Background: The prevalence of ECC (Early Childhood Caries) is still problem in Indonesian, especially in children with special needs. Unstable economic development leads to a poorer economic situation and may have an impact on increasing the prevalence of ECC. This study aimed to investigate the Caries Status of ECC in children with special needs and its association with VRFLRGHPRJUD¿ DQG SDUHQWDO VRFLRHFRQRPLF FLUFXPVWDQFHV LQ 6HPDUDQJ Central Java, Indonesian. Method: This research was conducted in SDLB using questionnaire and Using World Health Organization for diagnosis of caries. Informed consent from parents was obtained. The study sample was 21 children aged 3-6 years which consisted of 12 boys and 9 girls. Data were tested by Spearman correlation. . Result:The result showed that 85.7% of the children had ECC.

Background: Tooth development during the embryonic period is a complex process that needs enough nutrition for the formation of healthy dental tissue. Kallikrein-related peptidase-4 (KLK-4) is a serine proteinase secreted by ameloblast during transition and maturation stages in the amelogenesis process which functions to degrade protein matrices so enamel could reach the final hardness. Pregnancy milk contains various nutrients that can increase KLK-4 expression of ameloblast cells in the tooth development. This study aims to determine the impact of pregnancy milk against the KLK-4 expression of ameloblast cell in the tooth development process. Method: 12 pregnant female mice (Mus Musculus L.) divided into control group (given sterile aquadest) and treatment group (given pregnancy milk + sterile aquadest) for 18 days then the tooth germ was taken. Samples were stained to see the KLK-4 expression. Data were analyzed using an Independent sample t-test. Result: Our study showed that the average amounts of KLK-4 expression in the treatment group are higher than the control group. Based on the Independent sample t-test statistic methods, there is a significant difference with the value of p=0,017. Conclusion:The pregnancy milk could influence the Kallikrein-related peptidase-4 (KLK-4) expression of ameloblast cell in the mice fetus's tooth development.
Background:This study evaluated the efficacy of a one step adhesives in reducing microleakage after water storage and thermocycling. Method: eighteen freshly extracted caries-free human premolars were used. The teeth were randomly divided into two groups; Group I: control etch adhesive (GC),Group II: G Bond One step adhesive (GC) The teeth were restored using helioseal Vivadent. Group II Each layer was cured using the Spectrum 800 curing light (Dentsply/Caulk) for 20 seconds at 600mW/cm2. The teeth were stored in artifisial saliva for 7 days in incubator. Samples were thermocycled 250x between 5°C and 55°C with a dwell of 30 seconds, then placed in a 0.5% methylene blue dye solution for 24 hours at 37°C. Samples were sectioned longitudinally and evaluated for microleakage at the occlusal and gingival margins under a microscope at 40x magnification. Dye penetration was scored: 0: no microleakage visible, score 1: microleakage up to half of the fissure, score 2: microleakage more than half of the fissure. Result: Mann-Whitney test was used to demonstrate significantly more dye penetration in Group I and Group II. When comparing the scores for two group, the Mann Whitney test showed no significant difference in dye penetration for etch and One step adhesive (p>0.05). Conclusion: Based on the results of this study, it can be concluded that etch and one step adhesive in the fissure sealant no significant difference to reduce of microleakage in study in vitro.
Background: Enterococcus faecalis is generally found on the failure of root canal treatments. Zinc oxide propolis is believed to have an antibacterial effect on that bacteria. This research aimed to compare bacteriostatic effect of zinc oxide eugenol (ZOE) and zinc oxide propolis (ZOP) as the sealer materials of root canal.Method: This was an experimental research with post-test only control group design with two different groups (ZOE and ZOP). Culture of Enterococcus faecalis bacteria was smeared on Blood Agar Plate media with six times replication per group and kept inside incubator for 24 hours. The result was obtained from the inhibition zone formed around the pasta.Result: The average result of ZOE and ZOP was 27.7 mm and 13.45 mm respectively. Normality test using Shapiro-Wilks showed that data was normal (p>0.05). Then, the data was analysed using Independent Samples T-test. The result showed that there was different inhibition zone between ZOE group and ZOP group (p<0.05).Conclusion: Based on the result, it can be concluded that ZOP has lower antibacterial effectiveness of the Enterococcus faecalis than ZOE.
Struktur enamel terdiri dari 96 % bahan anorganik, 4% bahan organik, air dan jaringan fibrosa. Ikan laut memiliki banyak kandungan seperti Kalsium, Taurine, Omega 3, PUFAs, Vitamin A, Vitamin D, dan Fluorida yang memiliki fungsi dapat meningkatkan kekerasan enamel gigi. Penelitian ini bertujuan untuk mengetahui pengaruh konsumsi serbuk nanopartikel ikan laut terhadap kekerasan enamel gigi anak mencit (mus musculus).Metode penelitian ini menggunakan jenis penelitian True Experimental dengan rancangan penelitian menggunakan Post Test Only Control Design, terdiri dari 2 kelompok yaitu kelompok kontrol diberi pakan normal dan kelompok perlakuan diberi serbuk nanopartikel ikan laut dengan dosis 2,17 mg / 0,5 ml. Sampel yang digunakan adalah 16 ekor anak mencit kemudian masing-masing anak mencit diambil gigi insisivus. Selanjutnya gigi anak mencit dilakukan uji kekerasan Micro Vickers Hardness Tester, kemudian dianalisa dengan uji statistic. Hasil penelitian menunjukkan bahwa terdapat perbedaan signifikan antara kelompok perlakuan dan kelompok kontrol dengan signifikasi Independent T-test 0,000 (p0,05) pada rahang atas. Kesimpulan yang diperoleh adalah pemberian serbuk nanopartikel ikan laut dapat meningkatkan kekerasan enamel gigi secara signifikan dalam proses tumbuh kembang gigi janin mencit. Kata kunci : kekerasan enamel gigi; serbuk nanopartikel ikan laut; micro vickers hardness tester
