Why is the dental chair waterway always not clean？
Due to in the daily operation of the dental clinic. The dental integrated treatment table water system (DUWLs) can be regarded as a “black box”. At the same time it consists of narrow silicone tubes several meters long. Complex solenoid valves and multiple interfaces, and the water flow is in a low flow rate and static state for a long time.
Traditional disinfection methods often face three embarrassments:
- Apparently clean, but actually exceeded the standard: ordinary water washing can only take away the plankton, but can not shake the biofilm on the tube wall.
- Chemical residue and corrosion: chlorine-containing disinfectants (such as 84) are effective but irritating. And long-term use will corrod the internal metal parts of the pipeline and leave a pungent odor.
- Intermittent disinfection, ineffective rebound: disinfection once a week, biofilm in the disinfection interval period of rapid regeneration. Resulting in water quality “today qualified, tomorrow exceeded the standard”.

Solution: Hypochlorous acid generator deep cleaning dental chair pipeline
Due to hypochlorous acid generator through on-site electrolysis technology, instant generation of high purity, low concentration of slightly acidic hypochlorous acid water. Therefore it is not a simple dilution of disinfectant, but a “targeted cleaning disinfectant” for the characteristics of dental chair waterways.
1. Disintegrate biofilm: Make the line really clean
At the same time biofilms are a matrix of sticky polysaccharides secreted by bacteria, like a stubborn layer of limescale. Conventional disinfectants are difficult to penetrate.
Mechanism of action: hypochlorous acid molecules without charge, small volume, strong penetration. It can easily penetrate the protective layer of the biofilm, oxidize and decompose the bacterial cell wall from the inside, and make the biofilm peel off from the tube wall and exit with it.
Lorem ipsum dolor sit amet...
The hypochlorous acid generator supports continuous perfusion mode due to the highly rebound nature of the dental chair waterway.
- Low concentration maintenance: use 10-20mg/L low concentration hypochlorous acid water instead of tap water as the dental chair water source.
- While washing and eliminating: in the interval of patient diagnosis and treatment, the water continues to wash the pipeline, so that bacteria and organic residues have no place to attach, and realize the integrated process of “disinfection liquid is flushing liquid”.
3. Green without residue: end corrosion and odor problems
When water hypochlorous acid comes into contact with organic matter, it quickly decomposes into normal water and releases trace amounts of oxygen.
- No chemical residue: no need for additional flushing and dechlorination, avoiding the stimulation of traditional disinfectant residues on the patient’s oral mucosa.
- Friendly material: the slightly acidic (pH 5.0-6.5) environment is consistent with the human body environment, and the corrosion of the sealing ring and metal joint inside the dental chair is very low, which prolongs the life of the equipment.
How to use good hypochlorous acid generator for cleaning and disinfection?
To get the most out of it, a three-step strategy is recommend:
1，Initial impact (pipeline dredging period) :
At the same time use high concentration (40-50mg/L) hypochlorous acid water to soak and high-pressure rinse the whole pipeline system for 1-2 hours. The purpose of this step is to completely remove the thick biofilm residue that has accumulated in the old pipe for many years.
2，Daily maintenance (dynamic cleaning period) :
The output concentration of the generator was adjust to the daily maintenance mode (10-20mg/L) and directly connected to the dental chair water supply system. Make sure that every time you turn your phone, every mouthful of mouthwash, it is sterilize “living water”.
3，Night maintenance (deep bacteriostatic period) :
After the daily treatment, shut off the water source and keep the pipe filled with hypochlorous acid water for overnight. The residence time at night was use to carry out continuous antibacterial penetration on the inside of the pipeline to prevent biofilm from growing at night.
FAQ
Hypochlorous acid is used for oral disinfection, how much concentration is appropriate?
A number of studies have confirmed that slightly acidic hypochlorous acid water with effective chlorine concentration of 10 mg/L can achieve ideal disinfection effect when used for continuous disinfection of dental chair waterways. A study involving 50 comprehensive dental treatment units showed that after continuous disinfection with 10 mg/L non-electrolytic slightly acidic hypochlorous acid solution, the pass rate of bacteria detection of high-speed mobile phone water, three-use gun water and mouthwash reached 100%, which was significantly higher than that of traditional manual disinfection method (43.8%).
