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.
