Abstract

Introduction: Hybrid composite is often used nowadays because of the combination of filler size results in restorations with good aesthetic and mechanical strength. Various factors in the oral cavity such as acid solution can affect the surface hardness of composite resin. Cuko pempek is an additional sauce that served for pempek which has acidic pH. This study aimed to compare the effect of acid type of cuko pempek on surface hardness of microhybrid and nanohybrid composite. Materials and Methods:Thirty-six samples of microhybrid (n=18) and nanohybrid composite (n=18) with 5 mm in diameter and 2 mm in thickness were immersed in three different solutions: artificial saliva (control), cuko pempek using vinegar, and cuko pempek using tamarind. Surface hardness was measured before and after immersion using Vickers Hardness Tester. Results:The result of this study showed a significant difference on the surface hardness of composite resin before and after immersion (p<0,05). The surface hardness of microhybrid and nanohybrid composites after immersed in artificial saliva and cuko pempek (p<0,0167) showed statistically significant differences, while there were no significant differences between cuko pempek using vinegar and tamarind (p>0,0167). This study also showed that there were significant differences on the surface hardness of microhybrid and nanohybrid composite after immersion in artificial saliva, cuko pempek using vinegar, and cuko pempek using tamarind (p<0,05). Conclusion:The surface hardness of nanohybrid composite was lower than microhybrid composite after immersed in cuko pempek using vinegar and tamarind.
