简要总结
The objective of this single-use, examiner blinded, randomized, two-period, cross-over, IRB-approved clinical study is to evaluate the safety and plaque removal efficacy of AutoBrush®, a new children's 360° sonic toothbrush, compared to a marketed children's manual toothbrush.
详细描述
Up to 22 healthy children (5-8 years old) will be enrolled in a single-center, single-use, randomized, two-period, IRB approved cross-over study. Subjects will be randomly assigned to one of two treatment sequences: 1) brush two minutes with marketed children's manual toothbrush (MTB) or 2) brush 30 seconds with AutoBrush® 360° Sonic Toothbrush (AB) and fluoride toothpaste. Qualified subjects will have pre-brushing supragingival plaque levels ≥ 1.8 according to the Lobene-Soparkar Modified Turesky Modification of the Quigley-Hein Plaque Index (PI), following 12-16 hours plaque accumulation period. Under parent's supervision, subjects brushed at home with their assigned toothbrush, twice daily during a 2-day familiarization period. After refraining (12-16 hours) from oral hygiene, subjects returned for plaque assessment, supervised use of their assigned toothbrush and a post-brushing plaque evaluation. Subjects were given the second toothbrush to begin the next 2-day familiarization period and second period evaluation procedures. Analysis of covariance (ANCOVA) will be used for single-use brushing PI models to assess whole mouth and 8 other hard-to-reach tooth sites.

结局指标
主要结局
Within-Treatment Whole-Mouth Differences (vs Baseline) - Plaque removal Mean Change from baseline (pre-brushing to post-brushing) in plaque score after single supervised use based on all tooth surfaces of the whole mouth.
时间窗: Up to 2 weeks
Supragingival dental plaque: Lobene-Soparkar Modification of Turesky Modification of Quigley-Hein Plaque Index Plaque will be disclosed using a red disclosing solution and each tooth will be scored in six areas (disto-buccal, mid-buccal and mesio-buccal, disto-lingual, mid-lingual and mesio-lingual), according to the criteria noted below: 0 = No plaque. 1. = Separate flecks or discontinuous band of plaque at the gingival (cervical) margin. 2. = Thin (up to 1 mm), continuous band of plaque at the gingival margin. 3. = Band of plaque wider than 1 mm but less than 1/3 of tooth surface area. 4. = Plaque covering 1/3 or more, but less than 2/3 of tooth surface area. 5. = Plaque covering 2/3 or more of tooth surface area.
