Resin composite is dental material filling that is commonly used in dentistry which has good physical properties, mechanical and aesthetics. The properties that have an important role in the resistance of the composite resin surface hardness which directly involved when contact with food, drink and salivary. The purpose of this research is to evaluate the effect of carbonated soft drink and alcoholic beverages on the surface hardness of nanofiller composite resin.The method used in this research is post test only control group design. Samples were made using the mold made of stainless steel, with diameter of 6mm and tick of 2mm, composite was manipulated according to the manufacture’s instructions, and then immersed in aquades, carbonated soft drink and alcoholic beverages for 18 hours in a temperature of 37ºC. Samples were tested using Vickers Hardness Test. Data analysis using Kruskal-Walis test.The result show that the nanofiller composite resin which immersed in alcoholic beverages has higher surface (81,04±10,44 VHN), whreas the composite which immersed in aquades and carbonated soft drink has the surface hardness (70,20±16,6 dan71,10±15,96 VHN). The result of data analysis showed that the data are not distributed normally and showed a significant value of p>0,05. From this research can be concluded that there is no significant differences in surface hardness of nanofiller composite resin which immersed in carbonated soft drink and alcoholic beverages. Keywords: Resin Komposit, nanofiller, surface hardness, mechanical properties.

materials have character that absorb water it is imbibition that can affect the dimensional stability when immersed in disinfectant . The purpose of this study is to see the effect of imbibition at alginate impression material immersed in a disinfectant solution of Sodium Hypochlorite .The method used was experimental with pretest and posttest with control group design . The mold were diameter of 28 mm and height 18 mm .the impression were immersed in sodium hypochlorite 0.5 % and 1 % for 3 minutes , 5 minutes and 10 minutes . Imbibition weight calculation is done by using digital scales.The results showed that the presence of imbibition on impression material alginate that immersed in Sodium Hypochlorite solution for 3 minutes , 5 minutes and 10 minutes . Statistical Test Two Way Repeated Measure ANOVA showed a significant difference ( p< 0.05 ) in minutes imbibition , while the concentration of the solution had a significant difference ( p > 0.05 ) .The conclusion of this study is the alginate impression material has the effect of imbibition to immersion Sodium Hypochlorite solution. Keywords : hydrocolloid Alginate , Sodium Hypochlorite , imbibition effects , immersio

Parents’ knowledge is very important in keeping children’s mouth and teeth clean especially on disability children. According to the researcher’s survey, it hasn’t been conducted a research yet about oral hygiene indeks of deaf children. The objective of this research is to determine the correlation of parents’ knowledge with oral hygiene indeks of 9-12 years old deaf children at extraordinary schools in Padang”. The design of this research is observational analytic with cross sectional approach. Population of this research is all deaf children at 5 extraordinary schools who are the most ages are 9-12 years old. They are 34 children whom are selected by using total sampling technique. Time of the research is in March 2016. The research instruments are questionnaire and oral hygiene status. Univariate analysis is shown in the form of frequency distribution tables and bivariate analysis is by using chi-square test with 95% α = 0.05 level of trust. Research findings showed more than a half (73,5%) children had not good level of mouth and teeth clean; only a small percentage (20,6%) parents had high knowledge; and there was no significant correlation between parents’ knowledge and oral hygiene indeks simplifield (OHI-S) of 9-12 years old deaf children at extraordinary. PValue = 0.187. Keywords : Parents’ knowledge, oral hygiene indeks of deaf children
