The effect of soaking blimbi (Averrhoa blimbi, L) fruit extract on the roughness of nanofiller composite resin

Background Nanofiller composite resin is a restorative material or filling material that is activated by visible light to restore anterior and posterior teeth. One of the characteristics of the composite resin surface is surface roughness. Surface roughness is greatly influenced by acidic solutions, namely the acid in drinks. Objective: To determine the effect of soaking blimbi fruit extract (Averrhoa blimbi L.) on the roughness of nanofiller composite resin. Research Method: This research uses laboratory experimental research. The sampling method used 6 sample groups in each group, consisting of 4 groups, namely 2 treatment groups and 2 control groups. The treatment group consisted of 50% and 100% blimbi fruit extract, then the control group consisted of a positive control grup (citric acid) and a negative control (aquadest). Then a surface roughness test was carried out on each group using a Surface Roughness Tester tool, then the test data was analyzed using the One-Way Anova test with the condition that the data had to be normal and homogeneous, the condition for the One-Way Anova test was that the sig value Sig <0.05. Results: Based on analysis using One-Way Anova, the sig 0.518 (p>0.05), which means there are no significant differences in each sample group. Conclusion: There is no influence on the roughness of the nanofiller composite resin by soaking in star fruit extract (Averrhoa blimbi, L) because the value difference is not significant.
