Using X-ray computed microtomography for investigation of the morphology and composition of the hard tooth tissue

Abstract

The study shows that the X-ray computed microtomography is a prospective method of revealing and studying early alterations of enamel and dentine. The offered complex approach allows obtaining complimentary detailed information on density distribution, morphological structure, and chemical composition of hard tooth tissues. It opens new opportunities for development of preventive measures and treatment of the main dental diseases. The morphology and composition of the human hard tooth tissue and dog odontoma were studied by optical microscopy, SEM, X-ray microtomography and EDX-analysis. Microstructure of hard tissues of teeth reflects complex processes associated with age and pathological changes (caries, non-carious lesions). Odontoma is one of the more often common benign tumors developing in the oral cavity and located in jaws bone. Possible causes of occurrence and development are not understood well.
