    Abstract
    Introduction : Differences in composition related to filler size, distribution, and initiator in bulk fill composite resins will affect the physical properties of composite resins such as surface roughness and color stability of a restoration. Commercial polishing pastes contain a mixture of synthetic ingredients that can irritate the eyes and skin for repeated use over a long period of time. The purpose of this study was to examine the effect of polishing paste made from blood clam shells on the surface roughness and color stability of bulk fill composite resin. Materials and methods: Blood clam shells were collected and mashed using a ball mill to a particle size of <10 ... m and examined for basic composition and main compounds in blood clam shell. Then polishing paste with 50% blood clam shell is made by combining 5 g blood clam shell powder with 10 g pasta base. A bulk fill composite resin disc sample was prepared using a master cast then polymerized and allowed to stand for 24 hours. The composite resin disc was polished with 3 treatment groups; 1. Polished using blood clam shell paste, 2. Polished with commercial paste, 3. Not polished with paste. The oral cavity simulation procedure was carried out by immersing it to pH 3.5, 7, 10 and stored in an incubator at 37 . Then, the surface roughness (Ra) of each sample was checked using an atomic force microscope and color stability (ΔE) was checked using the eLABor_aid system. One-way ANOVA test was performed to see the effect of blood clam shells on surface roughness and color stability, Post Hoc LSD test to see differences between groups, and Spearman's test to determine the relationship between surface roughness and color stability. Results: The results of the One-way ANOVA test showed that the polishing paste with blood clam shell had an effect on the surface roughness of the composite resin. From the results of the Post Hoc LSD test, there were significant differences between each treatment group. One-way ANOVA test results showed that the polishing paste with blood clam shell had an effect on the color stability of the composite resin. From the results of the Post Hoc LSD test, there were significant differences between each treatment group. The results of Spearman's test showed that there was a significant relationship between surface roughness and color stability in the composite resin polished with paste and there was no significant relationship in the group that was not polished with paste. Conclusion : There is an effect of polishing paste made from blood clam shells on the surface roughness and color stability of bulk fill composite resin.
     
    Pendahuluan : Perbedaan komposisi yang berhubungan dengan ukuran filler, distribusi, dan inisiator pada resin komposit bulk fill akan mempengaruhi sifat fisis dari resin komposit seperti kekasaran permukaan dan stabilitas warna suatu restorasi. Pasta polishing komersial memiliki campuran kandungan sintesis yang dapat menyebabkan iritasi pada mata dan kulit untuk pemakaian berulang dalam jangka waktu lama. Tujuan penelitian ini adalah melihat pengaruh pasta polishing berbahan dasar cangkang kerang darah terhadap kekasaran permukaan dan stabilitas warna resin komposit bulk fill. Bahan dan cara : Cangkang kerang darah (CKD) dikumpulkan dan dihaluskan menggunakan ballmill sampai ukuran partikel <10 μm dan diperiksa komposisi dasar dan senyawa utama pada CKD. Kemudian pasta CKD dengan konsentrasi 50% dibuat dengan menggabungkan serbuk cangkang kerang darah 5 gr dengan basis pasta 10 gr. Dilakukan persiapan sampel disk resin komposit bulk fill dengan menggunakan master cast lalu dipolimerisasi dan didiamkan selama 24 jam. Resin komposit disk dipoles dengan 3 kelompok perlakuan ; 1. Dipoles dengan menggunkan pasta CKD, 2. Dipoles dengan pasta komersil, 3. Tidak dipoles dengan pasta. Dilakukan prosedur simulasi rongga mulut dengan merendamkan sampe ke pH 3,5, 7, 10 dan disimpan di dalam inkubator dengan suhu 37 ℃. Kemudian dilakukan pemeriksaan kekasaran permukaan (Ra) masing-masing sampel dengan menggunakan atomic force microscope dan dilakukan pemeriksaan stabilitas warna (ΔE) dengan sistem eLABor_aid. Dilakukan uji One-way ANOVA untuk melihat pengaruh cangkang kerang darah terhadap kekasaran permukaan dan stabilitas warna, uji Post Hoc LSD melihat perbedaan antar kelompok, dan uji Spearman’s untuk mengetahui hubungan antara kekasaran permukaan dan stabilitas warna. Hasil : Hasil uji One-way ANOVA menunjukkan pasta polishing CKD mempunyai pengaruh terhadap kekasaran permukaan resin komposit. Dari hasil uji Post Hoc LSD, terdapat perbedaan yang signifikan antara tiap kelompok perlakuan. Hasil uji One-way ANOVA menunjukkan pasta polishing CKD mempunyai pengaruh terhadap stabilitas warna resin komposit. Dari hasil uji Post Hoc LSD, terdapat perbedaan yang signifikan antara tiap kelompok perlakuan. Hasil uji Spearman’s menunjukkan terdapat hubungan yang signifikan antara kekasaran permukaan dan stabilitas warna pada resin komposit yang dipoles dengan pasta dan tidak terdapat hubungan yang signifikan pada kelompok yang tidak dipoles dengan pasta. Kesimpulan : Terdapat pengaruh pasta polishing berbahan dasar cangkang kerang darah terhadap kekasaran permukaan dan stabilitas warna resin komposit bulk fill.
