What should be paid attention to during the disinfection and cleaning of the Dental Dental Instruments Kit?

Dental Dental Instruments Kit is an indispensable tool in oral diagnosis and treatment. Because it is in direct contact with the patient's mouth, it needs to be strictly cleaned and disinfected to ensure the safety of patients and medical staff. The correct cleaning and disinfection process can not only extend the service life of the instrument, but also effectively prevent cross infection. The following details the key points of the dental instrument kit in the disinfection and cleaning process from four aspects: cleaning, disinfection, storage and precautions.

1. Cleaning process
Cleaning is the basic link of disinfection, and the purpose is to remove blood, saliva and other contaminants on the surface of the instrument.

Preliminary rinse

After using the instrument, rinse the surface with running water immediately to prevent blood stains or saliva from drying up.
Be careful to avoid high-pressure water flow to avoid splashing contaminants and causing secondary contamination.
Immersion cleaning

Use a special instrument cleaning solution or neutral detergent to soak the instrument for about 10-15 minutes.
Avoid using acidic or alkaline detergents to avoid damaging the surface material of the instrument.
Scrubbing details

Use a soft-bristled brush to manually clean the complex parts of the instrument (such as the tip of the tooth and the joint) to ensure that the dirt is completely removed.
Wear medical gloves when scrubbing to prevent the instrument from damaging the operator's hands.
Thorough rinsing

Rinse the instrument with deionized water or purified water to prevent detergent residue from affecting the subsequent disinfection effect.
2. Disinfection process
The cleaned instrument needs to be disinfected efficiently to kill potential pathogens.

High temperature and high pressure sterilization

High temperature and high pressure sterilization is the preferred method for disinfecting dental instruments. The cleaned instruments are placed in a sterilization bag and placed in an autoclave.
Common parameters are 121°C (15 minutes) or 134°C (3-5 minutes).
Chemical disinfection

For instruments that are not resistant to high temperatures (such as lenses or some plastic parts), chemical disinfectants can be used for immersion disinfection.
The immersion time and concentration should be strictly in accordance with the instructions for use of the disinfectant to avoid damage to the instrument due to excessive immersion.
Ultrasonic cleaning and disinfection

Ultrasonic cleaning combined with disinfectant can further remove tiny residues that are invisible to the naked eye and kill microorganisms at the same time.
This method is suitable for precision instruments with complex structures or difficult to clean.
3. Storage requirements
The dental instrument set needs to be properly stored after disinfection to prevent re-contamination.

Sterile storage

The sterilized instruments should be sealed in sterilization bags and stored in a sterile environment.
Regularly check the integrity of the sterilization bags to avoid loss of sterility of the instruments due to damage.
Classification storage

According to the use of the instruments (such as probes, pliers, etc.), they are classified and stored to facilitate quick access during diagnosis and treatment.
The storage environment should be kept dry and ventilated to avoid moisture causing rust or deterioration of the instruments.
4. Precautions
Material identification

Instruments of different materials (such as stainless steel and chrome-plated alloys) have different tolerances to cleaning agents and disinfection methods, and appropriate treatment methods need to be selected according to the material.
Operation specifications

When using an autoclave, do not stack the instruments to avoid poor steam flow affecting the sterilization effect.
Wear protective equipment during disinfection to avoid direct contact with contaminants or disinfectants.
Check the status of instruments regularly

Check the wear of dental instruments regularly and replace rusty, damaged or non-functional instruments in time.
Recording and tracing

The processing time, method and results of the instruments should be recorded after each disinfection to ensure that the disinfection process is traceable and convenient for quality control.
