Why, after reprocessing the instruments in the thermal washer disinfector, did they oxidise or suffer surface discolouration?

Oxidation and/or discolouration phenomena are almost never directly attributable to the activity of the thermal washer disinfector; in most cases they are attributable to interactions between residues of chemical products on the instruments, possibly deriving from the previous decontamination process in a static tank, and the process chemicals of the thermal washer disinfector. In this regard, it is always advisable to rinse the instruments thoroughly before loading them into the thermal washer disinfector.

If I use a thermo washer disinfector to reprocess the instruments, do I risk damaging them and having to replace them more frequently?

Absolutely not. On the contrary, the exact opposite is true. By using an automatic device, such as the thermal washer disinfector, I ensure the best possible cleaning standard for the instruments, validated and not subject to the randomness that derives from the human element represented by the operator, thus optimising the useful life of the instruments themselves.

Can I use accessories such as baskets, supports, etc., from my old thermal washer disinfector?

All manufacturers validate the washing effectiveness of their machines in combination with specially developed accessories. Therefore, neither final success nor validation is guaranteed when using accessories that have not been developed and validated by the manufacturer.

Since I use a sterilizer in my office, why should I also use a thermal washer disinfector?

Thermal washer disinfectors and autoclaves are devices that cannot be missing in a modern workflow, as they perform different but at the same time absolutely complementary tasks. The main objective of a thermal washer disinfector is to clean all dental instruments in a thorough and validated manner, protecting operators from the risk of cross-infections and reducing the pathogenic load thanks to the thermodisinfection process. All these phases are absolutely preparatory in order to ensure that the subsequent sterilization phase can take place in ideal conditions.

  Depending on the load, one or two washing levels can be used with Thed devices. This enables an optimum capacity utilisation of the 64-litre chamber and makes it possible to cope with different workloads during the working week. The W&H devices are therefore unique in their class.
- Automatic rack recognition
  
  Thed+:
