Sometimes, it also has been seen that a portion of cementum has lost from the tooth and if, this portion is present in the transverse section then this also did not give the correct age estimation (Matson et al.

The activity of dental sac cells leads to the formation of the periodontal ligament and cementum [32].
The ultimate goal of periodontal regenerative therapy is to restore the supporting periodontal tissues (i.e., new periodontal ligament (NPL), new cementum (NC) interspersed with connective tissue fibers, and new alveolar bone) lost due to tooth injury or periodontal disease.
It is also known as a biocompatible material that may induce cementum formation around perforations and MTA.10 The most important reason to choose MTA as the permanent repair material in this case is because it has the capacity to promote hard tissue formation and to inhibit osteoclastic bone resorption.11 Here, at the patient's six-year follow-up, the resorbed tooth was asymptomatic, and radiographic examination confirmed that the large resorptive area filled with MTA was fully surrounded by new hard tissue (Figure-2D,E).

If left untreated, gingivitis will progress to periodontitis, a gradual destruction of the structures that hold teeth in position These structures are gingiva, bone, periodontal ligament and cementum, a bonelike substance covering the root of a tooth.
(3,5,9,21,22) Alterations of the tooth surface are directly related to the amount of pressure applied by an instrument--less pressure, less cementum removed.
"A normal tooth is made up of four tissues: Enamel, which is the strong white covering that protects the tooth; dentin, which supports the enamel and is a hard yellow material that carries nerves; pulp, which is at the center of the tooth and contains blood and lymph vessels; and cementum, which covers the root of the tooth," said Sabine.
