Root cementum


Cement is a thin layer of solid, mineralized connective tissue that covers the surface of the tooth root (Fig. 1-14).
  • Cement is applied and is attached to the root dentine. It has a light yellow color and softer or enamel, dentin.
  • Cement is bonelike tissue, which is more resistant to resorption of the bone [6].
Resistance to resorption (loss substances) is an important characteristic of cement, which makes it possible for teeth had been moved during orthodontic treatment [7]. High resistance of cement for resorption allows pressure during orthodontics to cause bone resorption of the alveolar ridge, to move the teeth, without a result of root resorption.
  • Cement is formed slowly throughout life. There are two main types of cement: cell and practice.
  • Cement does not have its own blood or nutrients; receives nutrients from the periodontal ligament.
Cement performs several important functions in the periodontium, and therefore the preservation of cement should be the goal of periodontal instruments.
  • The main function of the cement to give attachment to the collagen fibers of the periodontal ligament. Cement anchor the ends of the fibers of the connective tissues of parodentium teeth; without cement, the teeth would fall out of the nest.
  • The outer layer of cement protects the underlying dentin and seal the ends open dentinal tubules.
  • Cement education compensates for wear of the teeth for chewing or enamel surface due to attrition. Cement is formed on the apical region root to compensate occlusive depletion.
