Study & Design

Study Type: interventional

Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
The main aim of the study is to investigate whether synergisms are recognisable in terms of motor skills during toothbrushing and chewing and whether it is possible to change toothbrushing behaviour through the chewing process. A secondary aim of this study is to investigate whether it is possible to influence toothbrushing behaviour through the chewing process and subsequent toothbrushing instruction.

Secondary Outcome Measures

Name	Time	Method
Following the study, we want to investigate whether the tooth brushing instruction, which presumably led to an improvement in brushing behaviour in the first part of the study, still has demonstrable effects after a longer period of time and whether further instruction can increase the improvement initially achieved. In addition, we would like to investigate the reproducibility of the brushing frequency in order to support the interpretation of the previously identified correlations between brushing frequency and frequency of brushing movements.
