Abstract:
Objective:To explore the effect of ICX ? tablets on controlling the pollution of dental unit waterlines. Methods:From September 30, 2018 to February 23, 2019, convenience sampling was used to select dental chair unit (DCU) with the dental pulp professional brand of A-dec which was newly put into use in a stomatology hospital for numbering. Using the method of random number table, four DCUs were selected and included in this study, including two in experimental group and two incontrol group. In control group, distilled water was added into two DCUs in dependent water storage tanks. In experimental group, two DCUs independent water storage tanks were added with distilled water and ICX ? tablets. From the first day of clinical use, water samples were collected continuously for 7 days, and the ICX ? tablets group was continuously sampled for 12 weeks for bacterial culture, and the number and qualified rate of colonies were counted. Results:A total of 280 water samples were collected.The number of colonies at the water outlet of the new DCU that used distilled water added with ICX ? tablets as dental unit waterlines was lower than that of distilled water group from the first day, and the difference was statistically significant ( P=0.007) . The qualified rate of colony number at the water outlet of the new DCU that used distilled water added with ICX ? tablets as dental unit waterlines was higher than that of distilled water group from the second day, and the difference was also statistically significant ( P=0.007) . Conclusions:ICX ? tablets can effectively control the pollution of dental unit waterlines and can keep the number of colonies in dental unit waterlines at a low level for a long time, but it still needs to be combined with regular monitoring and enhanced disinfection.
