PURPOSE
To investigate the contamination of the dental irrigation systems with Cryptosporidium species in Alexandria, Egypt.
METHODS
Forty water samples from all 20 working dental irrigation machines in a dental center in Alexandria were included in the study. Water samples were taken from the handpieces of dental irrigation machines in all studied units. After filtration through a membrane filter, water sample residues were stained using modified Ziehl-Neelsen staining and examined microscopically for Cryptosporidium spp.
RESULTS
Cryptosporidium spp. was found as a contaminant in 27.5% of water samples taken from dental irrigation machines.
CONCLUSION
This indicates a contamination by the public water supplies to which these dental irrigation machines are connected. This disinfection pitfall may pose an infection risk to those seeking dental care.
目的
研究埃及亚历山大市牙科冲洗系统中隐孢子虫属的污染情况。
方法
本研究纳入了亚历山大市一家牙科中心的 20 台工作牙科冲洗机的 40 份水样。从所有研究单位的牙科冲洗机手机中采集水样。水样通过膜过滤器过滤后，使用改良的齐尔-尼尔森染色对水样残留进行染色，并在显微镜下检查隐孢子虫属。
结果
从牙科冲洗机采集的水样中，发现隐孢子虫属的污染率为 27.5%。
结论
这表明这些牙科冲洗机所连接的公共供水系统受到了污染。这种消毒陷阱可能会对寻求牙科护理的人造成感染风险。
