Cementum is formed by the organization of collagen fibrils which are cemented together by a matrix produced by the polymerization of mucopolysaccharides which becomes mature cementum upon calcification.
Abstract
The primary cementum is formed initially by appositional growth from the dental sac and later from the periodontal membrane under the influence of cementoblasts. It is formed in laminated layers with the incorporation of Sharpey's fibers into a fibrillar matrix which undergoes calcification. Cementum deposition is a Continuous process throughout life with new cementum being deposited over the old cemental surface. Cementum is formed by the organization of collagen fibrils which are cemented together by a matrix produced by the polymerization of mucopolysaccharides. This material is designated as cementoid and becomes mature cementum upon calcification. The significance of the continuous deposition of cementum has received various interpretations.
