摘　　要：目的 :观察牙体治疗前漱口与否对诊室空气中细菌含量的影响。方法 :以需氧菌为空气中细菌含量观察指标 ,采用沉降法收集漱口和未漱口组牙体治疗后诊室的空气样本 ,血琼脂平板需氧培养 48h ,观察形成的细菌菌落数。结果 :牙体治疗前漱口组较未漱口组空气中细菌含量明显降低。口洁素漱口组较饮用水漱口组培养板上形成的菌落小 ,但菌落数无明显差异。结论 :牙体治疗前漱口可明显降低诊室中空气细菌污染 。Objective: To examine the effect of mouthwashing before dental procedure on environmental pollution of microorganism in dental clinic. Methods: Air samples in dental clinic after tooth preparation whether using mouthwashes or not pre operationally were collected and cultured with blood agar plates, the bacteria colonies formed on the plates in different groups were counted as the index for air contamination. Results: Environmental contamination from tooth preparation in dental clinic could be reduced significantly by using mouthwash pre operationally( P <0.05), no differences were found between using drinking water and Kou Jie Su in bacteria colony number ( P >0.05), but the size of the colonies formed on the plates in Kou Jie Su group was smaller than that in drinking water group. Conclusion: Environmental contamination from tooth preparation in dental clinic can be reduced by using mouthwash pre operationally. Combination of the pre operational mouthwashing with vacuum aspirator or ventilation installation may be a better way to control the possible cross infection in dental clinic.
