Highlights
With the improvement of people’s living standards and the enhancement of oral health awareness, oral health has been paid more and more attention
Considering the balance between disinfection effectiveness and the damage rate of the dental unit component, we proposed a preventive strategy
After the dental unit pipes are disinfected, the failure rate of water valves are significantly reduced, and water valves replacement costs are saved through the installation of automatic discharge water control device and the implementation of relevant measures
Summary
With the improvement of people’s living standards and the enhancement of oral health awareness, oral health has been paid more and more attention. The dental clinic of most domestic hospitals is often overcrowded, and the number of patients treated every day is much higher than in some foreign hospitals.
