摘　　要：目的研究口臭口腔微生物区系组成,为口臭治疗提供依据。方法采用稀释平板测数法对需氧和厌氧细菌、真菌、放线菌分别进行计数。结果非口臭口腔好氧细菌数量(1180±380)和厌氧细菌数量(680±100)分别低于口臭口腔好氧细菌数量(7200±800)和厌氧细菌数量(12520±120),差异有统计学意义(P<0.01),且口臭口腔以革兰阳性菌和杆菌占优势,非口臭口腔真菌数量低于口臭口腔真菌数量,两者差异无统计学意义(P>0.05)。口腔中没有检出放线菌。结论口臭患者口腔微生物多样性高于非口臭组,可以通过调整口腔微生态改善口臭。Objective To study the composition of oral microflora in halitosis and provide basis for bad breath treatment. Methods The dilution plate count method was used to count the aerobic and anaerobic bacteria,fungi and actinomycetes respectively. Results The counts of aerobic bacteria（ 1180 ± 380） and anaerobic bacteria（ 680 ±100） in non-halitosis specimens were lower than those of aerobic bacteria（ 7200 ± 800） and anaerobic bacteria（ 12520 ± 120） in halitosis specimens respectively,with significant statistical significance（ P〈 0. 01）. Gram-positive bacteria and bacilli were predominant in halitosis specimens,and the number of fungi in non-halitosis specimens was less than that in halitosis specimens,but with no statistical significance（ P 〉0. 05）. No actinomycetes were detected in oral cavity. Conclusion The oral microbial diversity in halitosis patients is higher than in the non-halitosis group. Bad breath may be improved through adjusting the oral microecological balance.
