“What are the 3 Types of Cemento-Osseous Dysplasia?”

6.6.24 Quick Review #143 - #pathology #oralpathology #doctorgallagher #oralsurgery #oralsurgeon #dentist #dentistry #dental Cemento-Osseous Dysplasia (COD) is a benign fibro-osseous lesion of the jaw that can be classified into three main types: periapical, focal, and florid. Here are the different types and their characteristics: 1. Periapical Cemento-Osseous Dysplasia (PCOD) - Location: Typically affects the anterior mandible. - Demographics: More common in middle-aged African-American women. - Radiographic Features: Initially presents as radiolucent lesions around the apices of the teeth, which become mixed radiolucent-radiopaque, and finally turn completely radiopaque as they mature. - Symptoms: Usually asymptomatic and detected incidentally on radiographs. 2. Focal Cemento-Osseous Dysplasia (FCOD) - Location: Occurs in a single site, usually in the posterior mandible. - Demographics: Can affect any demographic but more common in middle-aged women. - Radiographic Features: Similar progression from radiolucent to mixed radiolucent-radiopaque, to radiopaque. The lesion is typically well-circumscribed. - Symptoms: Typically asymptomatic and found incidentally during radiographic examination. 3. Florid Cemento-Osseous Dysplasia (FLCOD) - Location: Involves multiple quadrants of the jaw, affecting both the maxilla and mandible. - Demographics: Predominantly seen in middle-aged African-American women. - Radiographic Features: Multiple mixed radiolucent-radiopaque lesions in different quadrants. As the lesions mature, they become predominantly radiopaque with radiolucent borders. - Symptoms: Generally asymptomatic but can become symptomatic if secondary infection occurs or if there is exposure to the oral cavity due to sequestration. Characteristics and Differences: - Location: PCOD is confined to the anterior mandible, FCOD is typically a single site in the posterior mandible, and FLCOD involves multiple jaw quadrants. - Radiographic Appearance: All types show a progression from radiolucent to radiopaque lesions, but their distribution varies (localized in PCOD and FCOD, widespread in FLCOD). - Symptoms: Usually asymptomatic, though FLCOD has a higher risk of complications if secondary infections occur. - Demographics: PCOD and FLCOD are more common in African-American women, while FCOD does not show a strong demographic predilection.
