To disinfect instruments is just as relevant as the cleaning and sterilization to ensure cross-contamination can be prevented.
Through the disinfection process the number of pathogens will be reduced to 5 log10- to ensure an infection or pathogen transmission can be eliminated. For the manual disinfection of handpieces chemicals are required, which will be used to flush the handpiece.
Comparison to thermal disinfection
Contrary to the automated disinfection process through a thermal disinfector, these chemicals (Aldehydes based on QAV) have a few downsides - Still MK-dent products are validated to be disinfected with them as long as the instructions for use are applied correctly.
Upside:
- Lower cost of material
Downside:
- Potential gaps in effectiveness.
- Some organisms can show primary bacterial resistance to individual active substances or adaptation can occur. Bacteria are particularly insensitive to disinfectants when they form spores and/or grow in the biofilm.
- The disinfectant itself can be contaminated and trigger an infection.
-
Chemical disinfectants are often dangerous (extremely flammable, caustic, harmful, irritating, and allergenic) and therefore a health risk for staff and patients.
- In general, chemical disinfection is associated with corrosion risks.
Though manual disinfection poses some risks, MK-dent products are validated to be successfully disinfected through this process. Please check the individual instructions for use to confirm.
Process:
a) Required equipment:
- Paper cloth
- ALPRO WL-cid
- Suitable lubrication adapter/cleaning tool
- ALPRO WL-dry
b) Ensure the following steps are executed properly:
1. Surface disinfection
Spray the cloth with a sufficient amount of ALPRO WL-cid and wipe down the entire handpiece.
2. Internal disinfection
Take the lubrication adapter and screw it onto the ALPRO WL-cid spray can. Ensure the adapter is properly seated and the o-ring is in good condition. Push the button on the spray can 1 times for 3 seconds each to properly flush the inside of the handpiece. Remove the handpiece form the adapter and set it down for an exposure time of 2 minutes. Ensure to not over exceed the recommended exposure time

3. Drying
To ensure the disinfectant solutions will not remain inside the handpiece, causing possible corrosion, kindly ensure to properly use the ALPRO WL-dry to dry the handpiece from the inside and outside.
Grab the ALPR WL-dry spray can and attach the lubrication adapter/cleaning tool. Press the button of the spray can until no further liquid is coming form the head.
Drying your equipment after cleaning & disinfection is essential for the lifetime of the equipment. Learn more about the possible consequence by clicking here.
