摘要
目的通过荧光素示踪法探索口腔诊疗中喷溅物的颗粒物特性和污染来源。方法设置水路组和唾液模拟组,分别将荧光素钠溶液加入自供清洁水瓶中和经过导管导入口中,通过沉降结果的对比明确喷溅物的特性以及病原体的来源。结果水路组检测到的荧光素点数量较唾液模拟组更多(P<0.01),且水路组的荧光素点粒径均大于100μm。使用强负压吸引器干预后,荧光素点的数量显著减少(P<0.01)。使用弱负压吸引器干预后,粒径小于100μm的荧光素点占比下降。在模拟不同区段牙齿治疗时牙齿越靠近口腔前部,其喷溅物范围越发散,且数量越多。结论在采取适当的防控措施时,口腔喷溅治疗造成疾病传播的潜在风险可能是可控的。
Objective The purpose of this study was to investigate the particle characteristics and contamination source of dental spatters by fluorescein tracer.Methods In the two study groups,namely the waterline-group(sodium fluorescein solution imported to the dental unit waterlines)and the saliva-group(sodium fluorescein solution flow into the mouth through the catheter),the settling results were compared to clarify the characteristics of spatters and the source of contamination.Results The number of fluorescein dots detected in the waterline-group was more than that in the saliva-group(P<0.01),and the particle size of fluorescein dots in the waterline-group were all larger than 100μm.The number of fluorescein dots was significantly reduced with the intervention of high-volume evacuation(P<0.01).The percentage of fluorescein dots with particle size smaller than 100μm decreased with the intervention of low-volume evacuation.When simulating different sections of dental treatment,the closer the teeth are to the front of the oral cavity,the wider the range of the spatters and the greater the number of spatters.Conclusion The potential risk of disease transmission from dental treatment may be manageable with appropriate control measures.
