| Objective To assess the water disinfection effect of an independently developed external waterway disinfection device for dental unit waterlines by comparing changes in the number of bacterial colonies before and after water disinfection. Method Design and manufacture of waterlines disinfection for dental unit, and five dental units were randomly selected, the programme control of the disinfection device was used to achieve the disinfection process. The bacterial colony counts before and after disinfection were compared by collecting water samples from the outputs of the high-speed air driven handpiece and three purpose spray gun, and the paired t-test was applied to conduct the statistical analysis. Result The water line disinfection for dental unit was successfully produced. After using the automatic disinfection device to disinfect the waterline, the total number of bacterial colonies in the water samples in the outlet of the high-speed air driven handpiece and three-purpose spray gun was significantly reduced relative to the pre-disinfection period, which reached the standard for medical oral water. The difference in the number of colonies before and after disinfection was statistically significant (P<0.05). Conclusion This self-designed automatic disinfection device can effectively reduce bacterial contamination and provide patients with safe clinical water. It is more convenient, effective and safer than traditional manual disinfection, and is worthy of promotion and application. |
