RESUMO
This study evaluated the effect of antiasthmatic medication on the surface roughness and color stability of dental restorative materials. A total of 60 disc-shaped specimens were fabricated from glass ionomer [n = 20], composite resin [n = 20] and feldspathic porcelain [n = 20]. Each material group was randomly divided into two subgroups [n = 10]: [1] control group and [2] test group. Control groups of the specimens were kept in artificial saliva. Test groups were exposed to salbutamol sulfate [Ventolin Nebules] using an inhaler machine. Surface roughness measurements were done using a profilometry and color measurements were done with digital colorimetry at baseline and after inhalation and storing in artificial saliva. A two-way analysis of variance [ANOVA] and post-hoc Fisher's least significant difference test were used to compare the change in surface roughness and color. The confidence level was set at 95%. Inhaler treatment significantly increased the surface roughness and color change of glass ionomer and composite resin materials [p < 0.05], while the surface roughness and color of feldspathic porcelain was not changed after inhaler treatment [p > 0.05]. The antiasthmatic inhaler medication [salbutamol sulfate] affected the surface roughness and color of composite resin and glass ionomer restorative materials
