Abstract

Abstract : Background: Clinical studies have explored the relationship between toothbrushing and development of gingival recession (GR), but relevant GR data for the multidirectional power toothbrush (PT) are lacking. The aim of this study is to evaluate the effect of brushing with either a multidirectional PT or American Dental Association reference manual toothbrush (MT) on mid‐buccal preexisting GR (PreGR) during 12 months. Methods: This was a 12‐month prospective, single‐masked, parallel‐group, randomized, controlled clinical study. Healthy participants without periodontitis with at least two teeth showing PreGR ≥2 mm were randomized to a group brushing with either an MT or PT. The primary outcome parameter was change at sites with PreGR ≥2 mm. All clinically based GR measurements were performed by one calibrated examiner at baseline, 6, and 12 months. Secondary outcomes were changes of GR at all mid‐buccal sites (with or without PreGR), changes in percentage of GR sites demonstrating a change of ≥1 mm, and changes in probing depths. Results: A total of 107 participants completed the study (PT: 55, MT: 52). During the 12‐month study period the mean recession at sites with PreGR ≥2 mm decreased significantly from 2.2 to 2.1 mm in both groups ( P <0.05). The extent of GR parameters did not differ between MT and PT groups at any time point. GR evaluated clinically and on stone casts was well correlated. Conclusion: Neither the PT nor MT led to an increase in PreGR during 12 months of daily use.
