Pengaruh Konsentrasi Cangkang Kerang Darah (Anadara granosa) 25% Dan 50% Sebagai Bahan Pasta Polishing Restorasi Resin Komposit Nanohybrid Terhadap Kekasaran Permukaan (In Vitro)

Abstract

One of the key factors in the successful finishing and polishing process for restorations depends on the surface roughness of the material used. Commercial polishing pastes contain synthetic materials that are not biodegradable and can cause toxicity and irritation to the eyes and skin in some sensitive patients. Therefore, polishing pastes made from natural materials, namely blood clam shells, have been developed as an alternative base material for polishing pastes due to their abrasive properties. However, the optimal concentration of blood clam shells for polishing pastes is currently unknown. The purpose of this study was to determine the effect of blood clam shell (Anadara granosa) concentration as a base material for polishing pastes on the surface roughness of nanohybrid composite resin restorations. This laboratory experimental study used a post-test only group design. 32 maxillary premolar teeth underwent class V preparation procedures and were then restored using nanohybrid composite resin and divided into four groups, namely group I using blood clam shell polishing paste with a concentration of 25%, group II using blood clam shell polishing paste with a concentration of 50%, group III using commercial polishing paste and group IV without polishing paste. The samples were soaked in artificial saliva and placed in an incubator for 24 hours. The samples were subjected to surface roughness measurements using a profilometer. Statistical analysis was performed using ANOVA and Post Hoc Test LSD (Least Significant Difference) with a significance level of α = 0.05. The results of the One Way ANOVA test obtained a significant value of p = 0.000 (p <0.05) where statistically there was an effect of differences in particle size of blood clam shellbased polishing paste on the surface roughness of nanohybrid composite resin. A post-hoc LSD test was then conducted, and the results were There were significant differences between groups I, II, III, and IV. Surfaces polished using blood clam shells showed the lowest surface roughness compared to commercial pastes. The conclusion is that blood clam shell polishing paste with a concentration of 25% resulted in improved surface roughness.
