摘　　要：目的:比较浓缩含漱法、非刺激性唾液法和棉拭子法对高龋和健康人群口腔唾液中变形链球菌检出率的影响。方法:对60例高龋患者和60例无龋者分别用棉拭子法、非刺激性唾液法和浓缩含漱法进行取样,采用轻唾选择培养基对变形链球菌进行培养,结合显微镜观察对3种方法收集到的变形链球菌进行鉴定,并用SPSS 22.0对数据进行统计学分析。结果:3种采样方法在高龋者中检出率分别为93.33%、96.67%、91.67%,无龋者中检出率分别为56.57%、58.33%、48.33%,无统计学显著性差异。结论:3种方法口腔唾液取样一致性较好。其中,棉拭子法采集到的唾液具有良好的代表性。Objective： To compare the detection rate of oral Streptococcus mutans in caries--active and healthy pa- tients by concentrated rinse sampling, saliva collection, and cotton swab methods. Methods： The samples were col- lected from 120 patients with cotton swab, saliva collection, and concentrated rinse methods. Streptococcus mutans were cultured in Murashige ＆ Skoog medium, and verified with microscope. The difference in various methods were analyzed by SPSS22.0. Results： The detection rates of three methods were 93.33%, 96.67%, and 91.67X in caries--active people, and 56.57%, 58.33%, and 48.33% in healthy people. Conclusion： There is no signifi- cant difference among three methods（P〉0.05）. Cotton swab sampling method is the representative method in clin- ical for its simple, reliable and convenient characteristics.
