Brushing machine for laboratory assessment of dentifrice abrasivety
The method is
used to examine the dentin abrasion by toothpaste in combination with a manual toothbrush in accordance with ISO 11609 ( ADA laboratory procedures , John J. Hefferren Phd. )
.
Furthermore, the method can be used
to determine the cleaning efficiency of plaque removal with a
toothbrush. The artificial teeth are preparing
with plaque (see drying of artificial plaque / staining test apparatus) . The samples are cleaned in the brush machine. After brushing plaque removal is analyzed with an image analyzing system
(see image capture of the remote plaque / Image analysis of Stain Removal) .
The device is equipped with 8 holders for
the specimen.
The stroke, the cleaning frequency, and number of cycles can be
set.
The
toothbrushes are mounted that they move in alternating directions with a small angle above the specimen. A defined load is applied to the brush and the specimen with brush head is immersed
in a tooth paste mixture. EN ISO 13849-1 Kategorie 3 und PL d.
