Cementum is a hard, calcified tissue that covers the root of a tooth. It is a specialized type of connective tissue that is found in the periodontium, the tissues that surround and support the teeth. Cementum helps to attach the tooth to the periodontal ligament, which connects the tooth to the jawbone. This connection helps to keep the tooth firmly in place and allows the tooth to withstand the forces of chewing.
Cementum is made up of cells called cementoblasts, which are derived from mesenchymal cells in the connective tissue of the dental follicle. These cells produce the cementum matrix, which is composed of collagen fibers and other proteins. The cementum matrix is then mineralized, making the cementum hard and durable.
Cementum plays an important role in the health and function of teeth. It helps to protect the root of the tooth from damage and wear, and it helps to anchor the tooth to the jawbone. Without cementum, teeth would be much more susceptible to damage and loss.
Here are some key points about cementum:
- Location: Covers the root of a tooth.
- Function: Attaches the tooth to the periodontal ligament, helps with anchoring and supporting the tooth.
- Composition: Specialized calcified connective tissue, made up of cementoblasts and a matrix of collagen fibers and proteins.
- Role: Protects the root from damage, helps in tooth anchoring, and aids in tooth support.
Cementum is an essential part of the tooth structure, playing a vital role in tooth health and function.
