N = 50 university students and employees brushed their teeth at two occasions, one week apart, using either a commercial ergonomically designed manual toothbrush (MT) or Brushalyze V1 (BV1), a manual toothbrush with a thick cylindrical handle without any specific ergonomic features. Brushing behaviour was video-analysed. Plaque was assessed at the second occasion immediately after brushing. Participants also rated their self-perceived oral cleanliness and directly compared the two brushes regarding their handling and compared them to the brushed they used at home.<h4>Results</h4>The sBMC oral health757https://www.ebi.ac.uk/biostudies/studies/S-EPMC11218271biostudies-literatureIt is the habit not the handle that affects tooth brushing - a randomised counterbalanced cross over study with young and healthy adults.PMC11218271Gotz-Hahn FWeik UBottenbruch CSick BEidenhardt ZSohrabi KStenger MBerneburg NDeinzer RKraft DfalseIt is the habit not the handle that affects tooth brushing - a randomised counterbalanced cross over study with young and healthy adults.<h4>Objective</h4>To assess the effect of the toothbrush handle on video-observed toothbrushing behaviour and toothbrushing effectiveness.<h4>Methods</h4>This is a randomized counterbalanced cross-over study.
