What all Dental Professionals should know about Chemical Fume & Digital Particulate

Chemical Fume
Methyl Methacrylate• Organic compound in colorless liquid
form used to make dental splints and various other dental prosthetics.
Typical exposure via
occupational
inhalation
MMA: Health Effects• Irritation to mucous membranes• Respiratory symptoms including chest tightness
and coughing• Neurological symptoms including headache,
lethargy, and lightheadedness • Reduced lung function • Cardiovascular disorders
MMA: Engineering ControlDuctless Fume Hood w/ Carbon Pre-Filter & Activated Carbon Filter
Activated carbon filter contains billions of granule pores to adsorb harmful chemical
fume.
Ductless technology requires zero exterior venting.
MMA: TestimonialDr. Paul M. Baraban D.D.S.Proud owner of a Sentry Air Systems Ductless Fume Hood
“I can’t tell you enough how wonderful it is making splints. I use to suffer headaches every time I smelled Methyl Methacrylate. When I did them the entire office smelled of it. Now that I have my hood I never have a headache and there is absolutely no smell in the office or lab area. Worth every penny!!! It is of great comfort that I am also not exposing myself and office staff to a potential carcinogen. I highly recommend this product to all my friends that make Maxillary Anterior Guided Orthotics or any splints for that matter.”
Ductless Fume Hoods
18-inch Wide SS-218-DCH
24-inch Wide SS-324-DCH
40-inch Wide SS-340-DCH
Other sizes and customizations available.
Digital Particulate
Ultra-fine Particles (UFP)• Particles less than 100nm in
size, invisible to the naked eye.
UFP is emitted
during 3D printing
operations
UFP: 3D Printing• 3D printers are used by dental
labs and dental offices to print molds, temporary implants, surgical guides and various other dental apparatuses.
Exposure to UFP via
inhalation
UFP: Health Effects• UFP can travel through the nasal passage and
into the head’s airways, potentially lodging on the brain.
• UFP can enter through the esophagus and implant on the lungs.
• UFP can accumulate in bone marrow and other major organs leading to serious health effects.
UFP: Engineering ControlPortable fume extractor with “python” style hose &
HEPA filter media
Portable fume extractor w/ flexible hose allows for greater source
capture of UFP.
HEPA filters with 99.97% efficiency on particles 0.3
microns and larger.
Children’s Museum of Houston
Particle scanner registered over 518,000 particles/ft3
inside the 3D printer during operation.
Model 300 w/ Python arm attached to printer exhaust port
Brent Richardson, happy customer
Particle scanner registered zero particles/ft3 in the
exhausted air after going through the fume extractor.
