The aesthetics of fixed denture treatments are important factors that determine the success of the treatment. The optimal esthetic results in the manufacture of crowns and bridges require several considerations such as the size, shape, and color of the denture. The right color is one of the factors that influence the success of fixed bridges (GTJ) from an aesthetic aspect. In this descriptive survey research, the author examined the color of the ceramic metal that would be attached to the patient and compared it to the color guide and then the author distributed a questionnaire to assess the level of knowledge from clinical clerkship students at Prosthodontics Department Universitas Sumatera Utara regarding the procedure in determining the color of dentures. A colorimeter is used as a tool in determining the color accuracy of fixed dentures. The mean difference in color between the fixed denture and the color guide was tabulated and univariate analysis was performed. The results showed no significant color difference between the fixed denture and the color guide. 80,95% of respondents had a good knowledge level in the determining color procedure.

ABSTRACTIntroduction: Brushing of provisional crown material using a toothbrush and abrasive toothpaste induces surface roughness. This study, therefore, aims to determine the difference in surface roughness on provisional crown materials after brushing with soft and medium filament toothbrushes using high and low abrasive toothpaste. Methods: This type of laboratory experimental research employed a pre-test and post-test group design of 40 samples divided into four groups of ten samples each. The groups consisted of Group A (bis-acrylic temporary crown material brushed with medium-filament toothbrush and high-abrasive toothpaste), Group B (bis-acrylic temporary crown material brushed with soft-filament toothbrush and high-abrasive toothpaste), Group C (bis-acrylic temporary crown material brushed with medium-filament toothbrush and low-abrasive toothpaste), and Group D (bis-acrylic temporary crown material brushed with soft-filament toothbrush and low-abrasive toothpaste). The sample brushing method was carried out using a Modified V8-Brushing Machine tool for 2000 cycles at a speed of 120 cycles/minute and a 0.2 N pressure. Results: A profilometer was used to measure surface roughness. The mean value of surface roughness was analyzed by a univariate test, yielding groups A (0.41 µm ± 0.18), B (0.36 µm ± 0.13), C (0.40 µm ± 0.15), and D (0.25 µm ± 0.09). The Kruskal-Wallis Statistical analysis test determined significant differences among test groups. This study indicates that the surface roughness of bis-acryl provisional crown material brushed with soft and medium-filament toothbrushes differed from that with a combination of high and low-abrasive toothpaste p = 0.001 (p < 0.05). Conclusion: Brushing provisional crown materials with a medium-filament toothbrush resulted in a higher roughness value than with a soft-filament toothbrush, and the group that brushed with high-abrasive toothpaste showed higher roughness values than that with low-abrasive toothpaste.

Background: The polishing procedure is an important stage in producing a successful restoration. Polishing involves the use of abrasive materials, and blood cockle shells contain these natural components, such as calcium carbonate, which can be used as a polishing paste. One of the factors that influences the polishing quality is the polishing duration. Purpose: This study evaluated the polishability of a nanohybrid composite using blood cockle shell polishing paste by measuring the surface roughness and gloss value, and by observing the surface qualities based on different polishing times. Methods: Ninety samples of maxillary premolars were immersed in artificial saliva in an incubator at 37°C for 24 h. A total of 45 samples were subjected to a profilometer to observe surface roughness, and the rest were subjected to a glossmeter to observe the composite resin gloss. These included blood cockle shell paste, Prisma Gloss polishing paste, and without paste for 30, 60, and 90 seconds. The data were statistically analyzed using repeated measures ANOVA and post hoc least significant difference (LSD). Results: It showed that the group of 90 seconds had the highest gloss and the lowest surface roughness in the blood cockle shells. The difference was statistically significant (p>0.05). The results of the surface roughness test of the blood cockle shells with a duration of 30 and 60 seconds were found to be not significant (p<0.05). Conclusion: There were significant differences by adding the polishing duration, which decreased the surface roughness and increased the surface gloss, in which the lowest roughness and highest glossiness was found with a polishing time of 90 seconds. The polishability of composite resin restorations in this study obtained the best gloss and smoothest surface results from the longest polishing time duration of 90 seconds with the blood cockle shell polishing paste.

