UV sanitizer for various power
toothbrush heads
Hix J, Elliott N, De Jager M. Data on file, 2007.
To evaluate in vitro the ability of the Sonicare UV sanitizer to reduce viability of
microorganisms on several types of brush heads of power toothbrushes.
Several in vitro studies were executed examining various microorganisms and brush
heads. In each study, clinical conditions were mimicked carefully: brush heads were
artificially contaminated with a selected microorganism in a two minute "brushing"
cycle, then rinsed with tap water and sanitized using the 10-minute cycle of exposure
to the germicidal ultraviolet light of the UV Sanitizer. Non-treated brushes served as
a control. Commonly observed microorganisms were tested, including Escherichia
coli, Streptococcus mutans and Herpes Simplex Virus type 1 (HSV 1). Investigated
brush heads included the Sonicare Elite standard brush head, the Sonicare FlexCare
regular-sized and small ProResults brush heads, the Oral-B Professional Care
FlexiSoft® and FlossAction brush heads, and the National® Doltz EW910 and
EW920 brush heads.1,2
Following this procedure, it was demonstrated that the UV Sanitizer could reduce up
to 99% of E. coli, S. mutans and HSV 1 for the brush heads tested in this study.
The Sonicare UV Sanitizer effectively kills up to 99% of select microorganisms on
selected toothbrush heads.
