The Importance of Dental Chair Pipeline Disinfection

In oral healthcare, chlorine in tap water is removed during the filtration process, which eliminates its antibacterial properties and leads to the formation of biofilm. Biofilm can detach from the inner walls of pipes at irregular intervals, flow through the pipes, and pose a risk of infection to the human body. It can also cause blockages in medical equipment pipelines.

Moreover, the use of the same water supply system for three-way syringes, mobile phone drills, and other dental instruments can easily contaminate the dental chair's water supply system because dental phone drills have suction function. Even if the mobile phone drill is clean, cross-infection cannot be avoided when contaminated water is used for ultrasonic teeth cleaning. To ensure the dental experience of patients and their safety, as well as protect the health of dental doctors and nurses, the dental chair's spit pipe needs to be disinfected before and after treatment. Disinfecting the spit pipe is also crucial to protect the health of dental doctors and nurses.

Disinfection of dental chair pupeline between patient visits

The pipeline should be disinfected between each patient's treatment to prevent cross-infection and take responsibility for the patient's health. Depending on the degree of contamination, there are mildly contaminated customers and heavily contaminated customers, and the disinfection methods are different. For mildly contaminated customers, dental staff need to rinse the spittoon with clean water during the patient's visit. After cleaning, it is also essential to suck one cup of clean water with a suction device.

If the customer is heavily contaminated, when encountering heavy contamination, in addition to sucking clean water, at least one liter of 500mg/l chlorine-containing disinfectant should be sucked back. A bucket of 500mg/l chlorine-containing disinfectant can be prepared in advance every morning.

Disinfection of dental chair after daily consultation

After each day's treatment, the spit pipe of the dental chair spares needs to be disinfected. If the dentist's suction tube is severely blocked, the suction force of the dental chair will decrease, affecting the progress and completion of dental work.

The first step is to ensure the smooth flow of water. The dental chair needs to be raised, and the internal circuit of dental chair spares should be pulled out before proceeding with the next step.

The second step is to rinse the pipeline with a pre-prepared multi-enzyme solution, using approximately 1000ml of the solution, for 10-15 minutes at a temperature of 20~25℃. This facilitates the function of the multi-enzyme solution and solves the problem of a blocked pipe in the dental chair.
