Introduction - Basic Expectations for Infection Control
This series gives you an overview of the basic principles of infection prevention and control for dental healthcare practices. It can be used to educate and train infection prevention coordinators, educators, consultants, and other dental healthcare personnel (DHCP.)
During dental treatments, patients and dental healthcare personnel can be exposed to a variety of pathogens or disease-causing organisms. To help prevent transmission of infectious organisms, following recommended infection prevention procedures is not only highly recommended — but ofter required practices.
1. Hand Hygiene
Why is hand hygiene so important? First, hands are the most common mode of pathogen transmission. Hand hygiene can reduce the spread of antimicrobial resistance in health care settings and the likelihood of healthcare-associated infections.
For things like examinations and nonsurgical procedures, use alcohol-based hand rub or either plain or antimicrobial soap and water. If hands are really dirty, opt for antimicrobial soap and water over alcohol-based hand rub.
Surgical hand hygiene can be performed by using either an antimicrobial soap OR an alcohol-based hand rub with persistent activity. When an antimicrobial soap is used, the hands and forearms should be scrubbed for the length of time recommended by the product’s manufacturer. When an alcohol-based hand rub with persistent activity is used, follow the manufacturer’s instructions on the amount of product to use. Prewash hands and forearms with a non-antimicrobial soap and allow them to dry completely. After applying the alcohol-based product as recommended, allow hands and forearms to dry thoroughly before putting on sterile gloves.
2. Personal Protective Equipment
Personal protective equipment (PPE) is a major component of standard precautions for DHCP. Rotary dental and surgical instruments, such as handpieces, ultrasonic scalers, and air-water syringes create a visible spray that contains primarily large-particle droplets of water, saliva, blood, and microorganisms.
In addition to wearing PPE, you should also use safe work practices. Avoid contaminating yourself by keeping your hands away from your face and not touching or adjusting PPE. Also, change your gloves if they become torn, and perform hand hygiene before putting on a new pair of gloves. Avoid spreading contamination by limiting surfaces and items touched with contaminated gloves. All protective clothing should be removed before leaving the work area—such as patient care, instrument processing, and dental laboratory areas.
3. Respiratory Hygiene and Cough Etiquette
The following measures to contain respiratory secretions are recommended for all individuals with
signs and symptoms of a respiratory infection:
Dental office staff can also offer masks to coughing patients and other symptomatic people when they enter the dental setting and encourage people with symptoms to sit as far away from others as possible.
The following supplies should be provided:
Masks may be used to contain respiratory secretions for coughing patients
4. Sharps Safety
The recommended work practices that help ensure safety can be simplified into three quick points:
• Be prepared.
• Be aware.
• Dispose with care.
Before beginning a procedure that involves the use of a needle or other sharps device, DHCP should:
During a procedure that involves the use of needles and other sharps devices you should:
During cleanup following a procedure, DHCP should:
5. Safe Injection Practices
The CDC recommends the following safe injection practices:
6. Sterilization and Disinfection
Patient-care items—such as dental instruments, devices, and equipment—are categorized as critical, semicritical, or noncritical.
Cleaning is the basic first step in all decontamination processes to remove debris and organic contamination from instruments. If blood, saliva, and other contamination is not removed, these materials can shield microorganisms and compromise the disinfection or sterilization process. Automated cleaning equipment (such as ultrasonic cleaners and washer-disinfectors) should be used to remove debris to improve cleaning effectiveness and decrease worker exposure to blood. The majority of patient-care items in dentistry are heat-tolerant and therefore should be heat sterilized.
After cleaning, instruments should be inspected, wrapped, packaged, or placed into container systems before heat sterilization. Instruments should be thoroughly dry before they are packaged, wrapped, or otherwise contained. DHCP should follow the manufacturer’s instructions for the packaging of patient-care items.
7. Environmental Infection Prevention and Control
In the dental operatory, environmental surfaces — for example, a surface or equipment that does not contact patients directly — can become contaminated through touch, splash, or droplets generated during patient care. Certain surfaces, especially ones touched frequently—such as light handles, unit switches, and drawer knobs—can serve as reservoirs of microbial contamination.
There are two categories of environmental surfaces:
Clinical contact surfaces have a high potential for direct contamination from patient materials either by direct spray or spatter generated during dental procedures or by contact with gloved hands of DHCP.
Housekeeping surfaces do not come into contact with patients or devices used in dental procedures. Therefore, they have a limited risk of disease transmission and can be decontaminated with less rigorous methods than those used on dental patient-care items and clinical contact surfaces.
Clinical contact surfaces should be barrier protected or cleaned and disinfected
between patients. Surface barriers are particularly useful for surfaces that are hard to clean, such as switches on dental chairs.
Housekeeping surfaces, carry less risk of disease transmission than clinical contact
surfaces and can be cleaned with soap and water or cleaned and disinfected if visibly contaminated with
blood. Reusable mops and cloths should be cleaned after use and allowed to dry before reuse.
8. Dental Unit Water Quality
Studies have demonstrated that dental unit waterlines— narrow-bore plastic tubing that carries water to the highspeed handpiece, air or water syringe, and ultrasonic scaler—can become colonized with microorganisms, including bacteria, fungi, and protozoa. Once formed, a biofilm serves as a reservoir that may dramatically increase the number of free-floating microorganisms in water used for dental treatment.
Although most organisms isolated from water systems are harmless, some have been known to cause serious disease. Using water of uncertain microbiological quality is inconsistent with infection prevention and control principles. Removal or inactivation of dental waterline biofilms requires the use of chemical germicides.
The CDC recommends that water used for routine dental treatment meet regulatory standards for drinking water, which is fewer than 500 CFU/mL of heterotrophic water bacteria. DHCP should consult with the dental unit manufacturer for appropriate methods and equipment to maintain the recommended quality of dental water and follow recommendations for monitoring water quality provided by the manufacturer of the unit or waterline treatment product.
Commercial devices and procedures designed to improve the quality of water used in dental treatment are widely available. Examples of effective water treatment methods include:
DHCP should always consult with the dental unit manufacturer for appropriate methods to maintain the recommended dental unit water quality.
