초록

본 연구는 미생물의 배양을 통해 임상적으로 효과적인 air/water syringe의 소독법을 조사할 목적으로, 치과 병원에서 사용하는 10개의 AWS tip을 사용하였다. 실험군은 6개 군으로 나누어 실험을 3번씩 반복하여 180개의 샘플을 얻었다. 1군은 소독하지 않은 경우, 2군은 물에 적신 거즈로 큰 오염물만 제거한 경우, 3군은 78% 에탄올 스펀지로 10초간 소독한 경우, 4군은 78% 에탄올 스펀지로 20초간 소독한 경우, 5군은 1 : 100으로 희석한 High Level Disinfectant$^{(R)}$을 적신 스펀지로 20초간 소독한 경우, 6군은 가압증기멸균한 경우이다. 1군과 2군은 4, 5, 6군보다 유의하게 높은 미생물집락형성을 보였다(p < 0.05). 또한 4, 5, 6군은 미생물 집락이 나타나지 않았다. 에탄올과 High level Disinfectant$^{(R)}$를 사용하여 AWS tip을 20초 이상 소독하는 것은 가압멸균법이나 일회용 tip의 사용이 가능하지 않은 경우 교차감염 예방을 위해 유용한 방법이 될 수 있다.

This study aims to investigate contamination level and effective clinical disinfection methods of dental air/water syringes (AWS) by using microbial incubation. This study used AWS of ten dental unit chairs of Hospital. Total 180 samples were obtained. There are six groups of samples: non-sterilized (group 1), sanitized with wet-gauze (group 2), sanitized with 78% ethanol sponge for 10 seconds (group 3), sanitized with 78% ethanol sponge for 20 seconds (group 4), sanitized with 1 : 100 diluted High Level Disinfectant$^{(R)}$ (group 5), autoclaved (group 6). Group 1 and 2 showed statistically significant level of CFUs than Group 4, 5 and 6 (p < 0.05). Group 4, 5 and 6 did not show any noticeable CFU. Sanitizing AWS tips with ethanol and High level Disinfectant$^{(R)}$ proves to be a useful and practical method for preventing cross-infections.
