Abstract
The purpose of this study was to determine and compare the film thickness of four resin cements, named Enforce (Caulk/Dentsply), Nexus (Kerr), Rely X (3M of Brazil) and Panavia 21 (Kuraray). The method was in compliance with American Dental Association Specification no 8 for zinc phosphate cement. Statistical analysis was carried out using the Kruskal-Wallis test (α = 0.01). The mean film thickness values (μm) of the four cements were: Enforce = 27.7; Nexus = 34.9; Rely X = 25.5 and Panavia 21 = 21.9. There was no statistical significant difference between the film thickness of Enforce and Rely X. The cements Panavia 21 and Rely X also demonstrated no statistical significant difference. Panavia 21 demonstrated the lowest and Nexus the highest film thickness values.

Resumo
O propósito deste estudo foi determinar e comparar a espessura de película de quatro cimentos resinosos, denominados Enforce (Caulk/Dentsply), Nexus (Kerr), Rely X (3M do Brasil) e Panavia 21 (Kuraray). O método utilizado foi baseado na Especificação no 8 da American Dental Association para cimento fosfato de zinco. A análise estatística foi realizada utilizando-se o teste de Kruskal-Wallis (α = 0,01). Os valores médios (em micrômetros) obtidos para a espessura de película dos quatro cimentos foram: Enforce = 27,7; Nexus = 34,9; Rely X = 25,5 e Panavia 21 = 21,9. Não houve diferença estatística entre os valores encontrados para Enforce e Rely X e entre Panavia 21 e Rely X. Panavia 21 demonstrou o menor e Nexus, o maior valor de espessura de película.
