This study is a temporary crowns and the period you want to avoid the exposure of the coffee girl polymerization types is difficult given the temporary tolerance by producing resin. 1. Change of brightness (L*) edge in time increases, distilled water, Americano, Cafelatte, Vanillalatte was reduced to a significant level of brightness (p<.001). The most significant decrease in brightness of the Americano, which tend to grow out of a Cafelatte, Vanillalatte, which was followed by distilled water. 2. Change of redness (a*) edge in time tend to increase saturation increases, the redness value of Americano, Cafelatte, redness value was a statistically significant difference in distilled water and Vanillalatte (p<.05) was not significant. 3. Change of yellowness (b*) edge in time tend to increase saturation increases, the yellowness value of Cafelatte, Vanillalatte, Americano, except for distilled water at the saturation of yellowness value were no statistically significant (p<.05). 4. Change of color difference (□E*) in order of (Americano>Cafelatte>Vanillalatte) as time of immersion increases change of color difference appear and no statistically significant (p<.05). Americano, the edge, since there can be more than chrominance is 3.3 uses station than a Vanillalatte, Cafelatte and discoloration when edge in 28, since even in the one to two difficult to distinguish with the naked eye as a discoloration. It was no difference statistically in color difference (□E*) value in distilled water (p>.05).

The purpose of this study was to investigate the differences in health belief related to vaccination among dental hygiene students, identify the factors affecting hepatitis B vaccination, and provide basic data for health education concerning hepatitis B prevention. Hepatitis B vaccination was positively correlated (r=0.179, p=0.003) with seriousness of believing that hepatitis B would affect psychological, physical, and social activities and negative correlation (r=-0.183, p=0.002) was also found between perceived barriers related to hepatitis B. As for the factors affecting hepatitis B vaccination, juniors were 0.39 times (95% confidence interval [CI]=0.21, 0.71) more likely to have it affected than seniors and those who were more serious, and who had greater barriers were more likely to have it affected-1.80 times (95% CI=1.29, 2.52), 0.61 times (95% CI=0.41, 0.90) respectively (p<0.05). It is therefore urgent to develop a program within a curriculum that can begin with freshmen along with specific education with the objective of obliging dental hygiene students to receive hepatitis B vaccination. It is also necessary to provide consecutive sessions of education rather than one-time education and to develop a specific plan for obligatory hepatitis B vaccination through correct and thorough education.
