Objective	To compare the plaque removal and gingivitis reduction ability for the Sonicare
	FlexCare (ProResults brush head) and Oral-B P-40®manual toothbrush in
	orthodontic population.
Methodology	Ninety-five healthy orthodontic subjects aged 12 years and older participated in a
	single-blind, randomized, parallel group clinical study assessing gingivitis and plaque
	over time for the Sonicare FlexCare and a manual toothbrush. All subjects were
	routine manual toothbrush users. At Visit 1, subjects were screened for eligibility
	(Modified Bonded Bracket Index (BBI) >2.0; Pocket depth ≤ 4mm). At Visit 2,
	subjects received a prophylaxis and were randomized to a treatment arm. Subjects
	were trained and given brushing instructions to use the assigned test device twice
	daily at home for two minutes. Subjects abstained from oral hygiene for 12-24 hours
	before each visit. At subsequent visits, safety and BBI were assessed before and after
	a two minute supervised brushing. Secondary efficacy measurements included
	Turesky-Modified Quigley-Hein Plaque Index (TPI) on tooth surfaces without
	brackets and a full-mouth Löe and Silness Gingival Index (LSGI). ANOVA was used
	for statistical analysis.
Results	The Sonicare FlexCare demonstrated superior plaque reduction in a single brushing
	on the buccal (bracketed) surfaces assessed by the Bonded Bracket Index compared
	to a manual toothbrush at the two-week and four-week evaluations (overall p<0.0001
	at two weeks, p<0.0001 at four weeks).
	The Sonicare FlexCare demonstrated significantly superior reduction in plaque over
	time (two and four weeks) on the lingual surfaces assessed by the Turesky-Modified
	Quigley-Hein Plaque Index compared to a manual toothbrush (overall p=0.0221 at
	two weeks and p=0.0025 at four weeks).
	The Sonicare FlexCare demonstrated significantly superior plaque reduction in a single
	brushing on the lingual surfaces assessed by the Turesky-Modified Quigley-Hein Plaque
	Index compared to a manual toothbrush at the two-week and four-week evaluations
	(overall p=0.0001 at two weeks, overall p<0.0001 at four weeks).
	The mean scoring Löe and Silness Gingival Index value was low (1.14, std 0.10)
	indicating that the population presented with healthy gingivae. Both groups, however,
	were able to demonstrate statistically significant improvement vs. baseline over time
	(overall p<0.0001).
