In vitro effect of power toothbrushes on orthodontic bracket bond strength
|
Objective
To evaluate the effect of two new power toothbrushes and a manual toothbrush on the bond strength of orthodontic brackets bonded to human enamel using simulated clinical conditions
Methodology
Orthodontic brackets were bonded to 36 extracted teeth and exposed to Sonicare FlexCare power toothbrush or Oral-B P35 soft manual toothbrush for the equivalent of a two-year exposure to brushing in the presence of a toothpaste slurry.
After brushing, the force needed to debond the orthodontic brackets from the teeth was measured.
Results
There were no statistically significant differences in bracket debonding strength between any of the treatments (p>0.05).
Conclusion
This study demonstrated that the Sonicare FlexCare is safe to use for patients with orthodontic brackets compared to a manual toothbrush.
