UNLABELLED Tooth fractures (crown or root fractures) are commonly encountered emergencies in a dental clinic. Root fractures are defined as fractures involving the dentine, cementum and pulp. They are broadly classified as horizontal and vertical root fractures. They may be clinically challenging cases to treat as, usually, treatment of such cases requires an interdisciplinary/multidisciplinary...

Teeth develop as ectodermal appendages from epithelial and mesenchymal tissues. Tooth organogenesis is regulated by an intricate network of cell-cell signaling during all steps of development. The dental hard tissues, dentin, enamel, and cementum, are formed by unique cell types whose differentiation is intimately linked with morphogenesis. During evolution the capacity for tooth replacement ha...

Forensic odontology is the subdiscipline of dentistry which analyses dental evidence in the interest of justice. Oral pathology is the subdiscipline of dentistry that deals with the pathology affecting the oral and maxillofacial regions. This subdiscipline is utilized for identification through oral and maxillofacial pathologies with associated syndromes, enamel rod patterns, sex determination ...

The continuously increasing progress in stem cell biology has expanded our horizons into the principles of health and disease. This new acquired knowledge and the recent advances in the field of biotechnology have formed the substrate for translation into novel therapeutic solutions (Mitsiadis et al., 2015). Indeed, traditional dental therapies have successfully incorporated a good number of ne...

Hypercementosis is an abnormal thickening of cementum which may be generalized or localized. Localized hypercementosis is usually characterized by nodular enlargement of apical third of root. Hypercementosis in the form of multiple cemental spikes distributed throughout the entire length of root is a very rare finding. In this article, we report such a rare manifestation of localized hypercemen...

The discipline of Periodontology deals with the development, anatomy, structure, and function of the various soft and hard tissues of the periodontium in health and disease, i.e., gingiva, periodontal ligament, root cementum, and alveolar bone proper. It concerns diagnosis, prevention, and treatment of the various diseases and conditions affecting the periodontal tissues. There are close relati...

Identification of a person is the first basis for any forensic or medico-legal process. It is an important basis for differentiating guilty from innocent in legal issues, for ethical issues and for declaration of death reports and the basis for probing into criminal cases, mass disaster or war victims. The accurate estimation of age at the time of death with the help of dental remains is an imp...

This report contains a statistical review of 559 cases of lesions forming hard tissues that were diagnosed by the departments of Clinical Pathophysiology and of Pathology at Tokyo Dental College from 1966 to 2001. Sixteen kinds of lesions which were related to the formation of bone, cartilage or cementum were analysed: osteoma, osteo-chondroma, chondroma, osteoid osteoma, osteoblastoma, ossifyi...

Peripheral odontoma is rare, and only two cases of congenital peripheral odontoma have been reported. Congenital oral fibroma is also rare. We describe a unique case of congenital peripheral developing odontoma accompanied by congenital teratomatous fibroma in an infant. Both tumors were difficult to detect on radiography. Two small masses were seen in the median anterior portion of the palatal...

Tooth eruption is an orientating action which migrates teeth coronally during life, even in bone or after occlusion contact is lost. The eruption pathway is due to bone resorption near the enamel crown and bone deposition around the cementum-covered roots. Due to their proximity to bone resorption and deposition, we hypothesize that the hard tissues enamel, dentine or cementum are important dur...
