Pengaruh Teknik Wet dan Dry Polishing Menggunakan Pasta Polishing Berbahan Dasar Cangkang Kerang Darah 25% terhadap Kekasaran Permukaan Restorasi Resin Komposit Nanohybrid (In Vitro)

Abstract

One of the parameters assessed in determining the success of a dental restoration is the level of smoothness of the restoration surface. The surface roughness of composite resin is influenced by several intrinsic and extrinsic factors. Extrinsic factors relate to methods at the finishing and polishing stages, such as materials, tools and polishing techniques. The use of polishing paste at the polishing stage can produce a smooth and shiny restoration surface. Apart from that, there are two types of polishing techniques, namely wet and dry polishing. The dry technique can produce heat which can increase the surface roughness of the restoration. The aim of this research was to determine the differences in the effect of wet and dry polishing techniques on nanohybrid composite resin restorations polished with blood cockle shell paste (Anadara granosa) and commercial paste on surface roughness. This laboratory experimental research uses a post-test only group design. This study used 24 first class V restored maxillary incisors and were divided into four treatment groups, namely the polishing group using shellfish paste using wet polishing techniques and dry polishing techniques; and the polishing group used commercial paste with wet polishing and dry polishing techniques. Sample surface roughness testing using a profilometer. Statistical analysis was carried out using the ANOVA test and Post Hoc LSD Test with a significance level of =0.05. The results of the One-Way ANOVA test obtained a significance value of p=0.000, which showed that there were significant differences between the four treatment groups (p<0.05). The group of samples polished using blood clam shell-based paste and using the wet polishing technique showed the lowest surface roughness values.
