INTRODUCTION
The microbiological safety and control of the water used in dental practice has a critical importance for avoiding cross-linked infections in the dental office. The aim of this study was to establish coxsackie virus filtration of the water applied to a dental unit.
METHODS
A specific water filter-system was used, to verify the viral load in the outgoing water. The statistical analysis was performedusing the Shapiro-Wilk and t-Student test.
RESULTS
The outcome of the evaluation of the virologic tests shows an excellent capability of virus filtration that attested 99.9999% in the volume analyzed. A statistical difference was found in the bacterial water contamination parameter before and after filtration. (P = 0.000000).
CONCLUSIONS
According to the tests, medical devices applied to a dental unit are able to filter viruses and therefore reduce risk of contamination in the dental office.
引言
牙科操作中使用的水的微生物安全性和控制对于避免牙科诊室中的交叉感染至关重要。本研究的目的是建立一种对牙科器械用水进行柯萨奇病毒过滤的方法。
方法
使用特定的水过滤系统来验证出水的病毒载量。使用 Shapiro-Wilk 和 t-Student 检验进行统计分析。
结果
病毒学检测结果表明，该过滤系统具有出色的病毒过滤能力，在分析的体积中达到了 99.9999%。过滤前后的细菌水污染参数存在统计学差异（P = 0.000000）。
结论
根据测试结果，应用于牙科器械的医疗器械能够过滤病毒，从而降低牙科诊室中的污染风险。
