Alginate is a kind of impression material that used in the manufacture of prostheses. Desinfection measures against the alginate mold shortly after molding is a recommended procedure by ADA to prevent bacterial contamination of alpha Streptococcus. The purpose of study is to find out the effect of immersion alginate mold in a solution of chitosan oligomers on the growth of alpha Streptococcus This study carried out on 50 discs of alginate incubated in alpha Streptococcus suspension for 3 minutes at room temperature, then divided into 5 groups, each group consist of 10 alginate discs. Group I is a group of alginate discs incubated in sterilized aquadest solution, group II, III, IV and V are groups of alginate discs incubated in chitosan oligomer 0.02%, 0.01%, 0.005% and 0.1% for 10 minutes at room temperature, then with dilution method and the conter hand tools to do the counting of the number of alpha Streptococcus colonies. The data obtained were Analized with one way anava and post hoc test with LSD. The result showed significant differences between the control and the treatment groups with the concentration chitosan oligomers 0.02%, 0.01%, 0.05%, and 0.1% and between the treatment groups (p < 0.05%). The conclusion is the immersion of alginate mold in chitosan oligomers inhibit the growth alpha Streptococcus, the best inhibitory concentration was 0.1 % and levels of chitosan�s minimum inhibitory was less than 99.9% hence it is bacteriostatic.
