摘要

背景:牙科设备水管(DUWL)将水输送到牙科设备中的不同手机。DUWL 中的水是从一个容器中提取的,在一个封闭系统中循环。牙科用水的质量相当重要,因为病人和牙科工作人员经常接触到牙科设备产生的水和气溶胶。从 DUWL 流出的水可能是牙科医护人员和患者的潜在感染源:2019 年 12 月,对金奈 20 家牙科诊所的 60 份水样进行了体外研究。根据 ADA 指南,从牙科诊所的三个不同来源收集水样。采用琼脂平板法对采集的样本进行了评估,以确定是否存在曲霉菌、不动杆菌、铜绿假单胞菌和军团菌。数据使用 SPSS 软件 20 版进行分析:结果:军团菌是最常见的微生物,在三通注射器中的感染率为 70%,在洗牙器和气切器中的感染率为 50%,其次是铜绿假单胞菌和不动杆菌,在洗牙器和气切器中的感染率为 10%,曲霉菌在三通注射器中的感染率为 10%:大多数牙科诊所都受到曲霉菌、军团菌、铜绿假单胞菌和不动杆菌的污染,这对患者和牙医都构成了严重威胁。

Microbial Contamination of Dental Unit Waterlines among Dental Clinics of India- An In vitro Study.

Background: Dental Unit Water Line (DUWL) deliver water to different handpieces in a dental unit. The water in DUWL circulates in a closed system, where it is taken from a container. The quality of dental water is of considerable importance since patients and dental staff are regularly exposed to water and aerosols generated from dental equipment. Output water from DUWLs may be a potential source of infection for both dental health care personnel and patients.

Aim: To assess the microbial contamination in the DUWL among dental clinics in Chennai.

Materials and methods: An in vitro study was conducted on 60 water samples from 20 dental clinics in Chennai in December 2019. Water samples were collected from three different sources of the Dental unit according to ADA guidelines. The collected samples were assessed for the presence of Aspergillus, Acinetobacter, Pseudomonas aeruginosa, and Legionella by agar plate method. The data were analysed using SPSS software version 20.

Results: Legionella was the most prevalent microorganism with 70% prevalence in a three-way syringe and 50% in scaler and airotor, followed by Pseudomonas aeruginosa and Acinetobacter with 10% prevalence in scaler and airotor and Aspergillus with a prevalence of 10% in the three-way syringe.

Conclusion: Most of the dental units were contaminated with Aspergillus, Legionella, Pseudomonas aeruginosa and Acinetobacter which pose a serious threat to the patients as well as the dentists.
