简要总结
Toothbrush plaque removal, along with interproximal flossing, helps to maintain the oral cavity free from periodontal diseases and dental caries. Although techniques such as the Bass Technique (BT), the Modified Bass Technique (MBT) and the Modified Stillman Technique (MST) are taught to dental students, dental hygiene students, and dental assistants, there is little evidence to discern which technique is more effective in reducing or preventing gingival inflammation.
At Tufts University School of Dental Medicine (TUSDM), a modification of the Bass intrasulcular technique is advocated to many students. We call this modification of the Bass technique a Stationary Bristle Technique (SBT), which is an intrasulcular technique that maintains the toothbrush bristle ends essentially stationary on the tooth cervically and in the gingival crevice.
In this study, half of the participants were taught the Stationary Bristle Technique Group, while the other half were not be provided with instructions, but asked to brush as normal (non-interventional group) throughout the duration of the study.
详细描述
This is a double-armed, randomized clinical trial. The primary aim of this study is to compare whether a Stationary Brushing Technique (SBT) is more effective in the reduction of gingival inflammation than permitting people to brush the way they normally do without instruction (Non-Stationary Brushing Technique).
Gingival inflammation is evidenced by the percentage (%) sites with Bleeding on Probing (BoP). The primary time-point will be at 4 weeks.
The amount of toothbrush bristle deformation at 4 weeks, 12, and 16 weeks of brushing with a SBT and with a NSBT will also be evaluated. 3. The secondary evaluation of BoP will be at the 12 and 16 week time-point.

研究组 & 干预措施
Stationary Bristle Technique (SBT)
Instructed brushing method. Participants are asked to brush twice daily, for 2 minutes at a time, following instructions for the Stationary Bristle Technique.
干预措施: Instructed Brushing Method (Other)
Non-Stationary Bristle Technique (NSBT)
The control group will be asked to brush twice daily, for 2 minutes at a time, following their normal toothbrushing technique.
结局指标
主要结局
Change in Gingival Inflammation
时间窗: From Baseline up to 4 weeks
Measured by the percentage of sites with BoP. The percentage of sites with BoP at each time point will be calculated by group
次要结局
- Change in BoP(From baseline up to 16 weeks)
- Toothbrush Bristle Deformation(From baseling up to 16 weeks)
