Is Your Sterilizer Sterile?

How do you test that your sterilizer for sterility?

You need a sterile Baseline for all the work in your lab to be consistent and reliable and as you run your cycles you can validate that the sterilizer works. There are two ways to validate your sterilizer:

  • One way is through a class 5 sterilization integrator
  • The other is weekly Spore testing

    Hand Piece Sterilization with Dry Heat

    We have addressed hand-pieces for the last couple years, successfully testing several different models including Dentsply, and others.  Below is a segment of an email sent to our sales reps concerning hand pieces.  Also, I have attached a flyer that we published last year concerning the RH-Pro11 and handpieces.

    Chuck,

    We have addressed handpieces for the last couple years, successfully testing several different models including Dentsply, and others.  Below is a segment of an email sent to our sales reps concerning handpieces.  Also, I have attached a flyer that we published last year concerning the RH-Pro11 and handpieces.

    Handpieces:  With the previous testing conducted under the COX FDA Clearance, handpieces were validated.  We recently conducted testing of the Neovo Dental and TEK USA handpieces which were subsequently validated, and we are in the process of seeking validation testing for Bien Air and Kavo handpieces.  Note of Interest:  The CDC Infection control dental guidelines focus on sterilizing the internal mechanism of handpieces which can easily be contaminated with patient material.  Unlike steam which requires direct contact of steam to sterilize, HVHA technology is a convective/conductive dry heat transfer process that dehydrates and kills microorganisms.  It is much easier to sterilize using HVHA than to rely on steam to seek out portals of entry to reach the narrow lumens of the handpiece internal mechanism.  Moreover with steam you have a lengthy drying process which is required by FDA and is a must for prolonging the life of the handpiece.  Because there is no water or steam involved with the RapidHeat HVHA technology, a total cycle for unwrapped handpieces using RapidHeat is FDA-Cleared for just 8 minutes.

    Hi Diane,
    Hand pieces will be an issue for many orthos,
    I read Bills response and out prior approval,
    but i really don’t know how modern hand pieces would react
    to RHT-1000.
    Would it be possible to have Sig test one and see the results?
    Thanks
    Chuck

    HI, hope the information we have sent you helps make a decision on a sterilizer.
    Have you decided on the COX?
    Any other questions we can help with?

    Hope this will help in making a decision: From MFG
    Cal or email with questions.

    Regarding our technology:  The COX RapidHeat High-Velocity Hot Air (HVHA) technology has been previously cleared by the FDA under 510(k) pre-market notification nos. K872643A and K881371.  The RH-Pro11 is simply a larger version of the COX RapidHeat sterilizer.

    Handpieces:  With the previous testing conducted under the COX FDA Clearance, handpieces were validated.  We recently conducted testing of the Neovo Dental and TEK USA handpieces which were subsequently validated, and we are in the process of setting up validation testing for Bien Air handpieces.  Note of Interest:  The CDC Infection control dental guidelines focus on sterilizing the internal mechanism of handpieces which can easily be contaminated with patient material.  Unlike steam which requires direct contact of steam to sterilize, HVHA technology is a convective/conductive dry heat transfer process that dehydrates and kills microorganisms.  It is much easier to sterilize using HVHA than to rely on steam to seek out portals of entry to reach the narrow lumens of the handpiece internal mechanism.  Moreover with steam you have a lengthy drying process which is required by FDA and is a must for prolonging the life of the handpiece.  Because there is no water or steam involved with the RapidHeat HVHA technology, a total cycle for unwrapped handpieces using RapidHeat is FDA-Cleared for just 8 minutes.

    Saturation Tests:  These tests don’t apply to the RapidHeat HVHA technology.  As alluded to above, the RH-Pro11 relies on conduction to permeate the working mechanism of handpieces and at the higher temperature of 375 degrees F. the HVHA technology is much more efficient than steam.
     
    Excerpt from another MEMO:
     
    We have been frequently asked about our HVHA’s ability to safely sterilize dental handpieces.  Please assure your customers that the temperatures reached in our HVHA family of sterilizers including the ground breaking workhorse in this technology, the COX RapidHeat Sterilizer are significantly less than the maximum 500 degrees F. operating temperatures of the Viton and Torlon components.
     
    In fact, as stated in the article whose link is provided below, the CDC unequivocally states: “Handpieces that cannot be heat sterilized should not be used”.  Dry Heat has been tested and proven to not degrade the handpiece operating life.  In fact dry heat would most likely add to the life of the handpiece due to the fact that no moisture or water is used in the process to potentially corrode and abrade the key operating components of the handpiece.  Also, we have been recently asked by a doctor if the fiber optics in his handpieces could be damaged or affected in any way by our temperatures, and the answer is repeatedly, NO, NO, NO.  Fiber optic glass fiber rods have an operating temperature of 900 degrees F. and therefore are not affected.
     
    http://www.rdhmag.com/articles/print/volume-31/issue-11/columns/sterilizing-handpieces.html
     
    The problem with many handpiece manufacturers, they don’t specifically state in their IFU that dry heat or HVHA/RapidHeat can be used, because all they know and have used in the past is “autoclaving” (steam sterilization).  We are moving forward to work with manufacturers of handpieces to correct this problem and to offer our sterilizers to validate and demonstrate that their handpieces are not in any way affected by dry heat sterilization. 
     
    AS A MATTER OF FACT IF I WAS A DENTIST AND I KNEW WHAT I KNOW ABOUT DRY HEAT, I WOULD SERVERLY LESSEN THE USE OF STEAM TO STERILIZE MY INSTRUMENTATION.  BY LESSSONING MY RELIANCE ON STEAM I COULD ALSO MINIMIZE THE HIGH COST OF OPERATING, MAINTAINING AND REPAIRING STEAM STERILIZERS.

    Hi Andrea  –

    We use W&H handpieces, and we start by running them through a SciCan Statmatic before we place in an M11.

    Can you advise about how the lubrication will react in the Cox Dry Heat sterilizer?

    Thank you.

    If you can advise what highspeed tools you have, we can check.

    Also we suggest, though this is not a dry heat sterilizer

    The COX sterilizers:
    Cox is approved for most high speed hand pieces , so is the rht1000
    Safety , it meets all UL and CE requirements

    Hello
    If you haven’t made a sterilizer decision yet, here is an amazing opportunity.
    A FDA approved sterilizer with more capacity than M11 and uses dry heat to do wrapped instrument cycles in 12 Minutes.

    Have you made any decisions on the COX?

    Hello Dr Justin Trimmel,

    The RH, is about 4-5 times the size of chamber from the COX 6000
    At this point expected release is Mid January.
