The purpose of this study is to evaluate the inhibitory effects of Resina Pini against Streptococcus mutans (S. mutans) that is one of the major causes of dental caries and oral diseases. Topically applied Resina Pini (RP) would be incorporated in saliva and thus the factor associated with water solubility should be considered. In this paper, therefore, effects of various treatment for RP and activities of water extracts from unprocessed and processed RP were compared. The crude RP (RP1) and the recrystallized RP (RP2) in ethanol solution showed strong antimicrobial activities (d.>15mm) against S. mutans. All RP samples exhibited considerable inhibitory effect against glucosyltransferase produced by S. mutans (IC50=91.2 to 276.2 ㎍/ml). The very considerable increase in cellular permeability of S. mutans was observed with RP1, RP2 and their water extracts. These results suggest that RP1 and RP2 may be a potential source for pharmaceutical products used for prevention and/or treatment of dental caries and periodontal disease.
