Abstract

Safe storage times were evaluated for three sterile packaging materials that are commonly used in dentistry. No significant differences were found among packaging materials. Only three packs of 300 produced positive cultures during the 1-year test period. There were no time-related trends. The contamination levels found were within the range that has been reported to occur as a result of inadvertent contamination during unpackaging and transfer of sterile instruments. The findings of this study support the proposal that contamination is event related, not time related; that is, sterile instrument packs remain sterile for at least 1 year unless a specific event causes contamination.

摘要

对牙科常用的三种无菌包装材料的安全储存时间进行了评估。在包装材料之间未发现显著差异。在为期1年的测试期内，300包中只有3包培养出阳性菌。没有与时间相关的趋势。发现的污染水平在据报道因无菌器械拆包和转移过程中意外污染而出现的范围内。本研究结果支持以下观点：污染与事件相关，而非与时间相关；也就是说，无菌器械包至少在1年内保持无菌，除非特定事件导致污染。
