Adjusted Poisson regression models on the associations of decayed teeth, number of missing teeth, gingivitis and malocclusion, and OIDP^† stratified by socioeconomic position

	β	SE	RR‡	95% CI
Number of decayed teeth
Low family monthly income	0.080**	0.006	1.08	1.07–1.10
High family monthly income	0.127**	0.015	1.14	1.10–1.17
Number of missing teeth
Low family monthly income	0.104**	0.018	1.11	1.07–1.23
High family monthly income	0.163**	0.021	1.18	1.13–1.23
Gingivitis§
Low family monthly income	0.147**	0.013	1.16	1.13–1.19
High family monthly income	0.221**	0.024	1.25	1.19–1.31
Malocclusion¶

High family monthly income	0.662*	0.118	1.94	1.54–2.44

^*P < 0.05 and **P ≤ 0.001 are considered significant.

All analyses were controlled for age and sex.

^†Oral Impacts on Daily Performance (OIDP) extent: number of oral impacts, ranging from 0 (no impact) to 9 (impact in all activities).

^‡RR: rate ratio.

^§Number of sextants with bleeding on probing.

^¶DAI score.
