title: Cementum proteins: role in cementogenesis, biomineralization, periodontium formation and regeneration.
abstract: Destruction of the periodontium is normally associated with periodontal disease, although many other factors, such as trauma, aging, infections, orthodontic tooth movement and systemic and genetic diseases, can contribute to this process. Strategies (such as guided tissue regeneration) have been developed to guide and control regeneration using bioresorbable membranes and bone grafts. Although effective to a certain point, these strategies have the problem that they are not predictable and do not completely restore the architecture of the original periodontium. To achieve complete repair and regeneration it is necessary to recapitulate the developmental process with complete formation of cementum, bone and periodontal ligament fibers. Detailed knowledge of the biology of cementum is key for understanding how the periodontium functions, identifying pathological issues and for developing successful therapies for repair and regeneration of damaged periodontal tissue. It is the purpose of this review to focus on the role of cementum and its specific components in the formation, repair and regeneration of the periodontium. As cementum is a matrix rich in growth factors that could influence the activities of various periodontal cell types, this review will examine the characteristics of cementum, its composition and the role of cementum components, especially the cementum protein-1, during the process of cementogenesis, and their potential usefulness for regeneration of the periodontal structures in a predictable therapeutic manner.
