Data on Toothbrushing Study Comparing Infrared-based Motion Tracking versus Video Observation

The MT system was developed for use in studies of toothbrushing habits as a potential substitute for the VO tool. The data was collected in 103 subjects who brushed with either a manual or a powered toothbrush.

Forty-six subjects completed 2 brushing sessions; the second brushing session took place after subjects had received video instruction aimed at improving their brushing systematics. In each brushing session, 2 CSV files were generated: 1 file from MT and 1 file from VO. Filenames are coded with the internal labelling of the subject (first 4 numbers), labelling of the first or second brushing session (“001” or “002”), labelling of the toothbrush device (P: power toothbrush, M: manual toothbrush) and labelling indicating whether the subject was a left- (“L”) or right-handed (“R”) user.
