    I was surprise it was this low. The wording of the study result is a bit different, it’s not % of effectiveness, it’s a % reduction in plaque.

    The evidence produced shows benefits in using a powered toothbrush when compared with a manual toothbrush. There was an 11% reduction in plaque at one to three months of use, and a 21% reduction in plaque when assessed after three months of use. For gingivitis, there was a 6% reduction at one to three months of use and an 11% reduction when assessed after three months of use. The benefits of this for long-term dental health are unclear.

      That’s what effectiveness means, since removing dental plaque isn’t a binary thing. If you’re trying to remove plaque, then a percentage reduction is a corresponding increase in effectiveness. If a vaccine has a 20% reduction in disease compared to another vaccine, it’s 20% more effective at preventing the incidence of disease. I’m pretty sure this comment isn’t just splitting hairs; it’s actually wrong in its pedantry.
