Summary:Made available in DSpace on 2014-11-10T11:10:01Z (GMT). No. of bitstreams: 0 Previous issue date: 2000-06-30Bitstream added on 2014-11-10T11:57:20Z : No. of bitstreams: 1 000124943.pdf: 2856695 bytes, checksum: d61150204b12b1d758131e6fb0dbf8e1 (MD5) === O propósito deste estudo foi avaliar a rugosidade superficial entre materiais de revestimento estético indiretos (Vita VMK95, Solidex, Artglass, Targis). Para tanto, confeccionaram-se 10 corpos-de-prova nas dimensões de 6mm de comprimento por 6mm de diâmetro de cada material. Uma das superfícies planas recebeu acabamento e polimento, conforme recomendações do fabricante. As amostras concluídas foram submetidas a mensuração, através do rugosímetro Hommel Tester T500. Os valores médios de rugosidade máxima entre os materiais em questão, foram 5,731Jm, 5,151Jm, 6,83 1.1m e 3, 721Jm, respectivamente. A seguir foram submetidos a análise de variância (ANOVA), ao nível de 5%, sendo detectado significância. Concluiu-se que o material Sofidex não apresentou diferença estatisticamente significante entre os grupos, enquanto o Targis apresenta significância estatística em relação ao Artglass e a cerâmica Vita vmk95. === The purpose of this study was to evaluate surface rugosity among indirect esthetic materials (Vita VMK 95, Solidex, Artglass, Targis). Ten samples of each material in the cilindric shape with dimension 6 x 6 mm were manufactured. The surface were submitted to finishing and polishing, according to manufacturer's recommendations. The samples were submitted to measuremenst, using the Hommel Tester T500 device. The average values of maxim surface rugosity among the materiais ín question, were 5, 73pm; 5, 15pm; 6, 83 j.Jm e 3, 72 j.Jm, respectively. Sample were also subjectted to variance analysis- ANOVA (5%), had detected significance. Concluded that the material Solidex did not present significant statistical differences among groups, while Targis presented significant statistical differences in relation to the Artglass and the ceramic Vita vmk95.
