[Changes in the microhardness of the enamel and dentin in pulp inflammation]
Abstract:
Clinical and experimental studies of the dental enamel and dentin microhardness were carried out. A comparative analysis has made it possible to detect parallels in the changes of dental tissue microhardness in humans and dogs. The studies have revealed a focal pattern of demineralization, with the foci located mainly in the neck of the tooth and the pericervical portion of the root, indicating a considerable reduction of the functional resistance of pulpless teeth.
