscences and fenestrations, which were verified after mucoperiosteal flap elevation. Results: the prevalence of dehiscences and fenestrations in the specimens was confirmed as being 40%, accounting for 5% of teeth with lesions. The most prevalent lesions were dehiscences, while only one single case of maxillary fenestration was observed. Conclusion: the planning of any periodontal plastic surgeries performed in the anterior region must take into account the possibility of periodontal defects. Therefore, considering the high prevalence of bone defects with potential impact in the esthetic outcome, the manipulation of soft tissues should be done carefully, especially in patients with a thin periodontium.any periodontal plastic surgeries performed in the anterior region must take into account the possible presence of periodontal defects.
