DID YOU KNOW?
New research shows that even one fluoride varnish treatment per
year can reduce cavity rates by 50% for children in the 6 month to 3½ year age
range. Additionally, more dentists are now using fluoride varnish on adult
patients who are at high risk for developing caries. In addition to helping
combat a rising caries rate in adults, the preventive varnish treatment can
increase hygiene production in the dental practice.
Latex gloves were first used by health care providers in
1883 at Johns Hopkins Hospital in Baltimore, Maryland. A surgical nurse,
Caroline Hampton, developed a rash from chemicals she handled while assisting
with surgeries. Dr. William S. Halstead, the surgeon with whom she worked,
contacted Goodyear Rubber Company to manufacture gloves. Nurse Hampton
demonstrated great dexterity while wearing the gloves, demonstrating their
value to others. By 1884, the gloves were in regular use by medical personnel
at Johns Hopkins Hospital, spreading from there to become standard use in
surgical procedures across the country.
By 3000 BC, Egyptian embalmers practiced disinfection
procedures using a mixture of resins (organic plant and tree secretions),
naphtha (a flammable liquid hydrocarbon mixture used as a solvent or diluter), liquid
pitch (the residue of a variety of organic materials including tar, resins from
conifer trees, etc.), vegetable oils, and spices. Aren’t you glad you can
purchase disinfecting agents rather than alchemically concocting your own? J
