The role of piezosurgery in the treatment of a rare case of superinfected cemento-osseous dysplasia caused by actinomyces: A case report

Abstract

Cemento-osseous dysplasia is a benign fibroosseous lesion affecting the alveolar bone. It is classified into three forms: periapical, focal or florid dysplasia. It is often asymptomatic and fortuitously discovered during a routine radiological examination. However, it may become symptomatic after superinfection, after patient's exposure to oral bacterial flora. We here report a case of florid cemento-osseous dysplasia associated with actinomycosis of bone in a 53-year-old Tunisian woman. This superinfection has been rarely reported in the literature; Boolean Searching on PubMed for the keywords "cemento-osseous dysplasia AND actinomyces" displays a single article (Smith et al. 2011). The treatment of actinomycosis infection often requires long-term antibiotic therapy, sometimes associated with surgical debridement, as in the case of this patient who underwent piezosurgery to treat dysplasia and necrotic bone.
