Significant correlations (r-value) between environmental factors and the independent factors of oral hygiene behaviour.
Significant (p ≤ 0.01) positive (full line) and negative (dotted line) correlations between environmental factors (parental care; negative experiences / feelings at / with dentists currently and during childhood; dental anxiety) and the 4 independent oral hygiene behaviour factors (factor 1 “attitude towards oral hygiene” (including sensations towards and during oral hygiene); factor 2 “attitude towards one’s teeth” (including perception of one’s own teeth); factor 4 “self-inspection of one’s teeth” (including actions for controlling one’s own teeth and the use of professional help). Only those results are presented exceeding the threshold of effect size (r2 > 5%).
