Summary: | Background: Cigarette smoking is a public health issue that may influence the physical properties of dental composites. Surface
roughness is one of the physical properties of restorative materials potentially influencing their success. The use of nanofilled and
nanohybrid composites in dentistry has increased substantially over the past few years. Purpose: The purpose of this study was to
evaluate the surface roughness of nanofilled and nanohybrid composite resins exposed to kretek cigarette smoke. Methods: Twelve
cylindrical specimens of each material were prepared and divided into two groups (n=6). In the control groups, the specimens were
immersed in distilled water for 24 hours at 37°C, with the water being renewed daily. For the experimental groups, the specimens were
exposed to kretek cigarette smoke on a daily basis, then washed and soaked in distilled water at 37°C. After 21 days, the specimens
were measured using a Surface Roughness Tester and the data was then statistically analyzed. Results: An Independent-T Test
revealed that there were statistically significant differences in the surface roughness between the control and experimental groups of
both nanofilled and nanohybrid composites, as well as between the nanofilled experimental group and the nanohybrid experimental
group. Conclusion: Exposure to kretek cigarette smoke can increase the surface roughness of nanohybrid composites to a significantly
greater extent than nanofilled composites. |
