| Summary: | Background: Cigarette smoking is a public health problem that may influence physical properties of dental composites.
Surface roughness is one of the physical properties of restorative materials that can influence their success. The use of
nanofilled and nanohybrid composites in dentistry has substantially increased 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 were prepared of each material and divided into two
groups (n=6). For the control groups, the specimens were immersed in distilled water for 24 hours at 37oC and the
water was renewed daily. For the experimental groups, the specimens were exposed daily to kretek cigarette smoke,
then washed and stored in distilled water at 37oC. After 21 days, specimens were measured using a Surface Roughness
Tester and the data was statistically analyzed. Result: Independent-T Test revealed that there were statistically
significant differences in the surface roughness between control and experimental groups both nanofilled and
nanohybrid, and between experimental groups nanofilled and nanohybrid. Conclusion: The exposure to kretek
cigarette smoke can significantly increase the surface roughness of nanohybrid composites more than nanofilled
composites. |
