. A previous crossover study showed that a watch‐and‐follow instructional video improved plaque removal by an electric toothbrush compared to the use of the instructional leaflet. This study employed a parallel design to assess the value of an instructional video for plaque removal by a new model oscillating/rotating/reciprocating electric toothbrush. 2 groups of 26 dentate subjects with average oral hygiene, who had never used an electric toothbrush, participated in this single blind, randomised parallel group designed study. On day 1 of the study, subjects received a professional prophylaxis to remove all plaque. Oral hygiene measures were then suspended and subjects returned on day 3 when a prebrushing plaque score was recorded by plaque index and area. Subjects withdrew and either read the manufacturers instructional leaflet (group L) or observed the instructional video (group V). Groups L and V then performed toothbrushing with toothpaste for 2 minutes and with group V brushing in time with the instructional video. Post‐brushing plaque indices and areas were then recorded. Whole mouth, lingual, upper, lower, anterior and posterior but not buccal % reductions in plaque index and area were significantly greater in group V compared to group L. % plaque removal was also significantly greater by area at mid and distal sites but not mesial sites. Whole‐mouth plaque reductions were 10% greater in group V but reached >15% at lingual surfaces. Within group differences in plaque removal at paired sites e.g., buccal/lingual, remained similar, suggesting that further improvement could be achieved by modifying the video to devote more time to the difficult‐to‐clean areas. In conclusion, in the early period of learning the use of an electric toothbrush, plaque removal can be improved by using an instructional video. Such watch‐and‐follow video routines could be extended to other areas of oral hygiene practices.
