Abstract  Hypercementosis is identified by an excessive, non-neoplastic deposition of radicular cementum and is mostly presented as a solitary lesion or in rare cases as a multiple type.

Hypercementosis presents as painless, single or multiple non-neoplastic cementum formation beyond the physiological limits of the tooth. It often occurs in the apical area of the involved tooth following infection, chemical or mechanical trauma. We report on radiographic and histopathological findings in a single case of late intraosseous hypercementosis and odontogenic epithelial hyperplasia a...

PURPOSE Periodontal regenerative therapies for defects created by severe periodontitis are mainly focused on bone regeneration. Although cementum regeneration needs to be better understood, it is believed to play an important role in periodontal regeneration. The first step toward a full understanding of cementum regeneration is to compare repaired cementum to pristine cementum. This study, whi...

The extracellular matrix (ECM) of cementum resembles other mineralized tissues in composition; however, its physiology is unique, and it contains molecules that have not been detected in other tissues. Cementum components influence the activities of periodontal cells, and they manifest selectivity toward some periodontal cell types over others. In light of emerging evidence that the ECM determi...

Dental cementum is a vital tissue which demonstrates continuous apposition throughout the life of the tooth. This study was conduct on 101 impacted and 106 erupted mandibular third molar teeth extracted from healthy patients, aged 18-30 years. The buccolingual ground sections were prepared. The distance between the edges of enamel and cementum were measured with micrometer attached with light m...

According to the findings of various authors, almost 100% world's population suffers from dental caries. Carious lesions cervical area teeth attract special attention since their localization does not provide for early detection pathological process, and features microbiocenosis oral cavity structural enamel-cementum-dentine junction are significant risk factors development progression The aim ...

BACKGROUND AND OBJECTIVE Cementum is a mineralized tissue that facilitates the attachment of periodontal ligament to the root and surrounding alveolar bone and plays a key role in the regeneration of periodontal tissues. The molecular mechanisms that regulate the proliferation and differentiation of cementoblasts, however, have not been elucidated to date. Enamel molecules are believed to regul...

This work seeks to establish comparisons of the physical properties of rat and human cementum, root dentin and their interface, including the cementum-dentin junction (CDJ), as a basis for future studies of the entire periodontal complex using rats as animal models. In this study the structure, site-specific chemical composition and mechanical properties of cementum and its interface with root ...
