Abstract

Background: Nanohybrid composite has filler with variation of size and contain nano-sized particles. The decreasing of surface hardness can be occured because consumption of acid pH beverages, carbondioxide (CO2) from soft drinks and water. Sugary soft drink (coca-cola) has lower pH than aspartame soft drink (coca-cola zero). Besides the difference of pH, aspartame soft drink (coca-cola zero) contains fenilalanin amino acid the product of hydrolisis reaction of aspartame so the acid environment become neutral. Purpose: To view the differences of nanohybrid resin composite after being soaked in sugary soft drink and aspartame soft drink. Methods: There are significant differences between samples being soaked in aquades and aspartame soft drink (coca-cola zero) and sugary soft drink (coca-cola). There are significant differences between aspartame soft drink (coca-cola zero) and sugary soft drink (coca-cola). Conclusion: Surface hardness of nanohybrid resin composite is lower after being soaked in sugary soft drink (coca-cola) than after being soaked in aspartame soft drink (coca-cola zero).

Abstract

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.
