摘要

Objective To understand the cleaning quality of dental handpieces in Suzhou City, analyze the relevant factors that influencing cleaning effect.Methods A cross-sectional study was performed with the proportional system sampling method, questionnaires were adopted to investigate the cleaning location, cleaning method and process of dental handpieces, the ATP fluorescence detection method was conducted to detect cleaning quality.Results In 10 administrative regions of this city, a total of 72 medical institutions were selected, 25 were public medical oral diagnosis and treatment institutions, 47 were private clinics.Cleaning effect of automatic handpiece cleaning machine was better than traditional manual cleaning (unqualified rate :3.95% vs 11.96%, P<0.05), unqualified rate of handpieces cleaned by cleaning personnel without inadequate knowledge was higher than that by personnel with adequate knowledge(14.88% vs 3.57%, P<0.05).Qualified rate of cleaning: different cleaning locations ranged from 5.00% to 11.23%, cleaning equipment was inadequate and sufficient 11.89% and 7.29% respectively, cleaning personnel were not designated and designated 12.16% and 9.83% respectively, but the difference were not statistically significant (all P>0.05).The quality of cleaning of handpieces could be improved if waiting time of cleaning ≤30 minutes, enzymes were used during cleaning, and purified water was used at the end rinse(all P<0.05);whether there was drying process and used lubricant, difference were both not significant.Conclusion Using automatic handpiece cleaning machine, cleaning personnel with adequate knowledge, cleaning waiting time ≤30 minutes, enzyme use during the cleaning process, and purified water use at the end rinse can improve the quality of cleaning of dental handpieces.%目的 了解苏州市牙科手机清洗质量,分析影响清洗效果的相关因素.方法 采用等比例系统抽样法对该市医疗机构进行横断面调查,采用调查表对手机清洗场所、清洗方式等环节和流程进行调查,ATP生物荧光检测法检测手机的清洗质量.结果 在全市10个行政区范围内共抽检医疗机构72所,其中公立医疗口腔诊疗机构25所,民营单位47所.使用全自动手机清洗机进行清洗的效果好于传统手工清洗(不合格率分别为3.95% vs 11.96%),知识掌握不足的清洗人员清洗不合格率高于知识掌握好的清洗人员(14.88% vs 3.57%),差异均有统计学意义(均P<0.05).清洗不合格率:不同清洗地点为5.00%~11.23%,清洗设备不足和充足时分别为11.89%、7.29%,清洗人员不固定和固定分别为12.16%、9.83%,但差异均无统计学意义(均P>0.05).手机清洗等待时间≤30 min、清洗过程中使用酶剂、终末漂洗使用纯化水可以改善手机清洗质量(均P<0.05);有无干燥过程和是否使用润滑油等因素比较,差异无统计学意义.结论 使用全自动手机清洗机,清洗人员知识掌握充分,清洗等待时间≤30 min、清洗过程中使用酶剂、终末漂洗使用纯化水能提高牙科手机的清洗质量.
