"Flouride intrusion into enamel surface is one of the important factors of success in topical flouridation. Objective: to compare EDX and flourescence measurement methods of flouride intrusion into enamel surface after anchovy application. Methods: 5 extracted impacted third molars were immersed in sterile saline solution for 24 hours. The buccal surfaces of the teeth were painted with nail varnish, and a window of 5 mm2 at the center of each surface was left unpainted. Dried anchovies from the market were heated and powdered, and 5 g of this anchovy powder was diluted in 100 ml deionized distilled water to prepare an anchovy solution. The teeth were immersed in the anchovy solution for 5 min twice a day with 3 hours intervals. Immersions were repeated for 9 days. After immersion, the teeth were cut transversally through the window. The occlusal portions of the specimens were prepared for microscopic slides at ± 40um thickness. The cervical portions of the teeth were used as EDX specimens. Olympus BX41TF Fluorescence microscope was used to measure flourescence bandwidth. LEO scanning electron microscope with micro analyzer was used to measure flouride intrusion. Increment steps of 5um from outer edge of the enamel to inner side were used as the points of EDX analysis. Paired t-test was used to analyze the intrusion results. Results: Flouride intrusion depth measured using the flourescence method was 11.49 ± 0.71 um, while from the results of EDX analysis the average depth of flouride intrusion was 20.24 ± 0.57 um. Statistical analysis showed significant difference between the two methods. Conclusion: Intrusion measurement using EDX analysis gives higher flouride intrusion than the flourescence method."

"SIK modifikasi resin dapat mengalami penurunan kekerasan permukaan pada pH kritis rongga mulut 5,5 yang dapat dicegah dengan pemberian ion kalsium dan fosfat. Ion tersebut bersumber dari CPP ACP. Pengaplikasian CPP ACP pada SIK modifikasi resin diketahui mampu mencegah terjadinya penurunan kekerasan permukaan SIK modifikasi resin. Saat ini telah ada penggabungan propolis pada CPP ACP yang bertujuan untuk meningkatkan sifat antibakteri tetapi diketahui penambahan propolis mengurangi pelepasan ion kalsium dan fosfat dari CPP ACP sehingga berpengaruh terhadap kemampuannya dalam melindungi SIK modifikasi resin dari penurunan kekerasan permukaan. Namun belum diketahui efek pengaplikasian CPP ACP yang ditambahkan propolis terhadap kekerasan permukaan SIK modifikasi resin.Tujuan: penelitian ini bertujuan untuk membandingkan pengaruh aplikasi pasta CPP ACP dengan dan tanpa kombinasi propolis terhadap kekerasan permukaan semen ionomer kaca modifikasi resin.Metode: Tiga puluh spesimen semen ionomer kaca modifikasi resin berbentuk silinder berukuran 6 x 3 mm, di polimerisasi menggunakan LED curing unit irradiansi 700 mW/cm2, selama 20 detik kemudian disimpan selama 1 hari kering dalam inkubator.

Background: GIC as a restorative material has the ability to chemically bond to the structure of teeth and the ability to release fluoride so that it is suitable for use in patients with a high caries risk but has poor mechanical strength. Modification of GIC restorative materials with combination with bioactive materials to obtain benefits such as increasing mechanical properties, antibacterial properties and remineralization potential has been mentioned in some research literature. In this study, Carboxymethyl-chitosan (CMC) is added to the powder phase of conventional GIC to increase the compressive strength. Objective: to analyze the influence of modified GIC with the addition of CMC on compressive strength and surface morphology. Methods: Thirty holes in a cylindrical acrylic mold, each hole has a diameter of 4 mm and thickness of 8 mm, were filled with conventional GIC restorative material (FUJI IX, GC corp, Japan), modified GIC with 5% CMC and 10% CMC added in the powder phase. The samples were divided into 3 groups: control group GIC (n=10), GIC-CMC 5% group (n=10) and GIC-CMC 10% group (n=10). The compressive strength measurement performed with Universal testing machine (Tensilon RTG-10Kn, A&D, Japan), and were calculated according to the following equation: CS= P/(πr2)

Where P is the maximum load and r is the radius of the cylinder-shaped specimen

Statistical analysis was done by One-Way ANOVA and Post hoc Bonferroni (p<0.05). The surface morphology of the material modification of GIC-CMC and control group was observed using the Scanning Electronic Microscope (EVO MA-0, Zeiss, Germany).

Results: There is a significant difference between the GIC-CMC 5% and GIC-CMC 10% modification groups and the control group (One-Way ANOVA; p<0.05). Based on the Post Hoc Bonferroni (p<0.5) test there is a significant difference in compressive strength in SIK-CMC modification materials of 5% and SIK-CMC of 10% with the SIK control group. Modification of SIK with CMC affects morphological changes in the form of reduced porosity and increased fractures along with the addition of CMC percentage.Conclusion: Modification of GIC with CMC addition reduces compressive strength with the lowest average yield at 10% CMC addition. The surface porusity of SIK modification material with the addition of CMC tends to decrease and increase the surface of cracks that widen along with the addition of CMC percentage."
