Hollow electric toothbrushes are more bacterial growth

According to the latest study researchers University of Texas Health Science Center at Houston School of Dentistry conducted, the real heart of the electric toothbrush toothbrush less than the short retention bacteria.


Integrated media reported on September 2, according to the latest study researchers University of Texas Health Science Center at Houston (Houston) (UTHealth) School of Dentistry conducted, the real heart of the short electric toothbrush toothbrush than bacteria retained less. In this study, published in the August journal “Dental Health” in years, the chief author, Professor Houston Health Science Center School of Dentistry University of Texas Donna? Warren? Morris (Donna Warren Morris) said that, during the 10 experimental comparison, there are a small number of microorganisms nine times using the real heart of the toothbrush in the experimental group than in the residual short toothbrush experimental groups.

“Toothbrush passed microbes causing disease or infection. Real heart design lead to bacterial growth and fewer bristles should be soft, made of nylon,” Morris said. “Disinfect toothbrush and dry when not in use is very important to keep the toothbrush. Now some electric toothbrush comprises an ultraviolet system, or you can rinse the brush soaked in water for up to 20 minutes.”

The study was carried out for three weeks, the subjects were asked to brush their teeth twice a day using a random electric toothbrush. Subjects using non-antibacterial toothpaste and floss routinely continued throughout the experiment, but prevents the use of other dental products such as mouthwash.

“Most of the electric toothbrush packaging does not show is the real heart or short toothbrush design,” Morris said. “The best way to identify the real heart of the design is general, there will be two parts connected at some space, but a large part of the solid by observing its connection between the main electric toothbrush until the bristles or brush section. “

In the study, the brush head is exposed to five oral microorganisms: anaerobic and facultative anaerobic microorganisms, yeasts and molds, oral streptococci and enterococci oral anaerobes, Porphyromonas gingivalis and prismatic Aeromonas spp. The article also highlights the research is not yet published showing the growth of bacteria on the toothbrush may cause the system to the health effects, but Morris said several microorganisms are associated with system diseases. “We know there are some studies have found prismatic genus and colon cancer, and some other bacteria are associated with cardiovascular disease,” Morris explained. “There is a high correlation between gum disease and cardiovascular disease, the researchers cultured the same bacteria live in the vicinity of the heart, which can lead to gum disease.”
