TECHNOLOGY MOVES ON IN DENTAL - APART FROM HANDPIECE MONITORING - FREE COURSE - FREE CPD POINTS!

Your handpieces are non-validated - meaning there is no evidence that they have been successfully sterilised if you tick the following boxes:

1. Using a plastic helix in the morning cycle
2. Using anything other than a class 2 in a metallic helix device on each cycle with handpieces
3. Using biological spore tests weekly or monthly
4. Using only the results of the self sealed sterilise pouches
5. Using any steriliser other than a B-Class Pre Vacuum

To understand how these work you must understand how the scientific standards work. The scientific standards (ISO), are NOT guidelines. Guidelines hold zero weight in your dental industry because they can neither validate processes nor will they enact liability for their claims.

Therefore we can only turn to the science of ISO.

Your standard is called AS 5369:2023 - this is also NOT a guideline.

Inside AS 5369:2023 there are direct references to ISO and European (EN) standards which themselves are embedded into AS 5369:2023.

Therefore AS 5369:2023 is merely a reference standard that only points to ISO/EN in order to get the answers to validate processes such as class indicators that validate handpieces.

We are offering FREE training on AS 5369:2023 and ISO/EN standards.

This will teach you how these standards work and how to apply them in your practice. This is vital for the safety of your patients and your practice.

WHY WASTE MONEY ON ACCREDITATION THAT DOESNT WORK?

Dental accreditation is a F-A-R-C-E

It doesn’t work and it cannot be measured.

How could it be possible for an accreditation to take place when no accreditor assesses your practice, assists in policy and manual writing, or trains any of your staff?

Today accreditations are ticklists that you do by yourself. You are the one who writes your manuals, you are the one who has to organise training for your staff, and worst of all, you are the one who is liable when taking bad advice.

No serious practitioner should place their practice in the hands of unqualified “accreditors”, unless they are willing to sign a declaration that they will take FULL LIABILITY for the information and “accreditation” they are providing. Shouldn’t there be assurances if you’re paying for it? But there isn’t.

It would be the same as having someone who is not a dentist and has no dental training to perform a filling or extraction for you. It’s quite laughable, but this is what is happening with your industry when it comes to accreditation, work health and safety and infection control.

The safest and most effective way to ensure your practice is secure and your patients are in safe hands is to conform your practice to the ISO accreditation. ISO is visible all across your dental practice from gloves to gowns to wipes to steri pouches to handpieces to scalers, to chairs to sterilisers to chemicals and even on your benches, office desks, doors and floors.

You are told to follow AS 5369:2023. But if you read AS 5369:2023 it tells you that it doesn’t have most of the answers, and rather points to ISO standards for full compliance.

This is what we will accredit you to. ISO standards and AS 5369:2023. So sit back, continue to see your patients and let us do all the work, compliance and even train your staff properly.

$2,995 for everything, including internal inspection and Audit report.

No deposit needed - payment done at the end of the process. No expiry date on accreditation.

DO WE EVEN NEED INDICATORS TO VALIDATE SOLID INSTRUMENTS? PRODUCT FAMILIES -Part Five

What about biological tests that are run each year by your technicians each year? Are they even required.

Those biological vials are 1-1.5ml of a biological spore. It’s not just any spore, but the most potent spore known to humans.

They place this into your steriliser each year when validation is done on your steriliser.

Most techs will provide a service on your steriliser each year. Part of this service is running biological spore tests. They are placing these spores into your chamber and simply hoping for the best.

These spores are then sent to a lab and incubated to see if there will be any growth. Typically there will be no growth in the chamber where the spore test is placed.

However if there is growth, then the steriliser cannot be validated. So what happens then? The technician may provide a loaner steriliser whilst the original steriliser is being repaired, however this will not solve the issue. The fact is that the original steriliser has a malfunction which possibly caused a breach.

From this point you would have to recall ALL INSTRUMENTS that were used from the last time you had a pass result with biological spores.

How many patients would you see in a year?

Then each patient would have to be notified to be tested for possible viral pathogens such as HIV, HEP B,C etc.

It’s a disaster waiting to happen.

Are biological tests even mandatory? No! Why are they not mandatory?

Because since the early 2000’s most B-Class benchtop sterilisers come with a chart printout. And as we now know, the chart printout provides more information than any biological spore test. Therefore why would we subject ourselves to possible fails with spore testing when they are no longer necessary?

And yet this is status quote in dental. Technology that has been outdated and not mandatory since 2003.

