In vitro study of the film thickness of six resin cements

Abstract

Objectives. Study the differences of the film thickness of six cements to determine that they comply with the standards. Methodology. Experimental, cross-sectional, in vitro study. Film thickness test of resinous cements using the standards of ISO 9917-1. 30 samples were made dividing them into 6 groups of 5 samples each. Group 1: Prime Dent, Group 2, iCem, Group 3: Relyx Ultimate, Group 4: MaxCem, Group 5: TheraCem, Group 6: BisCem. The thickness of two glass slab placed one on top of the other was measured, the resin cement was prepared by placing it (0.05 ± 0.005 ml) at the center of the glass slab with a 3 ml syringe, it was measured again. The weight was removed after 10 minutes, the thickness of both glass slad was measured. Film thickness was calculated by taking the difference between the thickness of the glass slab with and without the sample between them. Results: An ANOVA test was performed to obtain the statistical value; it was obtained that p=0.000, therefore there are statistically significant differences between the cements. Contribution. The application of dental cements for indirect restorations is used daily, so knowing the film thickness provides security when choosing the ideal material.
