Pengaruh Formulasi Basis Pasta Polishing Restorasi Resin Komposit Nanohybrid dari 25% Cangkang Kerang Darah (Anadara Granosa) terhadap Kekasaran Permukaan (In Vitro)

Abstract

The success of the restoration is influenced by the polishing procedure at the final stage of the restoration, resulting in a smooth surface. A potential abrasive material for polishing paste is blood clam shells. The purpose of this study was to investigate the effect of a paste base formulation between CMC-Na and carbomer on polishing paste from blood clam shell powder on the surface roughness of nanohybrid composite resin restorations. The cleaned blood clam shells were pulverized using a ceramic mortar, sieved using a 400 mesh sieve, and pulverized again using a ball-mill machine. Samples of 24 maxillary premolars were treated with Class V and restored with nanohybrid composite resin. The samples were divided into 4 groups: polishing with blood clam shell paste CMC-Na paste base formulation, carbomer paste base, commercial paste, and no paste. Surface roughness testing was carried out using a profilometer. The results of the One Way ANOVA test showed that there was an effect of polishing paste formulation on the surface roughness of nanohybrid composite resin (p<0.05). Then the results of the LSD Post Hoc Test showed that there was a significant difference in influence between the paste group from blood clam shells and commercial pastes with carbomer paste base formulations showing lower surface roughness values than CMC-Na paste base formulations. In conclusion, the formulation of polishing paste base from blood clam shells formulated with carbomer and CMC-Na affects the surface roughness of the restoration.
