Long-term impact of powered toothbrush on oral health: 11-year cohort study

This study aimed to assess 11-year longitudinal effects of powered toothbrush on periodontal health, caries and tooth loss in an adult population.

In the long-term, powered toothbrush seems to be effective in reducing mean PD (Probing Depth ) and mean CAL (Clinical loss of attachment ) - bothe measures of checking gum disease progressions, besides increasing the number of teeth retained.
