First, the compressive strength of each cement was tested according to a standard (ISO 9917-1:2004). The time had correspondingly effectively increased impact on the dental materials used in this study. Mechanical properties of importance to dentistry include brittleness, compressive strength, ductility, elastic modulus, fatigue limit, flexural modulus, flexural strength, fracture toughness, hardness, impact strength, malleability, percent elongation, Poisson’s ratio, proportional limit, shear modulus, shear strength, tensile strength, torsional strength, yield strength, and Young’s modulus. 500 500 500 500 500 500 500 549 500 500 500 500 500 444 500 444 Estadual Paulista-UNESP Araraquara, SP, Brazil Compressive Strength The compressive strength of CC&B luting cement was measured according to ISO 9917:1(2003), Annex D, with a minor modification (ISO 9917-1, 2003).4 (The modification was that the CC&B test material, while still in the stainless-steel mold during setting, was maintained in 100% humidity during early setting [a step not listed in the ISO test method] due to the fact that it is a hydraulic cement and sets optimally in a somewhat moist or high humidity environment during initial setting.) 360 562 300 300 300 519 500 300 300 300 319 469 750 750 750 356 317 319 500 500 556 500 234 500 300 663 500 469 525 300 663 497 Evaluation of compressive strength and void content of resin based dental composites. 400 549 300 300 333 576 453 333 333 300 319 500 750 750 750 356 Cylindrical samples with diameter to height ratio 1 to 2, were prepared via molding method. 388 469 238 217 451 217 645 217 649 343 649 649 577 577 577 343 J Prosthet Dent, (5):481-485 MED: 7844747 All samples were matured for 1 day, 1 week, 1 month or 3 months before compression, and edge tests were performed respectively on the whole surface (compressive strength, CS) or on the edge (edge stability, ES) using a universal testing machine. ] In other words, compressive strength resists being pushed together, whereas … ] The highest average compressive-strength value of 40,200 psi reported for cusp enamel is, in gen-eral, lower than those reported for dentin.'
