Periodontal and Dental Considerations in Florid Cemento-Osseous Dysplasia: Clinical and Radiographic Analysis of 11 Cases

Purpose: Florid cemento-osseous dysplasia (COD) is a well-described condition that occurs predominantly in black women. The lesion is usually asymptomatic, but in severe cases, symptoms can occur in association with focal expansion due to infection. The safety of dental procedures that involve areas with florid COD has been little discussed. Therefore, the present study aims to emphasise the importance of nonsurgical periodontal treatment in patients with periodontal diseases and COD. Materials and Methods: Four thousand five hundred panoramic radiographs from the image bank of the School of Dentistry of Ribeirão Preto were clinically and radiographically evaluated. Results: Eleven patients had images compatible with florid COD. Eight patients were asymptomatic and three symptomatic. All patients were diagnosed with chronic periodontitis (CP) and their panoramic radiographs showed mixed radiopaque and radiolucent images in the alveolar bone. In symptomatic patients, besides the clinical signs of CP, exposed bone with severe suppuration occurred in the posterior region of the mandible. Conclusions: The maintenance of systemic and oral health is mandatory to prevent secondary infections, and knowledge about the interface between different dental specialties and florid COD management may prevent erroneous decisions and ensure patient safety, taking into account the dental treatment that can be performed without further complications.
