The Need to Flush HP Air Lines
A BBC Panorama television program highlighted some very disturbing facts relating to Human Dentistry
and the HIV virus (FIV and FeLV behave in a similar fashion).
NOTE – Universities store their research FIV virus in glycerine, the main ingredient in Prophy Paste.
1. High Speed Hand Piece Turbines still spin after the drive air has stopped (foot taken off the foot con-
trol) and act as a centrifugal pump and suck back air and water plus debris into the turbines.
2. The human aids virus can live in debris in Dental Hand Pieces for as long as 2 months.
3. An article in the British Medical Journal “the Lancet” showed that HIV Virus may live in the striations in
Stainless Steel hand instruments.
4. Dr Leigh West-Hyde from Davis University in California said in the Manual of Small Animal Dentistry
“one drop of saliva may contain up to 600,000 Bacteria” “a Spoon Excavator of dental Plaque may con-
tain an average of 200 million Bacteria”. “The under surface of a fingernail can harbor residual blood
and bacteria for up to 5 days when gloves are not routinely worn”.
5. Autoclaving is the only sure way to sterilize Dental Instruments and Hand Pieces.
6. Feline aids virus is being reported in an increasing number of cats – up to 30% of the sick population.
7. Prophy heads washed under the tap after use still showed signs of blood coming from the drive mecha-
nism (TV program).
iM3 has developed a new solution and method of dispensing it into the air and water lines of Veterinary
Dental Units. It may also be used in the water system of Ultrasonic Scalers.
CLS is designed to mask the smell coming from animal’s mouths, drilling of tooth enamel and bone. It will
reduce bur cutting time by up to 10% and improve bur life.
A 0.12%Chlorhexadine (CHX) has been added as a preservative as the solution contains Glycerine. The
CHX at 0.12% is the strength recommended by most veterinary dental experts for use in the mouth with
animals. The CLS solution uses distilled water and will not clog valves, block HP, or lines in Dental Sys-
tem, whether air driven or ultrasonic.
The new delivery and flushing system is designed to deliver CLS solution to the HP. There are certain
instances where CHX should not be used, in the ear etc. In this instance the system is then switched back
to the standard water supply, or for prolonged periods in cats, as they are sensitive to CHX, always pack
the back of the throat to prevent debris or solution going down the throat.
Flushing with CLS is through the HP air lines (not water lines as normal) a moment switch is held of 1
second, approximately 1ml of CLS solution then enters the HP air lines. The HP is removed from its
holder and the foot control pushed. This will flush the CLS through the HP, any orifices in the HP head
and then return the bulk of the solution through the exhaust line to the collection bottle.
For complete bacterial removal, dismantling and autoclaving is the only sure method. Remember one new
Prophy cup per patient, we recommend R & R oscillating prophy heads.
The Glycerine in the CLS solution will also aid in the lubrication of the turbines. Tri flo Teflon lubricant
should still be used for lubrication.
