Abstract

Difference of toothbrushing motion between dental hygienists and mothers -Focusing on self-toothbrushing and caregivers’-toothbrushing

Highlights

  • Oral health is a vital component of wellbeing throughout life [1], and dental plaque control has become an essential target to keep good oral health [2]

  • The largest difference for displacement ranges for each axis was along the X-axis (2.12 mm), there was no significant difference between dental hygienists and mothers (Table 1)

  • Inada analyzed self-toothbrushing motion of dental hygienists using a motion capture system and suggested that twisting the wrist during buccal right side brushing limited the range of motion and made precise control of tooth brushing motion more difficult [5]. Considering these facts, in order to clarify the difference of the motion between dental hygienists and mothers, we evaluated tooth brushing motion on the left upper molars which are assumed to be easy to brush

Summary

Introduction

Oral health is a vital component of wellbeing throughout life [1], and dental plaque control has become an essential target to keep good oral health [2]. In the fields of dentistry, several studies have tried to evaluate brushing techniques in terms of tooth brushing motion three-dimensionally [5,6,7,8]. Et al demonstrated characteristics of tooth brushing motion and brushing force using a 3D accelerometer and a strain tension gage, and pointed out the need to analyze the tooth brushing motion at the individual’s cycle level because tooth brushing motion is a cyclic movement [6]. These previous reports focused only on self-toothbrushing
