RESUMO
Cemento-osseous dysplasia (COD) is a non-neoplastic, usually asymptomatic condition characterized by the presence of amorphous cement-like calcifications located exclusively in the tooth-bearing regions of the jawbone. Simple bone cysts (SBCs) of the jaws are benign intraosseous cavities, empty or filled with serous, serohematic, or blood fluid. They are characterized by the absence of an epithelial lining. COD and SBCs are two distinct lesions of the jaws that have long been described separately in the literature; however, their co-occurrence remains rare and only a few cases have been reported illustrating this relationship. This association can be considered as a distinct entity since it presents specific epidemiological, clinical, and radiological data. The aim of this article was to report a new case of association between COD and SBC by illustrating a florid COD formation in mandibular SBC detected in a 31-year-old patient followed over a period of 11 years.
