Abstract

This study aimed to investigate the contamination rate of microorganisms by times after sterilization in mirrors, dental explorers, and pincettes which are the basic tools used in the dental clinic. 60 samples by each tool were used upon packaging them by 10 units. Contamination rate of microorganisms were tested using dry film media(3M Petrifilm Plates) which is a quick check upon collecting 10 samples right after sterilization, at Week 2, 3, 4, 5, and 6. At Week 0 when was right after sterilization, no microorganism was detected in any tools while they were detected in 2 mirrors, 2 dental explorers, and 2 pincettes at Week 6. 2 to 4 colonies on average were detected in mirrors at Week 2 and 4, 1 to 2 colonies in explorers from Week 5, and no colony was found in pincettes until Week 5 but 1 to 2 colonies at Week 6. Based on these results, the needs of effective periods are suggested for the sterilized tools together with their safe usages.

본 연구는 치과에서 사용하는 기본기구인 Mirror, Explore, Pincette에서 멸균 후 시간이 경과함에 따른 미생물 오염도를 알아보고자 하였다. 치과에서 주로 사용하고 있는 Mirror, Explorer, Pincette을 10개씩 포장하여 각 기구별 60개의 샘플을 사용하였다. 미생물 오염도는 멸균직후, 2주차, 3주차, 4주차, 5주차, 6주차에 10개의 샘플을 수거하여 건조필름배지(3M Petrifilm Plates)를 이용하여 검사하였다. 멸균 직후인 0주차에는 모든 기구에서 균이 검출 되지 않았으나, 6주차에서는 Mirror, Explorer, Pincette에서 각각 2개의 기구에서 균이 검출 되었다. Mirror에서는 실험 2주차와 4주차에서 평균 2-4개의 colony가 관찰 되었고, Explorer는 5주부터 평균 1-2개의 colony가 발견되기 시작하였으며, Pincette에서는 5주차까지 colony가 발견되지 않았으나, 6주차에서는 평균 1-2개의 colony가 발견 되었다. 이 결과를 바탕으로 보다 안전한 기구사용과 더불어 멸균기구의 유효기간의 필요성을 제시하고자 한다.
