Effect of a Multidirectional Power Toothbrush and a Manual Toothbrush in Individuals Susceptible to Gingival Recession: A 12-Month Randomized Controlled Clinical Study.

Background: Clinical studies have explored the relationship between toothbrushing and development of gingival recession (GR), but relevant GR data for the multidirectional power toothbrush (PT) are lacking. The aim of this study is to evaluate the effect of brushing with either a multidirectional PT or American Dental Association reference manual toothbrush (MT) on mid-buccal preexisting GR (PreGR) during 12 months.

Methods: This was a 12-month prospective, single-masked, parallel-group, randomized, controlled clinical study.
