The Effects of Oscillating-Rotating Electric Toothbrushes on Plaque and Gingival Health

The Effects of Oscillating-Rotating Electric Toothbrushes on Plaque and Gingival Health: A Meta-Analysis

The aim of this analysis was to compare the effects of oscillating-rotating (O-R), side-to-side (sonic), and manual toothbrushes on plaque and gingival health after multiple uses.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Bleeding Sites	Change from baseline as measured on number of bleeding sites ( via gingival bleeding index, Loe Silness index, Papillary bleeding index or Mazza gingival index).	Up to 12 weeks
