“What are the Differences Between the Osteoma, Cementoblstoma, and Cemento-Ossifying Fibroma?”

7.16.24 Quick Review #180 - #pathology #oralpathology #doctorgallagher #oralsurgery #oralsurgeon #dentist #dentistry #dental Osteoma - benign tumors composed of mature, compact, or cancellous bone. Characteristics: • Growth: Slow-growing. • Location: Commonly found in the craniofacial region, especially the paranasal sinuses, mandible, and skull. • Radiographic Appearance: Radiopaque mass with a well-defined border; it can be sessile or pedunculated. • Symptoms: Often asymptomatic but can cause swelling or asymmetry if large. Histopathology: • Composed of dense, mature bone with little marrow spaces. Clinical Significance: • Generally, no malignant transformation. • May be associated with Gardner’s syndrome, which includes multiple osteomas, colorectal polyps, and soft tissue tumors. Cementoblastoma - benign tumors of cementum-producing cells (cementoblasts). Characteristics: • Growth: Slow-growing but can be aggressive. • Location: Most commonly associated with the roots of mandibular molars and premolars. • Radiographic Appearance: Well-defined radiopaque mass attached to the root of a tooth, often with a surrounding radiolucent halo. • Symptoms: Pain and swelling are common due to the tumor’s pressure on the surrounding bone and nerves. Histopathology: • Consists of sheets of cementum-like material with entrapped cementoblasts and cementocytes. Clinical Significance: • Can cause root resorption. • Treatment often involves surgical removal of the tumor and associated tooth. Cemento-Ossifying Fibroma (COF) - a benign fibro-osseous lesion composed of fibrous tissue, bone, and cementum-like material. Characteristics: • Growth: Slow-growing but can cause significant expansion. • Location: Commonly affects the mandible, especially the premolar and molar regions. • Radiographic Appearance: Mixed radiolucent-radiopaque lesion with a well-defined border; early stages may appear more radiolucent, becoming more radiopaque as it matures. • Symptoms: May cause facial asymmetry, swelling, and displacement of teeth. Histopathology: • Composed of fibrous connective tissue with varying amounts of calcified bone and cementum-like material. Clinical Significance: • Treated with surgical excision. • Recurrence is uncommon but can occur if not completely removed. References: 1. Dr. G’s Toothpix. (n.d.). Cementoblastoma.
