WOULD YOU WANT THIS IN
Metal air water syringe tips are anodized on the outside, but the inside is raw metal, that begins corroding from the first use. As they continue to corrode over time, fissures develop, which are perfect pockets to collect biofilm, blood, tissue and materials debris.
These elements are virtually impossible to remove from the micro lumen, and continue to collect over time and usage. The collection of such debris prevents steam condensation on the inner walls of the lumen, thus impeding sterilization in the autoclave.
THE REFLUX EFFECT
Reflux (also known as aspiration or "suck-back") is the normal action that occurs when the dental water button on your air water syringe is released and contaminated aerosol from the oral cavity is retracted into the air water syringe tip due to negative dental water pressure.
THE ULTRASONIC EFFECT
Placing metal air water syringe tips inside an ultrasonic solution, introduces more biofilm inside the lumen through the vibration action. The more the solution is used during the day, the more biofilm develops in the solution.
THE AUTOCLAVE EFFECT
When metal air water syringe tips are placed inside the autoclave, the debris collected inside the lumen from suck-back, spray-back and the Ultrasonic solution, is literally baked into the fissures, or cavities. This clogs the air water syringe tip and the debris can be blown into another patient’s mouth.
FIRST PATIENT-TO-PATIENT HEPATITIS
In 2013 an investigation into an Oklahoma dental practice confirmed a case of patient-to-patient hepatitis C transmission. 89 of this offices' dental patients tested positive for hepatitis C, but only one case was directly tied to this dental practice. Four cases of HIV were also found in his patients; the CDC is conducting genetic testing to determine whether those cases are tied to dental office.
"This is the first documented report of patient-to-patient transmission of hepatitis C virus associated with a dental setting in the United States, state epidemiologist Dr. Kristy Bradley said. "While dental procedures are generally safe, this reinforces the importance of adhering to strict infection control procedures in dental settings."
THE DENTAL ADVISOR TESTS RESULTS,
The persistent presence of organic and inorganic deposits in the lumens (of air water syringe tips) could delay or even prevent penetration of sterilizing vapors.
A number of reports have demonstrated the presence of accumulated deposits in metal air water syringe tips that have been reprocessed many times between patient uses. In some instances, the items were cultured and found to be sterile after autoclaving, while other studies demonstrated inconsistent sterilization outcomes.
The Dental Advisor conducted its own tests in their Biomaterials Research Center and found microbial contamination in approximately 10% of the metal air water syringe tips tested, and concluded:
A general infection control principle states that sterilization of reusable devices requires pre-cleaning. In the particular instance of air water syringe tips, the small lumen openings preclude visual examination of accumulated contaminants on the rough internal surfaces.
Failure to detect the presence of accumulated debris and the inability to clean the lumens therefore provides strong support for the routine use of disposable air water syringe tips.”

IF YOU CAN'T CLEAN IT, YOU CAN'T
The Dental Advisor Report only confirms results from other testing labs, dating to 1994, in which a university study proved that it is virtually impossible to clean the interior surfaces of a metal air water syringe tip, required for sterilizaiton. Or, as another expert concluded in agreement with American Dental Association infection control protocols:
"If you can’t clean it, you can’t sterilize it.” He then added: “The disposable plastic air water syringe tip is the surest way to avoid cross-contamination from patient to patient."
A 2009 article in a leading European dental publication echoed these findings and cited the British Dental Associations 2003 recommendation to use disposables whenever possible.
From a 1997 OSAP report: "The bacteria that enter the tubing are able to adhere to the lining of the tubing and then multiply. Bacteria are continuously released from the surface of the biofilm into the flowing dental water in the line. Patients and clinical staff are then exposed to these planktonic micro-organisms."
According to a 1999 study by Dr. Raghunath Puttaiah of Baylor University, a leading expert in infection control in dentistry, ultrasonic cleaning does not remove all bioburden from within the lumen of metal air water syringe tips. And, although these tips meet sterilization standards, accumulation of internal bioburden over time can compromise sterilization procedures.
In addition to numerous other reports that agree with these findings, Dr. Martin Fulford, BDS, DgDP, FibMS summarized the situation as follows: "The inability to pre-clean the inside of traditional metal air water syringe tips, coupled with the unpredictable nature of steam penetration through fine lumen, means that effective sterilization of such air water syringe tips cannot be guaranteed. Therefore, the use of a disposable air water syringe tip to cut cross-infection risk is to be strongly encouraged."
