Effective cleaning of dental tools is essential and necessary for disinfection and sterilization of the devices to avoid the danger of transmitting infections from one patient to another. Any organic material or dental material that is not properly cleaned remains on the dental tools and contaminates them.
There are many dental tools that need to be cleaned very carefully, and it is not possible to clean them manually. Manual cleaning is not thorough at all and may even endanger the assistant who cleans the dishes, with infections.
The cleaning devices that must be in every dental clinic, are mostly ultrasonic cleaners and autoclaves. How do these devices work and why is it important to clean the dental tools using them? Let's check.
How do the cleaning devices in the dental clinic work?
The cleaning devices in the dental clinic clean with intensity and high heat to remove residues of hazardous substances from the dental utensils. Do not clean the devices with manual cleaning. But only in mechanical cleaning with high cleaning power. This is because staff members who work with non-sterilized and disinfected equipment are at risk. They may be exposed to bacteria and other infections.
What is special about the cleaning devices - Autoclave and Ultrasonic Cleaner
The mechanical cleaners clean the dental tools with a thorough cleaning. Autoclaves sterilize steam power contaminants. These are devices that clean the dental tools in a vacuum and very quickly. At the end of the cleaning process the autoclaves dry the devices and tools well.
The ultrasonic cleaner is actually an industrial means of cleaning and disinfection. With extremely strong cleaning power that operates on a unique heating system. It can be easily cleaned with metal, plastic or ceramic utensils. Its heat intensity is sufficient for cleaning hard dirt, solutions of hazardous chemicals and even organic tissues.
What types of tools in dental clinics are cleaned using an ultrasonic bath and autoclave?
Ultrasonic Bath (Cleaning Stage)
The ultrasonic bath uses high-frequency sound waves in a cleaning solution to remove debris, blood, saliva, and other contaminants from instruments before sterilization.
Instruments typically cleaned in an ultrasonic bath:
- Hand instruments: scalers, forceps, elevators, curettes
- Dental mirrors
- Explorers and probes
- Endodontic files and reamers
- Impression trays (metal ones, not plastic)
- Burs and polishers (metal and carbide types)
- Ortho tools: brackets, pliers (if compatible)
Note: Plastic or delicate instruments may not be suitable depending on the solution and frequency.
Autoclave (Sterilization Stage)
The autoclave uses high-pressure saturated steam (usually at 121–134°C) to sterilize instruments that have already been cleaned.
Instruments typically sterilized in an autoclave:
- All metal instruments: including those listed above
- Surgical tools: forceps, needle holders, scalpel handles
- Handpieces: if marked as autoclavable
- Burs: steel, carbide, and diamond (check compatibility)
- Endodontic tools
- Orthodontic pliers
- Implantology instruments
Not suitable for autoclave:
- Heat-sensitive items (plastic trays, some handpiece components, impression materials)
- Items labeled "single-use only"
What happens if the dental tools are not disinfected?
If the dentist uses non-disinfectable dental tools in cleaning devices, patients may develop diseases as a result of the infection being transmitted to them. The dentist must be aware of the importance of disinfecting the dental tools he uses and make sure that his staff cleans them with the appropriate cleaning tools.
Cleaning is a necessary condition for the prosperity of the dental clinic
It is extremely important to keep the various dental tools clean to prevent the transmission of infections from one patient to another and from one patient to the dentist and the clinic staff who assist him. Sterilization - is the only process that kills all forms of bacteria, fungi and viruses. Strict disinfection procedures require the dentist and clinic staff to clean the dental tools before and after each treatment thus maintaining the health of the patients. The cleaning requirements of the Ministry of Health and the strict quality standards that accompany the manufacturing processes of the cleaning devices, are necessary conditions for the success of any dental treatment and the prosperity of the clinic. And for that, quality dental equipment should be used
