Title The Use of Powered Toothbrushes Versus Manual Toothbrushes for Gingivitis
Clinical Question Does the use of a powered toothbrush with rotation oscillation reduce the presence of gingivitis more than a manual toothbrush?
Clinical Bottom Line If a patient uses a powered toothbrush with rotation oscillation there is a more beneficial decrease in gingivitis than if a patient uses a manual toothbrush. (See Comments on the CAT below)

PubMed ID Author / Year Patient Group Study type
(level of evidence)
#1) 12535436Heanue/2005There was a random group of 2,547 people who had no physical challenges hindering them from brushing their teeth. They were told to brush for at least 4 weeks. At the end of the 4 weeks they observed changes of plaque levels and gingivitis. Meta-analysis
Key resultsThe effect measure for each meta-analysis was the standardized mean difference (SMD) with the appropriate 95% confidence intervals (CI) using random effect models. At one to three months the SMD for gingivitis SMD -0.44 (95% CI: -0.72, -0.15). These represented an a 6% reduction on the Loe and Silness gingival index. At over three months the effects were SMD for gingivitis -0.51 (95% CI: -0.76, -0.25). These represented a 17% reduction on the Ainamo Bay Bleeding on Probing Gingival Index. Therefore, in the short term and long term, toothbrushes that use a rotation oscillation movement eliminated more plaque and decreased gingivitis more efficiently than manual brushes.

The Evidence
The evidence is the highest in the hierarchy of evidence with over 2500 subjects in the study.
Applicability The patient who is diagnosed with gingivitis can use this information and with the use of a rotation oscillation powered toothbrush can have a decreased plaque index which will in turn help reduce the gingivitis. Practitioners can use this information to better control their patients’ oral hygiene.

A PubMed search on this topic was completed in March 2012. After performing the search I feel that this CAT is of the highest level of evidence. I would feel comfortable making the statement, use of a rotation oscillation powered toothbrush decreases plaque index more efficiently than use of a manual toothbrush, thereby making it more beneficial in decreasing gingivitis.
