Effect of a Multidirectional Power Toothbrush and a Manual Toothbrush in Individuals Susceptible to Gingival Recession: A 12-Month Randomized Controlled Clinical Study

摘要: Background: Clinical studies have explored the relationship between toothbrushing and development of gingival recession (GR), but relevant GR data for multidirectional power toothbrush (PT) are lacking. The aim this study is to evaluate effect brushing with either a PT or American Dental Association reference manual (MT) on mid-buccal preexisting (PreGR) during 12 months.Methods: This was 12-month prospective, single-masked, parallel-group, randomized, controlled clinical study. Healthy participants without periodontitis at least two teeth showing PreGR ≥2 mm were randomized group an MT PT. primary outcome parameter change sites mm. All clinically based measurements performed by one calibrated examiner baseline, 6, months. Secondary outcomes changes all (with PreGR), in percentage demonstrating ≥1 mm, chang...
