Pengaruh Penggunaan Bur Rubber Cup dan Felt Cone Sebagai Rotary Instrument Pada Aplikasi Pasta Polishing Berbahan Dasar Cangkang Kerang Darah 25% Terhadap Kekasaran Permukaan Restorasi Resin Komposit Nanohybrid (In Vitro)

Abstract

The long-term success of composite restorations depends largely on their smoothness, which can be achieved with the right polishing tools and material selection. The surface roughness of composite resins is influenced by several intrinsic and extrinsic factors. Extrinsic factors relate to methods at the finishing and polishing stage, such as materials, tools, and polishing techniques. The use of polishing paste at the polishing stage can result in a smooth and shiny restoration surface. In addition, there are abrasive and non-abrasive rotary instruments as polishing paste applicators, namely bur rubber cup and bur felt cone. Currently, pasta made from blood clam (Anadara granosa) shells is being developed. The purpose of this study was to determine the difference in the effect of blood clam shell paste (Anadara granosa) and commercial paste using bur rubber cup and felt cone on the surface roughness of composite resin restorations. This laboratory experimental research uses a post-test only group design. This study used 24 maxillary 1st incisor teeth restored in Class V and divided into six treatment groups: polishing group using blood clam shell paste with bur rubber cup and felt cone; polishing group using commercial paste with bur rubber cup and felt cone; and polishing group using only bur rubber cup and felt cone. Sample surface roughness testing using a profilometer. Statistical analysis was performed using ANOVA test and Post Hoc LSD (Least Significant Difference) with the degree of significance α=0.05. The results of the One Way ANOVA test obtained a significance value of p=0.000, which showed there was a significant difference between the six treatment groups (p<0.05). The group of samples polished using blood clam shell-based paste and with a rubber cup bur showed the lowest surface roughness values.
