Abstract
RATIONALE: The term cemento-osseous dysplasia (COD) refers to a bony fibro-osseous lesion, in which fibrous tissue and cementum-like tissue replace normal bone. There are three types of COD: periapical, focal and florid. The condition is usually asymptomatic and treatment is unnecessary; however, a secondary infection could occur, which requires treatment. PATIENT CONCERN: A 58-year-old female patient presented with symptoms in the mandibular posterior region of the right jaw for six months. DIAGNOSIS: Infected florid COD (FCOD). TREATMENT: A pre-operative antibiotic, followed by extraction of non-restorable teeth, debridement of the infected tissue and necrotic bone removal. OUTCOME: The patient was followed for one year, during which all previously reported signs and symptoms were resolved. TAKE-AWAY LESSONS: Early lesion detection is essential. Treatment depends on the presence or absence of clinical and radiographic manifestations. The current case was treated surgically to minimise complications.
