ABSTRACT
Objective:
To study the effect of methylene blue on the metabolism of reactive oxygen and acid production of Streptococcus mutans .Methods:
Streptococcus of cricetusa, rattusb, mutansc, sobrinsd and mutans e,f and g were exposed to methylene blue at 2.5?10 -4 g/L for 1 h. The metabolism of reactive oxygen and acid production were detected by electron spin trapping method and gas chromatography respectively.Results:
Electron spin resonance (ESR) spectrums of DMPO-O - ? 2 and DMPO-OH ? were observed in Streptococcus mutans cultured in glucose fluid, but were not found in those exposed to methylene. The total of acid production by Streptococcus mutans incubated with glucose + methylene blue were significantly lower than that with single glucose.Conclusion:
Methylene blue may inhibit oxygen species metabolism and acid production of Streptococcus mutans , it may be used as a kind of dental caries prevention agent.
