| Research Abstract |
The fracture toughness was shown to be dependent upon the structural qualities of enamel specimens. The fracture toughness value (K_<IC>) in the indentation area from 40 to 70% toward the cusp was a significant larger than the area from 70 to 100%. The clear clack configuration was restrictive accepted as data of results in the indentation area from 0 to 40% because there was small number of clear clack conf igurat ion. It was recognized that the Vickers microhardness numbers do not depend upon the the magnitude of the applied load. The results of quantitative analysis us ing peripheral quantitative computed tomography also were supported for the obtained mechanical f indings
