Abstract
often used nowadays because of the combination of filler
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
which has acidic pH. This study aimed to compare the effect of acid type of cuko pempek
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
Surface hardness was measured before and after immersion using Vickers Hardness Tester. Results
showed a significant difference on the surface hardness of composite resin before and after
ardness of microhybrid and nanohybrid composites after
(p<0,0167) showed statistically significant differences, while there were no
cuko pempek using vinegar and tamarind (p>0,0167). This study also
that there were significant differences on the surface hardness of microhybrid and nanohybrid composite after
cuko pempek using vinegar, and cuko pempek using tamarind (p<0,05).
face hardness of nanohybrid composite was lower than microhybrid composite after
using vinegar and tamarind.
