摘要
Objective To evaluate coating materials regarding color and roughness changes when applied over a composite resin. Materials and Methods Specimens were made using Filtek Supreme Ultra. Coating materials were applied over the specimens' surface: Control (CTRL); Adper Single Bond Plus (SB); Scotchbond Universal (US); Clearfil SE (CL); Ambar APS (APS); Bioforty (BF); Fortify (FF); PermaSeal (PS); G-CoatPlus (GC). Specimens were evaluated regarding color changes ( increment E-00) using spectrophotometer (n = 10); surface roughness (Ra), using optical profilometer (n = 10); surface topography, using scanning electron microscopy (n = 1); and thickness of material, using optical microscopy (n = 1). Analyses were made before and after 24, 72, and 168 hours of storage in wine, used as a staining solution. Data was statistically analyzed using analysis of variance, Tukey and Pearson tests (alpha:.05). Results None of the materials presented color stability. increment E-00 increased with increasing storage time at red wine, until 72 hours. BF, FF, PS, SB, and CTRL presented the lowest increment E-00 after 24 hours. APS presented the highest increment E-00 (32.59; P < .05). Regarding roughness, initially, surface sealants and APS presented the lowest values. After 168 hours, GC presented the lowest Ra (0.60; P < .05). Conclusions All the materials presented color and roughness changes after storage in red wine. Clinical Relevance Some coating materials can be applied over the surface of RBC restorations without changing its color stability or surface roughness.
