Abstract
The aim of this study was to evaluate the surface roughness of Noritake® ceramic after different methods of finishing and polishing. 40 specimens of Noritake® ceramic were randomly divided into 4 groups (n=10) and subjected to different methods of finishing and polishing: Group 1 (control) - glaze; Group 2 - abrasive rubbers Astropol (Ivoclar Vivadent), felt disc and diamond paste; Group 3 - abrasive rubbers (Edenta), felt disc and diamond paste; Group 4 - Sof-Lex discs (3M ESPE), felt disc and diamond paste. Subsequently, the surface roughness was measured with rugosimeter (Mitutoyo SJ 301). The control group (G1) had the lowest surface roughness (0.68 μm) that was different statistically to the other groups (p0.05). The different methods of finishing and polishing were not able to promote a surface as smooth as the application of glaze in the ceramics tested.

Desde sua introdução na odontologia, as cerâmicas têm merecido atenção e destaque, e a principal razão para isso é que, até então, nenhum outro material consegue reproduzir a beleza e a naturalidade dos dentes
Summary
Mario Cezar Oliveira*, Alex Correia Vieira*, Adriana Castro Andrade*, Indira Almeida Oliveira**. O objetivo desse estudo foi avaliar a rugosidade superficial da cerâmica Noritake® após diferentes métodos de acabamento e polimento. Foram confeccionados 40 corpos de prova da cerâmica Noritake®, divididos aleatoriamente em 4 grupos (n=10) e submetidos a diferentes métodos de acabamento e polimento: Grupo 1 (controle) – aplicação do glaze; Grupo 2 – borrachas abrasivas Astropol (Ivoclar Vivadent), disco de feltro e pasta diamantada; Grupo 3 – borrachas abrasivas (Edenta), disco de feltro e pasta diamantada; Grupo 4 – discos Sof-Lex (3M-ESPE), disco de feltro e pasta diamantada. Após a realização destes procedimentos, todos os corpos de prova foram submetidos a análise quantitativa da rugosidade superficial em rugosímetro Mitutoyo SJ 301. Os diferentes métodos de acabamento e polimento não foram capazes de promover uma superfície tão lisa quanto à aplicação do glaze na cerâmica testada.
