dc.description.abstractThe effects of surface finish on flexural strength and surface roughness of a feldspathic porcelain (Vita Omega), aluminous porcelain (Vita AIpha) and a computer aided design-computer aided manufacture porcelain (Vita MKII) were examined. Testing bars were fabricated by conventional technique for Vita Alpha &Vita Omega groups. MKII specimens were obtained by sectioning from a manufacturer's prefabricated block. Vita Alpha & MKII had 5 surface treatment groups and Vita Omega had an additional 4 groups. The groups consisted of self-glaze, Shofu polish, overglaze, Perladia polish, and Buehler polish. The additional groups consist of Buehler combined with Shofu and Perladia; overglaze combined with Shofu and Perladia. All groups were subjected for surface roughness evaluation with the aid of S.E.M. and profilometric analysis. Overglaze significantly increased (p[less than].05) flexural strength (three-point-bending) and had the smoothest surface of all three ceramic materials. Self-glaze, Shofu, Perladia and Buehler had no statistical difference in flexural strength among Vita Alpha and Vita Omega groups.en_US
