摘　　要：目的研究健康青少年口腔优势菌产生过氧化氢的能力。方法采用过氧化物酶法,在体外测得健康青少年口腔优势菌产生过氧化氢的量。结果在需氧条件下,能产生过氧化氢,产生的量与细菌的生长速度成正比;在厌氧条件下,未测得过氧化氢的产生。结论健康青少年口腔优势菌产生过氧化氢的能力强于S.sATCC10556(P<0.05)Objective To study the capability of predominant bacteria producing H2O2 in oral cavity of healthy adolescents. Method In the liquid medium, the quantity of H2O2 that predominant bacteria in oral cavity of healthy adolescents was measured by the method of peroxidase. Result H2O2 had been produced under aerobic condition and the quantity was proportional to the growth rate of bacteria. No H2O2 was detected under anaerobic condition. Conclusion The capability of the predominant bacteria in oral cavity of healthy adolescents to produce H2O2 is better than that of S. s ATCC 10556 （P 〈 0.05）.
