conducted and conclusions drawn using a linear
mixed effects model for repeated measures crossover
studies. Subject mean plaque scores obtained by
averaging overall sites corresponding to a single subject
on a given visit defined the computational unit
in statistical tests. Comparisons between groups
were performed using the overall F test of analysis of
variance. Analyses were carried out for full mouth,
anterior region, posterior region, interproximal sites,
and interproximal sites of the posterior region.
Results
Of the 92 subjects screened for the study, one
subject was disqualified because of a low plaque
score at the screening visit. All qualified 91 subjects
were included in the ITT analysis. Sample demographics
are shown in Table 1. Study subjects exhibited
moderate-to-high average plaque scores (range,
1.89-4.41) at the screening visit and were users of
manual toothbrushes. Excellent compliance with the
prescribed home procedures was reported by virtually
all subjects. During the first period, FlexCare and
Triumph users brushed 13.2 ± 0.47 and 13.3 ± 0.72
times, respectively. This high level of compliance
was maintained during the second period.
Efficacy data for the primary outcome variable
and additional information obtained from subregions
are listed in Table 2 and Figure 2. Subjects using
FlexCare achieved a statistically significantly greater
