Frequency of cleaning teeth	0.71	0.0027	0.00	1.68 (1.60, 1.76)
Frequency of between-meal sugar consumption	0.65	0.0014	0.00	1.20 (1.14, 1.26)
Dental visit	0.73	0.0012	0.00	1.16 (1.10, 1.23)
Dental fluorosis	0.76	0.0026	0.00	1.91 (1.85, 1.98)

Variables – school: tribal and other government schools; gender: male and female; frequency of cleaning teeth: sometimes or once a day and more than once; frequency of between-meal sugar consumption: one time and more than one; dental visit: never and more than once; dental fluorosis: absent and present.
