## Abstract The main objective of this study was to measure the fracture toughness of the human teeth enamel using the microindentation technique and to compare the results calculated from the equations developed for Palmqvist and radialβmedian cracks. Vickers microhardness measurements of dental c
A formula using the indentation fracture technique is given to determine the fracture toughness of ceramic materials. Experimental data are in good agreement with those obtained by the four-point bending technique. The factors that influence K,, are further discussed
