Reduction in caries rate among patients with xerostomia using a power toothbrush.

The purpose of this study was to evaluate whether the use of a Sonicare toothbrush could be beneficial in reducing coronal and/or root caries among patients with medication-induced xerostomia. Eighty subjects with drug-induced xerostomia using either a Sonicare toothbrush (SC) or a manual toothbrush (MTB) were included in the study. Control subjects using a MTB were frequency-matched to 40 subjects using a SC, based on age, gender, number of teeth at baseline, and salivary flow rates.

The purpose of this study was to determine if using a Sonicare toothbrush was a beneficial treatment of xerostomia. Sixty-one subjects with medication-induced xerostomia were randomly assigned a Sonicare (SC) or manual toothbrush (MTB). Subjects were followed for four visits (one month apart); after two months, the MTB group crossed over to using a SC.
