Abstract

Purpose: This in vitro study aims to assess the impact of cigarette smoke and carbonated drinks on the surface roughness and color change of two single-shade composites.
Materials and Methods: 96 specimens of Omnichroma and Vittra APS Unique RBC discs were prepared on Teflon Mold. Each composite group was divided into four subgroups according to exposure material. Control where specimens were kept in distilled water, cigarette smoking, Immersion in cola, and mixed group. The surface roughness and color change values were recorded using a profilometer and CIE L* a* b*, respectively. The recorded data were statistically analyzed.
Results: Significant difference in the mean surface roughness values among both resin composites tested was shown in all subgroups except mixed Cola and Cigarette subgroup where Vittra APS Unique revealed higher surface roughness than Omnichroma. There was an insignificant difference among different subgroups with the highest mean value for the mixed subgroup in Omnichroma and Cigarette subgroup in Vittra resin composite. Regarding the results of the color stability, there was a significant difference in the mean ∆E among both tested resin composites with higher values for Vittra APS Unique. There was a significant difference among different subgroups with the highest mean value for Cola subgroup in both resin composites.
Conclusion: Cigarette smoking and Cola intake harm the surface roughness and color stability of Vittra APS Unique more than Omnichroma single-shade composite. Although combined use of cola and cigarette didn’t affect the surface roughness, it positively affected the color change values of both composites.
