infection control is
our priority!

Following the current pandemic, we have put all our efforts to build the safest dental treatment environment for you. Infection control procedures are actions taken in The Top Dental Clinic to prevent the spread of disease. We care about your safety and work hard to prevent the spread of infection. That is why we have designated 2 big areas specifically for sterilization and decontamination processes.  A dirty-to-clean workflow is essential in reducing the risk of cross-infection.

We have achieved the ideal separation- we have separate rooms for dirty and clean segregation. Zones are clearly labelled and instrument decontamination takes place as far away from the dental chair as possible. Between the dirty and clean part there is no human interaction. The instruments are placed in the autoclave (MELAG- the highest class of autoclaves and filters in the world) from the dirty zone and removed from the second door of the autoclave located in the clean area by a different person.


Infection prevention is a priority in The Top Dental Clinic where we have developed a protocol of work that is incomparable to any other!

Furthermore, all instruments are labeled and tracked via the LM- tracking system. This means, that at each moment we know what type of instruments are used, where they are used, which dentist is using them and on which patient. All that information is saved to the patient file. Moreover, we know at which point of sterilization they are after being submitted for cleaning.
By employing the LM tracking system , the server knows the status of each article and allows the clinician to automatically double check if expiry dates have lapsed and if instruments have passed the proper reprocessing steps, inspections and validations. The database includes the records for the specified disinfection, maintenance and sterilization procedures and includes the detailed history of every instrument and material. Reducing risks through automatic checks and alerts adds an additional layer of safety without cumbersome manual work.

Instrument cleaning is the process of removing all visible debris from the instrument surface. This takes place through manual cleaning, an ultrasonic bath or a washer-disinfector. At The Top-we use all 3 methods.
During the process of cleaning, personal protective equipment is worn. Instruments are cleaned as soon as possible after use, as this makes the process easier.
Manual cleaning takes place using a long handled brush with instruments immersed in warm water, using a suitable detergent. After cleaning, instruments should be rinsed to remove any trace of detergent.
Prior to ultra-sonic cleaning, instruments are immersed in cold water with detergent. Prior to sterilisation, any instruments that have not been processed via a washer-disinfector are rinsed to remove any trace of detergent and dried with a lint-free cloth.
Washer-disinfectors not only clean instruments but also include a disinfection cycle which allows for the safe handling and inspection of instruments prior to sterilisation. There are five generic stages during the process of a washer-disinfector. These are: flush, wash, rinse, disinfect and dry

  •  ‘Flush – removes “difficult” gross contamination, including blood, tissue debris, bone fragments and other fluid and solid debris.
  • Wash – removes any remaining soil. Mechanical and chemical processes loosen and break up contamination adhering to the instrument surface.
  • Rinse – removes detergent used during the cleaning process.
  • Thermal disinfection – the temperature of the load is raised and held at the pre-set disinfection temperature for the required disinfection holding time.
  •  Drying – Purges the load and chamber with heated air to remove residual moisture.’
    ALL instruments, however cleaned, are inspected for any visible debris.
Disinfection is the process of reducing the number of pathogens to a harmless level.
Sterilisation using steam under pressure is considered the best option for use in the dental environment. This is achieved using an autoclave. Steam pours down on instruments or a vacuum approach means that instruments may be pouched prior to sterilisation.
Items that are either packaged after sterilisation or the items packaged prior to sterilisation remain sealed in packaging. Safe transport from and to the decontamination area is important to avoid potential sharps injuries and incidents.
All aspects of the automated decontamination process are validated. This ensures that equipment is operating at a high level of performance and carrying out the specified task. Any decontamination equipment used is certificated, and tested on a daily basis. Audits of these tests are kept for two years. Records of validation include safety checks, cleaning/sterilisation efficacy, time steam and temperature testing, steam penetration tests, load dryness and automatic control tests.
Hazardous waste or clinical waste is any item that poses a risk to health. This risk extends to the environment outside of the dental practice. For health and safety purposes, appropriate waste segregation and disposal procedures is followed.
This includes the disinfection of dental impressions, dentures, orthodontic appliances, bite raisers and any other prostheses. Prostheses are disinfected using an appropriate disinfectant for the recommended time period according to the manufacturer’s guidelines. This disinfection process occurs before and after any prostheses are placed into or removed from a patient’s mouth.
This term includes management of amalgam/mercury spillages and other clinical spillages such as vomit or urine. Spillage kits are readily available at The top. Details of the management process are readily accessible from the infection control file and the infection control lead will be able to carry out necessary training.

Having a detailed and accessible sharps management procedure readily available is vital after receiving a sharps injury, as it can be a stressful and anxious time. A suitable procedure includes:
• Stopping the activity;
• Removing the glove;
• Encouraging the wound to bleed under running water;
• Drying the wound and applying a waterproof dressing;
• Assessing the risk of contamination;
• If there is contamination, reporting to occupational health for possible further action;
• Whether or not there is contamination, reporting the injury in the accident book.

DUWLS are flushed/purged for at least two minutes at the start and end of the day, and the start and end of any time period where they have not been in use for an extended time (such as lunch breaks). In between patients, lines are flushed for 20 seconds.
If the decontamination process must take place in the treatment room then it should only be carried out when there is no patient present, as aerosol generated will be lessened. A clean-to-dirty airflow is required when designing a surgery or fulfilling infection control guidelines.

Due to the high risk of infection in clinical areas, equipment used to clean the different areas of the clinic is segregated from other equipment and the cleaning process is also isolated. Colour coding assists in control infection.

Each decontamination room has a nominated infection control lead. This role includes ensuring all clinical staff are following the infection control policy, ensuring that staff members receive regular training, and ensuring that all processes and policies are up to date.
Before you enter the examining room, all surfaces, such as the dental chair, dental light, drawer handles and countertops, have been cleaned and disinfected. We cover some equipment with protective covers, which are replaced after each patient. Non-disposable items like the dental tools are cleaned and sterilized between patients. Disposable dental tools and needles are never reused. Our infection control precautions also require all dental staff involved in patient care to use appropriate protective equipment such as gloves, masks, gowns and eyewear when needed. After each patient, disposable gloves and masks are thrown away. Before seeing the next patient, everyone on the treatment team washes their hands and puts on a new pair of gloves. Your well-being is important to us. That’s why we have employed such strict infection control procedures in place. For your 24-hour protection!
