Positive effects of Negative Ions for
Sterilization in a Clinical Environment
www.somamedical.net
Fundamental Principle Of Clinical
I.A.Q. (Indoor Air Quality).
Environmental Surfaces
Contaminated patient care items and surfaces pose different degrees of risk for infection
transmission based on their location and potential to transmit pathogens. With regard to
environmental surfaces, the latest precautionary clinical guidelines also provide a better
understanding of how to discriminate between the two categories of environmental
surfaces: clinical contact surfaces and housekeeping surfaces
Categories of Contaminated Environmental Surfaces
Category Definition Examples
Clinical contact Surfaces that are directly
contacted by contaminated
instruments, devices, hands,
or gloves
Dental unit surfaces, laboratory
equipment, reusable containers of
dental materials, drawer handles,
heavily used countertops, pens,
telephone handles, doorknobs
Housekeeping Surfaces that require regular
cleaning to remove soil and
dust but that rarely contact
dental personnel or patients
Floors, walls, lightly used
countertops
Environmental Decontamination
“A high level of general cleanliness must be maintained in clinical
surgery/treatment. Working surfaces, bracket tables and countertops should
be disinfected. The use of sterilize-able trays or disposables are
recommended. Floors, walls and sinks must be routinely cleaned. All spilt
blood or body fluids must be attended to immediately.“
The phrase “risk of aerosols contamination“ means :
1. “General cleanliness”, “routinely cleaned” are not enough.
2. “Spilt blood and body fluids” might not be attended too immediately.
3. Aerosol dispersal is not completely prevented by Using high-volume
suction and dental dam.
4. How many of dental clinics follow the exact IAQ preventive instructions?
5. Air conditioners make the air dryer (higher risk of droplet nuclei formation
because of fluctuating humidity levels)
Why is I.A.Q important in a clinical
environment?The execution of dental work and the use of various chemical compounds leads to
exposure levels for dentists, staff and patients to a range of potentially harmful airborne
contaminants. Especially for dental staff this exposure to potentially harmful air pollutants
can be significantly higher than that of individuals in most indoor environments.
Microorganisms
The use of high-speed drills and ultrasonic scaling equipment generates fine droplets which
are light enough to stay airborne for hours. Bacteria and viruses, which are contained in
these micro-droplets, are easily inhaled and constitute a potential source of infection.
Mercury
Numerous studies show that dentists and their staff have higher than average levels of
inorganic mercury (Hg) in their blood and urine. Mercury vapours can be released by the
placement and the removal of amalgam fillings. They may also be released from indoor
surfaces, where they may have accumulated over years of usage.
Disinfectants
Chemical disinfectants in a dental environment are responsible for a generally unpleasant
odour. Some disinfectants may also cause irritation and may have a sensitising potential
especially for staff.
The Clinical I.A.Q. Solutions
Temporary Solutions:
Using of disinfectants on surfaces. (Time
consuming and costly )
Long-lasting preventive solutions :
Slow releasing active chemicals (Titanium
Dioxide, TiO2), air filters, UV-C light and
negative ions.
So what is IAQ ?
Indoor Air Quality as defined by OSHA Malaysia,
OSHA Singapore and ASHRAE standard 62-1989.
“Wherein it is stated that air in which there are
no known contaminants at harmful
concentrations”. So quality air is always related
to fresh air.
Gases
� Volatile Organic Compounds (V.O.C).
� Potential VOC’s come from gases of building furnishings i.e. carpets,
furniture etc. and life cycle byproducts of micro-organism that lives in
the building (or its HVAC system).
� Aldehyde vapors are typical byproducts of both off gassing and
chemical processes, that occur inside or outside the building.
Particles
� Mostly counted in the diameter range from 0.1 micron or greater.
� Bio-aerosol are defined as airborne particles, which are living
organisms, spores and fragments of organisms released from living
organisms.
� These include pathogens (disease causing viruses), fungi (mold) and
bacteria.
Type of IAQ contaminants
3 main causes of IAQ problems
• Source of contamination
• Susceptible occupants
• Mechanism transport of contaminants
What I.A.Q problems should we be
concerned about?
1. How can people eject flu viruses into the air.
2. What different forms can airborne viruses take.
3. How far can those viruses travel & how can theycirculate within buildings and inside their HVACunits.
4. What conditions increase airborne flu virussurvival.
5. What systems are available to sterilize, captureand/or kill airborne flu viruses.
Airborne transmission depends on people to
launch viruses into the air. People can shed
this many drop nuclei flu virus into the air:
1. Coughing 3,000+
2. Sneezing 3,000+
3. Breathing 200+ natural sterilization , nose hair & mucus.
4. Talking/Singing 1,000+
5. Vomiting 1,000+
6. Diarrhea *20,000+
How far can Airborne Viruses Travel?
Large/Small Droplets Droplet Nuclei
1. Coughing 1-5 feet 160+ feet
2. Sneezing 8-15 feet 160+ feet
3. Singing, Talking 1-3 feet 160+ feet
4. Mouth Breathing 1-3 feet 160+ feet
5. Diarrhea* 5 feet+ 160+ feet
*As a result of toilet water aerosolization, air contamination in toilets
and gaseous pollutants into harmless products by a
process called photo catalytic oxidation (PCO).
• When applied as a coating and exposed to ultra-
violet or ambient light, Nano-TiO2 produces hydroxyl
radicals and superoxide ions that will neutralize
biological and gaseous contaminants in indoor air.

In essence, if we follow all five sterilization technologies
recommended by EPA, we would effectively have a 24/7 I.A.Q.A
solution protocol in place.
• We now know IAQA problems exist!
• We now understand the
recommendations by EPA for effective
sterilization!
• So, what kind of equipments and
technologies does Soma Medical have to
resolve these IAQA problems?
Soma Medicals **US$3,550
solution to what could
potentially be a “PRICELESS”
I.A.Q.A problem…..!!!
**We guarantee a post reduction in pathogens and microorganisms
after installation of our IAQA solution protocol. Estimate is based on a
floor area of 200sq.ft or 2,500 cu feet.

Actual Installation
The solution protocol would involve the IONS 8000 being switched on 24/7, the UVMax 14P with Ozone switch on only when there ARE NO OCCUPANTS in the room and the
