All about enzymes


Enzymatic cleaners, commonly found in dental practices, are popular because of their ability to break down soils, stains, proteins and other debris with the use of natural enzymes. But have you ever wondered why they work so well? Here are some bitesize facts about enzymes and enzymatic cleaners you may not already know:

  •  Enzymes are responsible for many essential biochemical reactions in microorganisms, plants, animals, as well as human beings, and as such are crucial to life processes.
  •     Enzymes are biological catalysts. There are optimum temperatures, pH values and combinations with other chemical ingredients at which their activity is greatest.
  •    Enzymes help to speed up chemical reactions, giving them their valid reputation for being efficient cleaners.
  • The 1960s saw a new generation of enzymatic cleaners. When used in commercial laundry detergents, the addition of enzymes increased the capability of detergent to clean clothes. It wasn’t until much later that enzymatic detergent cleaners became available for dental facilities.
  •  There are thousands of enzymes involved in everything from the cellular processes in our bodies to the decomposition of our rubbish, but enzyme cleaners are made using a few specific enzymes that break down biological substances such as fats, oils, proteins and starches.
  • When used as part of the cleaning process, enzymes effectively reduce the need for more aggressive chemical ingredients in instrument reprocessing, reducing the environmental impact.
  •  Along with environmental considerations there is a growing demand for cleaning products that are pH neutral and alcohol free, as these are widely perceived as being less aggressive both to the materials and surfaces they are cleaning, as well as to the people that are using them.
  • Dentizyme is a low foaming, pH neutral enzymatic detergent for manual and ultrasonic instrument cleaning.

The importance of testing and validation

Testing and validation of decontamination and sterilisation equipment is a vital aspect of every practice’s decontamination procedures and should be clearly laid down in their infection control policy. This equipment is at the forefront of the battle against protein residues and cross contamination so ensuring it is operating according to manufacturers’ specifications is an important first step in identifying possible shortfalls in performance.

Validation provides a guarantee that decontamination equipment is working to manufacturer’s specifications, showing it complies with CE-marking under the terms of the Medical Devices regulations and that all instruments cleaned by the equipment are reprocessed reliably and consistently.

 Testing, on the other hand refers to the routine tests that must be carried out on a daily, weekly or quarterly basis to ensure that equipment meets validated parameters. The results of these tests should be accurately recorded to provide the evidence of compliance that is required by the relevant regulatory bodies.

For example, a weekly protein residue test is a simple but crucial test designed to detect residual proteins left behind on dental instruments and therefore assess the effectiveness of the equipment in terms of protein removal. This test is carried out on instruments cleaned in both washer disinfectors and ultrasonic baths. Washer disinfectors and ultrasonic baths should also be routinely checked, according to manufacturers’ instructions using a simple efficacy, or soil test, which identifies any problems with cleaning processes such as clogged or broken spray arms or deficiencies in the detergent used.

 Dentisan has long been at the forefront of testing and validation requirements and offers a full range of tests that a practice needs to fully audit the performance of washer disinfectors, ultrasonic cleaners and autoclaves on a daily, weekly and quarterly basis. Distributed via Henry Schein Dental, dentisan’s complete range of testing and validation indicators, provides total peace of mind and evidence of compliance for every dental practice.

Golfers tackle tough course at Dentisan’s inaugural golf day

When Commercial Director at Dentisan, Bob Newsome, chose May 3rd for the first ever Dentisan golf day, he envisaged a calm gentle day, with blue skies, a smattering of white cloud and possibly a little sunshine. And although May 3rd 2017 looked promising at 7am, by the time the 30 or so golfers had gathered at Sherwood Forest Golf Club, the weather had deteriorated somewhat. So, although rain was avoided, a challenging wind made what is a tough course in the most benign conditions, a real test of skill.

Sherwood Forest Golf Club, nestles in the Nottinghamshire countryside, and in previous years has been used as a qualifying course for the British Open. The course proved a real test of skill and nerve for the gathering of mixed ability players. The Club Professional gave a few pointers before the teams made their way to the first tee and with prizes for leading team, leading individual, longest drive and nearest the pin, there was plenty to play for.

The day was extremely well supported and Bob had managed to create a balanced blend of guests from the profession and the industry, with Dentisan’s exclusive dental distributor, Henry Schein, joined by representatives from the Corporate Dental Community, Practice Associates, the industry’s leading publishers and Dentisan’s lawyers and accountants, for what was a highly enjoyable and competitive day.

After almost five hours out on the challenging course, the players gathered for dinner and the prize-giving. Andy May, Sales Executive at the BDJ won longest drive with an enormous hit on the 13th, nearest the pin on the par three 4th, went to Duncan James from Shakespeare Martineau solicitors and nearest the pin in two, on the par four 18th was awarded to Paul Holmes from BUPA.

The winning team comprised Donal Flynn from BUPA, Ken Finlayson (FMC) and Duncan James. Duncan completed an excellent day by becoming the overall winner of the Dentisan Golf Day, carding a very creditable score of 38 and he was presented with the trophy by Dentisan’s Financial Director, Helen Wigglesworth (pictured).

Commercial Director at Dentisan, Bob Newsome was delighted with the turn-out and the whole day. “I am extremely grateful that so many of our friends from within the dental community have taken time out of their busy schedules to support this event and I look forward to welcoming them all again next year, for what I hope will become an annual date in the calendar.”

Delivering education and compliance straight to your practice

In my role as Business Development Manager at Dentisan, along with my colleague Ann, we visit many dental practices across the UK to help them in the area of decontamination and cross-infection control. It’s not just a case of telling people about Dentisan’s products, rather our aim is to give all dental professionals a much wider education about CPD requirements and the compliance needed within dental surgeries.

Our commitment to education is at the heart of what we do. As part of our Dentilearn programme, we publish CPD articles on our website and offer a City & Guilds accredited one-day decontamination courses as well as contributing to evening decontamination seminars run in association with Henry Schein Dental.

We appreciate that the problem in any busy practice is finding the time to allow key members of staff to go out for essential training, so we’ve turned this problem on its head and introduced Dentilearn CPD In-Practice. In other words, we bring the training to you.

The advantage is that we can come into your practice whenever it’s convenient - whether that’s lunchtime, after-hours or on a specific date. No one needs to take time out of the practice. You get to save on travel costs and the team remains in the comfort of their own surroundings.

Dentilearn In-Practice offers a choice of one- or two-hour CPD sessions covering a variety of topics which can be selected in advance to provide the specific training that best meets the needs of the individual team. The one-hour lunch sessions are very popular as they fit in well for everyone concerned. This also applies to the two-hour sessions for after-hours training.

There’s no maximum number of participants, so these sessions offer real value for money. I recently held a two-hour session for a team of ninety, then went on to do a one-hour session of just six. It simply depends on the number of staff in a practice or group of practices. The sessions are not product driven in any way; they are purely about staff gaining verifiable CPD and ensuring everything relates back to local guidelines, whether that’s in England, Wales, Scotland or Northern Ireland.

My aim is not just to visit a practice, provide the training and leave. I can carry out free water quality tests of dental unit water lines and offer advice should remedial action be required. I also walk through the practice and look at the decontamination and cross-infection protocols and answer any questions the team may have. It’s all part of the service.
