Abstract

Background. To repair indirect composile by direct composite can cause growlh of bacterial colonization because of the difference roughness surface. Purpose. The aim of this study was to know the growth of Streptococcus mulans colony and the roughness surface of direct and indirect composite. Msterials and Method. The samples of 25mm length, 2mm width, and 2mm in thickness both direct and indirect composite were measured by surfuce roughness lesler. Samples immersed in saliva for one hour, then the samples were pul into Streptococcus mutans sttspension, incubated for 24 hours at 37'C, and then counted the amount of Streptococcus mutans colony. Results. The data results were tatistically,analyzed by using Independent T-test and Pearson Correlation test, The results showed a significance difference of Streptococcus mutans colony and the roughness surface between direct and indirect composite. Conclusion. The growth of Streptococcus mulans colony and the roughness surface of direct composite is higher than indirect composite.