In conclusion, all solid instruments and biological spore testing is superseded by chart printouts.

Only when validating handpieces is a metallic PCD and Class 2 indicator required.

DO WE EVEN NEED INDICATORS TO VALIDATE SOLID INSTRUMENTS? PRODUCT FAMILIES -Part Four

As we explained, there are 4 critical parameters required to achieve sterilisation.

Temperature
Time
Steam Pressure
Air Removal

If one of these are missing, then sterility assurance simply cannot be achieved.

The chart printout is validated by the use of the internal sensors located inside the steriliser. However, these sensors are unable to read inside lumens. Therefore, they are unable to validate your sterility processes inside handpieces.

The reason for this is their incapability to detect air down to 1ml. The lowest reading they can provide is around 150ml air. Therefore, if your chamber has 149ml of air remaining inside the chamber, the steriliser will pass the load, as it has no clue how to detect the remaining 149ml of air. This is known as "porous level monitoring".

However, 149ml of air is enough to validate solid instruments such as scrapers, scalers, perio probes, scissors etc.

It does this by utilising its parameters listed above to a universal (porous) level. If you look at the chart printout (typically found in your PC memory sent via your steriliser each cycle), you will see all of the 4 critically listed parameters. Therefore, if you were to measure the chart printout up against the class 6 indicators, recommended by almost everyone (most useless indicator ever invented), then you would clearly see that the chart printout itself provides you with more information than every class indicator apart from class 2.

Therefore WHY would we be wasting time and money and effort on classes: 1,3,4,5,6 indicators?

The proof of this is right inside the pudding. Simple ask those who are pushing these class indicators into your practice to provide assurances in writing that "We guarantee that no patient will contract any cross contamination infection whilst using these indicators". Why not right? But of course you will never get this email. Because its all talk and zero liability.

The point of this is that we are simply on our own. Therefore we need something MORE than just "trust us, we know what we are talking about'.

The chart printout results are there to demonstrate all 4 parameters have been met.

We will discuss how the chart printout completely eliminates the use of biological testing in your clinics.

DO WE EVEN NEED INDICATORS TO VALIDATE SOLID INSTRUMENTS? PRODUCT FAMILIES -Part Three

For decades the wool has been pulled over your heads in dentistry when it comes to devices being used to validate sterility assurance.

Associations, sales reps and techs are telling you things such as:

“Use a plastic helix inside the morning cycle of the sterile each morning”.

But are you aware that the helix was NEVER invented for the morning empty cycle? It was invented only to validate handpieces. Therefore why are we even using it for our morning empty cycle?

Of course you will hear things such as “it’s invented to detect efficient air removal necessary for the validation of the steriliser each morning, or something to that effect, but this is totally false.

It’s a dummy handpiece - period! That’s what Albert Browne invested it for, and this what its purpose is.

Ask your technicians “WHY” is the helix 1.5m in length when stretched out? You will be “told” various reasons other than the REAL reason, which is back in the 1970s, sterilisers were positioned on the ground with submarine style handles - similar to a garbage top loading bin. Their internal free space was 1.5m cubed. Therefore a hollow tube 1.5m in length is longer than any handpiece, plus its hollow, therefore the steam would have to enter the chamber and spread itself across the equivalent of a 1.5m free space. All handpieces that occupy this space would hence be validated if we can validate the helix

Notice that this only works when placing the helix into cycles that contain handpieces? So why are we placing helix devices into empty chambers where there are no handpieces? It does nothing for us, and it’s completely waste of money.

Add up your annual costs for the morning helix test. What’s that number? Remove it, because you don’t need it.

Next, let’s explain what those built in chart printouts are for and how they eliminate the use of indicators for solid instruments.

We will explain in part four …..

DO WE EVEN NEED INDICATORS TO VALIDATE SOLID INSTRUMENTS? PRODUCT FAMILIES -Part Two

So how to we validate instruments?

This is why chemical class indicators were invented. Each indicator detects certain parameters present in the sterilisation process, but which parameters are vital for a device to achieve “Sterility Assurance Levels” (SAL)?

The answer is:

1. Temperature (134C)
2. Time (3min)
3. Air Removal (less than 1ml)
4. Steam pressure (15 psi)

If one of these parameters are missing in your process then you will NOT have any evidence that your instrument batch are sterilised.

So which indicators tick these boxes?

Class 1? No!
Class 3? No!
Class 4? No!
Class 5? No
Class 6? Definitely not! This is the worst of all classes

Only the Class 2 indicator can measure all 4 parameters above.