ABSTRACT Introduction: Bis-acryl composite resins are commonly used for temporary crowns but are difficult to polish due to their soft resin and hard filler particles. Well-polished surface on temporary crowns offers benefits like better gingival-health, improved mastication, and better aesthetics. Multi-step aluminum oxide discs and one-step diamond discs are effective for polishing bis-acryl materials. This study aimed to analyze the surface roughness and gloss of bis-acryl provisional crowns before and after polishing with two different polishing systems. Methods: Total of 72 samples (10x2 mm and 16x2 mm) were divided into two groups (I and II) for roughness and gloss analysis. Each group was further subdivided into four sub-groups (IA,IIA,IB, and IIB). Groups IA and IIA were polished using the aluminum oxide multi-step system, while groups IB and IIB were polished using the diamond one-step system. All samples were pre-standardized with abrasive paper #1000 before polishing. Surface roughness and gloss were measured using profilometer and glossmeter before and after polishing. The data were analyzed using paired t-test (p<0.05). Results: After polishing, the surface roughness for the aluminum oxide group was 0.18±0.02, with gloss value of 46.55±1.31. The diamond disc resulted in surface roughness of 0.15±0.02 and gloss value of 51.08±1.76. Statistically significant differences were found in surface roughness and gloss between groups IA and IB (p=0.0001), delta gloss between groups IIA and IIB (p=0.0001). Conclusions: Both polishing systems produced acceptable surface roughness (0.20 μm) and gloss (40-60 GU). However, the diamond one-step system produced a smoother and glossier surface with greater efficiency. KEY WORDS: Bis-acryl, surface roughness, gloss, aluminum oxide, diamond Pengaruh perbedaan sistem pemolesan terhadap kekasaran dan kilap permukaan pada material bis-acryl: studi eksperimental ABSTRAKPendahuluan: Resin komposit bis-acryl sering digunakan untuk mahkota sementara, namun sulit dipoles karena kombinasi resin lunak dan partikel filler keras. Permukaan mahkota yang dipoles memberikan keuntungan dalam perawatan gigi, seperti kesehatan gusi, pengunyahan, dan estetika. Disk aluminium oksida dan disk diamond dianggap efektif untuk pemolesan bahan bis-acryl. Penelitian ini bertujuan untuk mengevaluasi kekasaran dan kilap permukaan bahan mahkota sementara bis-acryl sebelum dan sesudah pemolesan dengan dua sistem pemolesan yang berbeda. Metode: Sebanyak 72 sampel bis-acryl berbentuk disk (10x2 mm dan 16x2 mm) dibagi menjadi dua kelompok (kelompok I dan II) untuk evaluasi kekasaran dan kilap permukaan. Setiap kelompok dibagi lagi menjadi empat sub-kelompok (IA, IIA, IB, IIB). Kelompok IA dan IIA dipoles dengan disk aluminium oksida sistem multi-langkah, sedangkan kelompok IB dan IIB dipoles dengan disk diamond sistem satu langkah. Sebelum pemolesan, semua sampel distandarisasi menggunakan kertas abrasif #1000 dengan rotary grinder. Profilometer dan glossmeter digunakan untuk mengukur kekasaran dan gloss permukaan. Kemudian data dianalisis menggunakan uji t berpasangan (P<0.05).Hasil: Setelah pemolesan, kekasaran permukaan dengan disk aluminium oksida adalah 0,18±0,02 dengan gloss 46,55±1,31. Dengan disk diamond, kekasaran permukaan menjadi 0,15±0,02 dengan gloss 51,08±1,76. Uji T menunjukkan perbedaan signifikan pada kekasaran dan gloss antara kelompok IA dan IB (p=0,0001), serta perbedaan signifikan pada gloss antara kelompok IIA dan IIB (p=0,0001). Simpulan: Kedua sistem pemolesan menghasilkan kekasaran permukaan dan gloss yang dapat diterima, namun disk diamond menghasilkan permukaan yang lebih halus dan mengkilap dengan efisiensi lebih tinggi. KATA KUNCI: Bis-acryl, kekasaran permukaan, kilap, aluminum oksida, diamond
