Abstract


The influence of different specimen thicknesses on the tensile strenght (by diametral compression method 11) of dental stones has been studdied. It was observed that there was greater reproducibility os results as the thickness of the samples decreased. This leads us to recommend the latter type os samples when conducting diametral compression tensile strenght tests. A relationship between the compression strenght and tensile strenght was also studdied. It was found that the difference between the two strenghts decrenses as the thickness os the diametral compression strenght samples increases. The results were expressed in stress values.
