Cementum

Cementum is a specialized, calcified connective tissue that covers the anatomical roots of a tooth. It is formed by cementoblasts and primarily composed of hydroxyapatite, similar to bone. Cementum's main function is to provide a medium for the attachment of periodontal ligament fibers, securing the tooth to the alveolar bone within the socket. The thickness of cementum varies across the root surface, becoming thickest at the apex. It is a dynamic tissue capable of repair and remodeling throughout life. It is responsible for the support, anchoring and repair of the tooth within the bony socket.

Cementum meaning with examples

• The orthodontist examined the patient's X-rays, noting the health of the cementum and its role in the stability of the teeth. The integrity of the cementum is crucial for successful orthodontic treatment. A weak cementum can impede tooth movement.
• During a periodontal examination, the dentist assessed the cementum for any signs of inflammation or damage. The cementum helps keep the tooth rooted. Healthy cementum is essential for maintaining a strong and healthy foundation for the teeth, which is important for long-term oral health.
• Cementum deposition occurs constantly to adapt to tooth wear and maintain its attachment. The process involves the creation of new layers to ensure efficient function of the teeth. cementum is vital for the attachment of fibers.
• The process of tooth extraction involves separating the tooth from the cementum and surrounding tissues. This may also include carefully separating the cementum from other parts of the tooth and surrounding tissue. The cementum’s strength holds the tooth.
