Table 5 Comparison of caries prevalence between groups

Parameter		African born vs Australian born	African born vs Other overseas born
Any visible caries	Crude PR [95% C.I.]	1.48 [1.08 – 2.03]	0.74 [0.58 – 0.94]
Any visible caries	Adjusted PR [95% C.I.]	1.35 [0.97 – 1.88]	0.73 [0.58 – 0.93]
Primary dentition
*dmft >0*	Crude PR [95% C.I.]	1.38 [0.75 – 2.56]	0.61 [0.34-1.08]
*dmft >0*	Adjusted PR [95% C.I.]	1.35 [0.73 – 2.50]	0.54 [0.32-0.90]
*dmft 6+*	Crude PR [95% C.I.]	0.69 [0.18 – 2.60]	0.22 [0.06-0.77]
*dmft 6+*	Adjusted PR [95% C.I.]	0.66 [0.15 – 2.50]	0.17 [0.05-0.56]
*Mean dmft*	p-value^	0.809	0.045
Mixed dentition
*dmft > 0 or DMFT > 0*	Crude PR [95% C.I.]	1.15 [0.84 – 1.58]	0.70 [0.57 – 0.85]
*dmft > 0 or DMFT > 0*	Adjusted PR [95% C.I.]	1.14 [0.82 – 1.57]	Did not converge
*dmft 6+ or DMFT 2+*	Crude PR [95% C.I.]	2.04 [0.71 – 5.83]	0.58 [0.26-1.31]
*dmft 6+ or DMFT 2+*	Adjusted PR [95% C.I.]	1.98 [0.69 -5.67]	0.57 [0.25-1.28]
*Mean dmft*	p-value^	0.13	0.033
*Mean DMFT*	p-value^	0.91	0.533
Secondary dentition
*DMFT >0*	Crude PR [95% C.I.]	1.79 [0.68 – 4.72]	1.00 [0.67 – 1.51]
*DMFT >0*	Adjusted PR [95% C.I.]	1.79 [0.68 – 4.74]	1.00 [0.66-1.50]
*DMFT 6+*	Crude PR [95% C.I.]	N/A*	N/A*
*DMFT 6+*	Adjusted PR [95% C.I.]	N/A	N/A
*Mean DMFT*	p-value^	0.18	0.367
Overall: any dmft > 0 or DMFT > 0	Crude PR [95% C.I.]	1.40 [1.07-1.85]	0.81 [0.65-1.02]
Overall: any dmft > 0 or DMFT > 0	Adjusted PR [95% C.I.]	1.24 [0.95 – 1.63]	Did not converge

^Two sample t-test of equal variance.
*A prevalence ratio for secondary dentition could not be calculated as there were no Australian-born children with severe caries and only one in the Other overseas born group.
