Abstract:
0bjective: To observe the effects of parotid saliva(PARS), extraparotid saliva(EPS) and purified high molecular weight mucin(MG1) on the aggregation of streptococcus mutans . Methods: PARS, EPS and MG1 were prepared routinely and applied in the cultures of S. mutans Inbritt, S.mutans LM and S.sobrinus OMZ 176 respectively for 2 h. The aggregation of the bacteria was measured spectrophotometrically.Results: The aggregation (%) of S.mutans Inbritt, S.mutans LM and S.sobronus OMZ 176 induced by EPS was 32.80 , 57.87 and 35.46 , that by MGI 25.68, 32.77 and 24.16 , that by PARS 13.52, 22.23 and 16.00, respectively. Conclusion: The effect of MGI on the aggregation of streptoccus mutans is weaker than that of EPS and stronger than that of PARS. The aggregation may be primarily induced by mucins.
