Why take the risk?

For decades, the biggest change to air water syringes was adding a single-use air water syringe tip. Current cleaning methods for the air water syringe is covering your dental syringes in plastic and a quck wipe down with high-level disinfectants. Unfortunately, air water syringes are never heat-sterilized. Why? The design is outdated. The air water syringe system is the most used item in the dental practice. Should a patient feel comfortable with a device that is used on every patient and has never been heat-sterilized? Would you?

Public trust in dental health

What if patients were informed of the dangers presented by this high-use, semi-critical dental device? Most air/water syringe systems do not comply with CDC, ADA, FDA, or OSAP recommended device sterilization standards in today's dental office. There are many globally documented cases of cross-infection involving dental offices. These occurrences had enormous impact on patient lives, dental practices, and the communities where they occurred.

Dental Infection Control Updates

First case of patient-to-patient transmission

Dr. Scott Harrington's office in Oklahoma is the source of the first case of patient-to-patient transmission of hepatitis C in a clinical setting. Due to the lack of proper infection control protocols, over 7,000 patients were informed to seek medical blood testing to test for HIV, hepatitis B and C. Of the patients tested, 89 tested positive for hepatitis C, 5 for hepatitis B, and 4 for HIV.

Patients at risk of infection

Five former patients of HIV-scare dentist Desmond D'Mello test positive for hepatitis C. More than 22,000 patients were called in for testing after dentist was found to be violating multiple infection control protocols. Investigations began after a young woman died weeks after being treated by Dr. Desmond D'Mello.

Mr D’Mello is being investigated by the Care Quality Commission and the General Dental Council and is no longer practicing. The father-of-four was secretly filmed by a whistleblower failing to change his medical gloves between patients or properly sterilise equipment.

Dental infection outbreak at Anaheim clinic

Pediatric dental infections contracted at an Anaheim clinic increased to 22 on Tuesday, as Children's Dental Group said most of the 500 children who underwent root canals there have been examined for signs of illness. Among the 22 patients, ages 3 to 9, six remain hospitalized.

CDC UPDATE 2018

CDC guidelines for infection prevention and control state that, between patients, dental health care personnel (DHCP) should clean and heat-sterilize handpieces and other intra-oral instruments that can be removed from the air and waterlines of dental units.

If a dental handpiece cannot be heat sterilized and does not have FDA clearance with validated instructions for reprocessing, do not use that device.
September 2018
Unsanitary sterilization practices

The Galveston County Health Department revealed an audit of CHWC's dental offices found unsanitary sterilization practices for the past three years and might have led about 9,500 former patients to have contracted hepatitis B, hepatitis C, and/or HIV.
September 2018
Two high-profile safety breaches

Two high-profile safety breaches have highlighted the importance of close adherence to infection control protocols in dental clinics and offices. In both recent cases, patients have been advised to undergo testing for HIV and hepatitis B and C due to possible exposure to bloodborne pathogens.

In Seattle, and nearby Vashon Island, news broke in early April that nearly 1,300 students face infection risks because equuipment used in school clinics was improperly sterilized. Ten school-based dental clinics operated by Neighborcare, a local health center, have been impacted by the safety breach.

COVID-19

COVID-19, an airborne virus, creates a world-wide pandemic and effectively shuts down the world for months. Dental offices are closed to prevent the spread of the disease.
September 2020
Present Day

What has your office done to prepare for the next infection control disaster? Are we using best practice recommended by leading authorities or governing bodies? Are we being proactive or reactive?

Infection control breaches will happen. How we prepare and mitigate risk, liabilities and improve patient safety is only a decision that can be made by you. DCHP, do you believe that an item used on every patient, for every procedure and is never sterilized is not a story waiting to happen?

Definition

Semi-Critical Device: Instruments such as mirrors and amalgam condensers that do not penetrate soft tissues or bone but contact oral tissues are classified as semi-critical.

Recommendations

Guidelines provided by local and government level agencies to help ensure the dental office is safe for its dental health care providers and patients.

USA
Recommendations

FDA

This is to notify you that the Food and Drug Administration (FDA) recommends that reusable dental handpieces and related instruments (such as air/water syringes and ultrasonic scalers) be heat sterilized between each patient use. Since 1989 CDC has recommended that those dental handpieces that cannot b e autoclaved only be used until the practitioner can replace them with a handpiece that can be autoclaved.
See Full Recommendation
CDC

Other resusable intraoral instruments attached to, but removable from, the dental unit air or water lines - such as ultrasonic scaler tips and component parts and air/water syringe tips - should be cleaned and sterilized after treatment of each patient in the same manner as handpieces.
See Full Recommendation
CDC

“Because the majority of semi critical items in dentistry are heat tolerant, they should be sterilized using heat. If a semi critical item is heat-sensitive, the DHCP should replace it with a heat-tolerant or disposable alternative. Therefore, handpieces and other intraoral instruments should be removed from the air and water lines of dental units, cleaned, and heat-sterilized between patients..."
See Full Recommendation
CDC

The CDC's 2003 Guidelines for Infection Control in Dental Healthcare Settings recommend that all components of handpieces that can be removed from the air and waterlines should be cleaned and then heat sterilized. Therefore, handpieces and other intraoral instruments should be removed from the air and waterlines of dental units, cleaned, and heat-sterilized between patients.
See Full Recommendation
ADA

In April, 2018, the CDC released a Statement on Reprocessing Dental Handpicks stressing that handpieces (both low-speed and high-speed) and other intraoral instruments that can be removed from the air lines and water lines need to be heat sterilized between patients and that reusable devices made prior to 2015 may not meet current FDA reprocessing guidance.
See Full Recommendation
OSAP

In keeping with the CDC, ADA, and OSAP recommendations, your dentist should be heat-sterilizing all instruments that penetrate or contact a patient's oral tissues.Your dentist should heat-sterilize instruments that have been used on a patient before they are introduced to treat the next patient.
See Full Recommendation
Joint Commission

Health care organizations and providers that use dental handpieces should be aware that studies have demonstrated how internal components of air-driven low- and high-speed dental handpieces may become contaminated with patient material during use, and that retained patient material may then be expelled intraorally during subsequent uses.

Royal College of Dental Surgeons of Ontario

All critical and semi-critical instruments used in dentistry, including handpieces, are available in heat-tolerant and/or single-use (disposable) forms. All heat-tolerant resuable critical and semi-critical instruments must be heat-sterilized between uses.
See Full Recommendation
Provincial Dental Board of Nova Scotia

Semi-critical patient care items must be sterilized or considered as single-use items. The use of high-level disinfectants is not an appropriate sterilization method.
See Full Recommendation
Royal College of Dental Surgeons of Ontario

Several dental devices that contact mucous membranes are attached to the air or waterlines of the dental unit. These devices have the potential of retracting oral fluids into their internal compartments, which can then be expelled into the oral cavity of another patient during subsequent use.

Australia
Recommendations

Australian Dental Association:

Semi-Critical items, where there is contact with intact non-sterile mucosa or non-intact skin. Instruments must be sterilized between patients where possible. When not possible, use thermal disinfection or instrument-level disinfection. Instruments should be 'single-use disposable' or sterilised after use.

Time to upgrade

The same air/water syringes that have been used for over 30 years are still being used today. The CDC, ADA, FDA and OSAP all recommend that this semi critical device should be removed between patients to be heat-sterilized. The problem is, once installed, current air/water syringes are never removed to be heat-sterilized. This makes the air/water syringe non-compliant with leading health authorities.
