Participants without periodontitis, but with at least two teeth (index teeth) showing GR \u22652\u2009mm were randomized to brush either twice daily with a MT or with a PT with a linear magnetic drive causing the round brush head to produce gentle micro vibrations along with oscillating\u2010rotating movements.

Furthermore, the amount of GR sites which improved \u22651\u2009mm or remained stable during the study period did not differ between MT and PT, but the number of sites worsened \u22651\u2009mm was significantly in favour for PT (MT 23 (25.5%) versus PT 10 (10.6%); <jats:italic>p<\/jats:italic>\u2009=\u20090.009).
