Sterilization

Your safety is a major priority for us and we strictly adhere to our high standards of sterilization and hygiene. Professional and meticulous, we follow and exceed current International dental guidelines and are rigorous in regularly maintaining our sophisticated equipment. The process of sterilisation in the Cosmodentz clinics is constantly subjected to control and monitoring, both internally and externally. Each and every step is taken to save you from cross infection.

We use the most advanced methods of sterilization and disinfection available for your safety and the protection of your health.

We meet or exceed all guidelines of professional organizations and government regulations.

Some of the techniques routinely used include:

 • Extensive use of disposable supplies, used once and discarded. Gloves, masks and needles are all disposable.
 • Meticulous cleaning of all instruments prior to sterilization in an ultrasonic machine, followed by inspection and additional cleansing of each instrument by hand prior to sterilization.
 • Sterilization of all instruments, including dental hand pieces in computer monitored autoclaves.
 • Routine maintenance of all instruments and equipment as recommended by manufacturers.
 • Sterilization of non-disposable plastic instruments by immersion in hospital grade sterilizing fluid for 15 hours. (exceeding the methods used in hospitals for surgical instruments and laproscopes).

At Cosmodentz Dental , we use Class B (Gold Standard Autoclave in Dentistry) and Class N autoclaves. The sterilizer carries the CE mark and complies with British Standards (BS EN 13060).

The decontamination of reusable dental instruments includes:

 • Cleaning
 • Thermal disinfection in a washer-disinfector
 • Chemical disinfection
 • Ultrasonic Cleaning
 • Manual washing and inspection
 • Rinsing
 • Drying
 • Inspection for dryness, functionality and cleanliness
 • Wrapping before sterilization using a vacuum sterilizer
 • Sterilization with Class B fully automatic autoclave
 • Storage

Sterilization and Disinfection of Dental Instruments According to the Centers for Disease Control (CDC), dental instruments are classified into three categories depending on the risk of transmitting infection. The classifications of critical, semicritical and noncritical are based on the following criteria:

1) Critical instruments are those used to penetrate soft tissue or bone, or enter into or contact the bloodstream or other normally sterile tissue. They must be sterilized after each use. Sterilization is achieved by steam under pressure (autoclaving), dry heat, or heat/chemical vapor. 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 also should be sterilized after each use. In some cases, however, sterilization is not feasible and, therefore, high-level disinfection is appropriate. A high-level disinfectant is registered with the U.S. Environmental Protection Agency (EPA) as a "sterilant/disinfectant" and must be labeled as such.

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 disinfection. An intermediate-level disinfectant is EPA-registered as a "hospital disinfectant" and will be labeled for "tuberculocidal" activity (e.g., phenolics, iodophors, and chlorine-containing compounds). A low-level disinfectant is EPAregistered as a "hospital disinfectant" but is not labeled for "tuberculocidal" activity (e.g., quaternary ammonium compounds). The tuberculocidal claim is used as a benchmark to measure germicidal potency. Germicides labeled as "hospital disinfectant" without a tuberculocidal claim pass potency tests for activity against three representative microorganisms: Pseudomonas aeruginosa, Staphylococcus aureus, and Salmonella choleraesuis.
