Since early model of powered toothbrush (Broxadent) was introduced in the 1960s, the design of powered toothbrush has changed significantly. Today powered toothbrushes can be categorized as mechanical and sonic. The main patterns of movements in the modern powered toothbrushes are oscillation, reciprocation, and rotational. Powered brushes especially helpful for people who have disabilities or dexterity issue. These brushes are also highly recommended for patients who require a larger handle because these are easier to grasp. By systematic review of Cochrane group in 2014, powered toothbrushes reduced dental plaque and gingivitis more than manual toothbrushing in the short and long term. Now we can recommend powered toothbrushes to people who need to enhance self-control dental plaque removal efficacy.
