| Abstract |
|
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$^{(R)}$ 수식 이미지 (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$^{(R)}$ 수식 이미지 proves to be a useful and practical method for preventing cross-infections. |
