Variable	B	Standart error	β	P
Tooth brushing frequency	-7.918	2.174	-0.294	< 0.001
ICON complexity	3.388	0.773	0.379	< 0.001
Subjective treatment need	4.881	2.380	0.175	0.043

B: Unstandardized Regression Coefficients; β: Standardized Regression Coefficient; Tooth brushing: ≤ once daily (referent) and ≥ twice daily; ICON complexity grade scores (continuous); Subjective treatment needs: yes (referent) and no
