(57) Abstract : A method is proposed for analyzing the usage of a toothbrush made by a subject. The position of the
toothbrush is monitored using a position sensor on the brush, and the position of the teeth is monitored by a position
sensor mounted in a known fixed relation to the teeth. The resultant data is used to find the relative positions of the
toothbrush and teeth over time. Statistical analysis of this data permits the identification of habitual brushing failures
by subjects of the toothbrush. The toothbrush may transmit the output of its position sensor to a data analysis unit as a
wireless signal. The toothbrush may also be provided with further sensors, such as pH and pressure sensors, the output
of which is used in the statistical analysis to enrich the results.