Therefore if you are using any other indicator, your batch of instruments could be heavily contaminated with bacteria and viruses and you have no idea this was the case.

Any patient could call for a WHS on the practice and then call for evidence that the instruments have reached validation - most practices can never produce this evidence - stating that you were “told” otherwise is not an answer.

The above information works for validating solid instruments only, but do we even need indicators to validate the above?

The direct answer is no.

We will explain in part three…..

DO WE EVEN NEED INDICATORS TO VALIDATE SOLID INSTRUMENTS? PRODUCT FAMILIES -Part One

You have been told many stories regarding “critical instruments” in dentistry.

You have been told that an instrument is deemed critical when it crosses the mucus or gum line in the mouth. This is also known as the “Spaulding Method”, named after Earle Spaulding, in the 1950’s.

But time moves on and science consistently recedes those pockets of outdated information. In 1992 the Spaulding Method was debunked by Seymour Block who provided both science and logic, building on from Spaulding rather than challenging him.

Today in dental schools and in many infection control courses, we continue to hear about the Spaulding Method being used and advised, when in fact it should not be.

As we all know, ISO Science is the be all and end all. There is no such term used as “critical instruments” in the ISO standards. Instead ISO use the term “Product Families”. Where vast ranges of devices and products are placed into categories and labelled “category A,B,C” etc.

Here are some examples

Linen: category G
Plastic trays: category F
Small fine solid instruments (perio probes, scalers etc): Category C
Handpieces: Category A

Therefore your handpiece is the MOST and ONLY critical instrument you have in dentistry. The reason for this is they are hollow lumens and cannot be taken apart for cleaning and sterilisation.

Therefore every other instrument in dentistry has zero bearing against the handpiece. If we can validate the handpiece then ALL other instruments therefore would validate long before the handpiece. Deeming the entire batch sterile and validated.

REPONSE TO THE MORTDALE PRACTICE INCIDENT

https://www.news.com.au/lifestyle/health/health-problems/sydney-dentist-safuan-hasic-potentially-exposed-patients-to-hiv-and-hepatitis-b-and-c/news-story/04586331527d2d5e32f1c0d4c43c2724?amp

And who is responsible here? Most dentists don’t even understand the requirements for infection control. Then you have the associations, sales reps and techs offering “advice” that is never backed up, nor indemnified - bad advice.

Then when an “outbreak” occurs all the attentions points to the dentists and not the industry for providing bad advice. The industry and associations throw their hands in the air and walk away - leaving the Dentists to fend for themselves

What about all that really bad infection control advice and information given to Mr Hasic over the years?

Does anyone seriously know any dentist in the country who purposely wants to place their patients at risk? Very unlikely!

The question is not WHY a steriliser from the “1950’s” was used. The question is: WHAT tools were used to measure its efficacy?

We all know the reality - dentists simply do as they are told when it comes to infection control. Hardly anyone understands what to do in these areas.

What you need to understand is there is a massive difference between Guidelines and standards. Standards are scientific where guidelines are not.

Inside your AS 5369:2023 standard is a list of ISO scientific standards. ISO rules the roost. All of your scientific validation lies within ISO standards.

Therefore WHY are we not using ISO standards when it comes to infection control for dentistry?

This incident with Mr Hasic should never have happened and both the federal and state governments should be encouraging dental practices to conform ISO standards.

Of course the REAL issue here would be that of the use of monitoring tools such as helix devices and class II indicators used to validate devices such as handpieces (your only critical instrument), as the handpiece is the only device that has the capability to transmit blood borne pathogens across from one patient to the next. But practices are not taught how to validate handpieces … why??? Because associations and industry haven’t a clue on how to validate handpieces.

If Mr Hasic’ practice conformed to ISO then this incident would never have happened.

It’s high time we start implementing what our scientific standards tell us to.

Patients of a Sydney dentist have been urged to get tested after they were potentially exposed to deadly-blood borne diseases.

How about the national law? Practitioners Act of 2025? This act points you to AS 5369:2023 in almost every section. Which means "we have no idea what to do - so go and consult AS 5269:2023"

Then you have the issue of AS 5369:2023 pointing you to ISO/EN scientific standards. "We (AS 5359:2023), also have no idea - so please purchase and consult all 30+ ISO/EN references for your answers.

Now wonder it is really confusing. Associations and committees for guidelines have no clue either. How could they? It takes years to learn how to interpret ISO science, not to mention apply it into practice.
