Objective To compare the brushing duration with the Sonicare FlexCare+ versus a manual
toothbrush after two weeks of home use.
Methodology Fifty-six healthy subjects (24 females, 32 males) were enrolled in an IRB-approved
randomized, parallel-design two-week study. At Visit 1, eligible subjects were
randomized to either Sonicare FlexCare+ Gum Care mode or a manual toothbrush
and were provided brushing instructions.They performed an on-site brushing session
immediately thereafter, which was timed and video recorded from behind a one-way
mirror for duration data collection. A home-use period of two weeks commenced
with the assigned product in order for subjects to familiarize with the device.At
Visit 2, the subjects were asked to brush with their assigned product.The recording
procedure was repeated. Subjects were remunerated and dismissed. Statistical
analysis was performed using the Wilcoxon signed rank test.
Results Twenty-eight subjects were randomized to Philips Sonicare FlexCare+ and twenty-
eight to a manual toothbrush.A longer median brushing duration was observed
for Philips Sonicare FlexCare+ users at both time points. Sonicare FlexCare+ (180
seconds) compared to a manual toothbrush (90 seconds) at Visit 1 (p<0.0001).
Sonicare FlexCare+ (181 seconds) compared to a manual toothbrush (71 seconds)
at Visit 2 (p<0.0001).
Conclusion Subjects brushing with Philips Sonicare FlexCare+ using Gum Care mode brushed
signicantly longer (p<0.0001) than with a manual toothbrush following
a familiarization period of two weeks.
