Fig. 1From: Good role models? Tooth brushing capabilities of parents: a video observation studyDistribution of TQHI scores prior to and after brushing (median and interquartile differences) in n = 59 parents. Scores 1 and 2 reflect sites at which the plaque is solely situated at the gingival margins, scores 3–5 indicate that plaque is also found in the 1st, 2nd and 3rd third of the crown, respectively. Increasing percentages of sites with score 1 and 2 after brushing indicate that participants manage to remove plaque at more coronal parts of the crown but not at the gingival marginBack to article page
