[15] Kim et al attempted to regenerate alveolar bone, pulp, cementum, PDL and dentine of mandibular molars by a feasible method using cell homing, in animal model.
Rygh and co-workers have shown that cementum adjacent to hyalinized areas of the periodontal ligament is marked by this contact and that clast cells attack this marked cementum when the periodontal ligament area is repaired, especially in upper incisor region.5,6
Due to exposure to low frequency noise, the cementum in the alveolar bone disappears and the surface of the bone gets irregularly eroded with some evidence of bone necrosis.
Different methods starting from the tooth eruption (Andrews 1981), x-ray (Simon & Frydendall 1981), cementum layers count (Matson et al.
(1) These lesions are considered the only true neoplasm of a cementum origin (2) and are defined as neoplasms characterized by the formation of sheets of a cementum-like tissue containing a large number of reversal lines and a lack of mineralization at the periphery of the mass or in the more active growth area.
I sent the incisor teeth out to Wildlife Analytical Labs in Texas, where the cementum annuli method was used to confirm the buck's age at 5 1/2 years.
Filling material so should be biocompatible, non-toxic, non-carcinogenic, easily obtainable, convenient to use, inexpensive, and promote the growth of cementum or allow for its replacement by new, healthy bone by acting as a barrier against which the root canal obturating material can be placed.
In 2016, the LANAP protocol was awarded the world's first US FDA clearance for True Periodontal Regeneration--regenerating alveolar bone, periodontal ligaments and cementum on a diseased root surface.
The major risk of this technique is resorption and loss of the tooth because of the history of trauma, the high concentration of hydrogen peroxide used, the high heat used to activate the bleaching agent, the absence of seal over the gutta-percha and the absence of connection between enamel and cementum. 27 For this technique, it is recommended to isolate the tooth with a rubber-dam.
