Infection Control

Sterilization and Disinfection of Dental Instruments

Trisa Dental Solutions follows a strict sterilization protocol on daily basis and each patients for non- disposable equipments & instruments.

  • The hygiene of the clinic is maintained thoroughly by a dedicated housekeeping staff.
  • Disposable things like gloves, masks, used cotton, needles & syringes are carefully packed in segregation and color coded disposable bags and discarded.
  • The clinic follows the mandatory sterilization procedures such as Vacuum Autoclaving, Cold Sterilization, Glass Bead and Ultrasonic Cleaner to ensure maximum safety and hygiene.
  • The clinic undertakes all the measures necessary to confirm to the mission of Quality Dental Care and its commitment to society and environment.
  • Each set of gloves & masks are used only once for one patient. Both the assistants and dentists maintain the hand wash protocol before & after treating the patient to prevent any cross contamination & infection.

Steps for Sterilizing Instruments & Equipments :-

  1. Manual Cleaning with clinical spirit.
  2. Immersing in a solution of disinfectant.
  3. Packing in sterilization pouches and autoclaving.
  4. Storing in UV chamber until required and opened in front of the patient.

ISO Certified Sterilization Protocol Followed :-

  1. Critical instruments used to penetrate soft tissue or bone, or enter into or contact the bloodstream or other normally sterile tissue Are sterilized after each use. Sterilization is achieved by steam under pressure (autoclaving). Critical instruments include forceps, scalpels, bone chisels, scalers and surgical burs.

  2. Semi-critical instruments are those that do not penetrate soft tissues or bone but contact mucous membranes or non-intact skin, such as mirrors, reusable impression trays and amalgam condensers. These devices are sterilized after each use. In some cases, however, sterilization is not feasible and, therefore, high-level disinfection is appropriate.

  3. Non-critical instruments are those that come into contact only with intact skin such as external components of x-ray heads, blood pressure cuffs and pulse oximeters. Such devices have a relatively low risk of transmitting infection; and, therefore, may be reprocessed between patients by intermediate-level or low-level techniques Such as mechanical cleaning (e.g., ultrasonic cleaners) are used to reduce direct handling of contaminated instruments. We apply rust inhibitors to protect instruments from corrosion that may result from autoclaving. Packaging rinsed and dried instruments before sterilization protects them from contamination after they are removed from the sterilizer.

Why Trisa Dental Solutions Is The Safest Place For Dental Surgery?

Sterilization is done for all high-speed dental handpieces, low-speed handpiece components used intraorally and reusable prophylaxis angles. We strictly follow the manufacturers instructions for cleaning, lubrication and sterilization procedures to ensure the effectiveness of the sterilization process and the longevity of these instruments. High-speed and low-speed handpieces produced today are heat tolerant.

  1. Biological Indicators :- Proper functioning of sterilization cycles are verified by periodic use of spore tests called biologic indicators. Biologic indicators consist of highly resistant bacterial spores of Bacillus (Geobacillus) stearothermophilus (used to monitor steam and unsaturated chemical vapor sterilizers) or Bacillus subtilis (used for monitoring the dry heat sterilizer). The CDC recommends that all sterilized implantable devices be quarantined until the results of biological monitoring are known.

  2. Chemical Indicators :- Chemical indicators (in the form of tape, strips, tabs and special markings on packaging material) indicate exposure to heat. Heat-sensitive chemical indicators that change color after exposure to heat do not guarantee sterilization and are placed inside each pack, and on the outside of each pack when the internal indicator is not visible from the outside, to identify packs that have been processed through the heating cycle. Chemical indicators are placed in the center of a load of unwrapped instruments.

  3. Flash Sterilization :- Flash sterilization is a method for sterilizing unwrapped instruments for immediate use. This cycle operates at a higher temperature for a shorter period of time than the normal sterilization cycle. The CDC* recommends that flash sterilization not be used routinely in the dental office to sterilize patient instruments this process should only be used in unavoidable situations.

  4. Cold Sterilization :- In all dental and other health-care settings, indications for the use of liquid chemical germicides to sterilize instruments (i.e., "cold sterilization") are limited. For heat-sensitive instruments, this procedure may require up to 10 hours of exposure to a liquid chemical agent registered with the EPA as a sterilant/disinfectant." Instruments sterilized in this manner are rinsed with sterile water, dried and placed in a sterile container (if not used immediately).
