Correlation matrix (Spearman coefficient) between age, family monthly income, dental caries, missing teeth, gingivitis, malocclusion and OIDP extent^†

	OIDP† (P)	Family monthly income (P)
Age	0.036 (0.009)*	0.047 (0.001)*
Family monthly income‡	−0.126 (< 0.001)*	1
Number of decayed teeth	0.254 (< 0.001)*	−0.250 (< 0.001)*
Number of missing teeth	0.152 (< 0.001)*	−0.130 (< 0.001)*
Gingivitis§	0.221 (< 0.001)*	−0.093 (< 0.001)*
Malocclusion¶	0.168 (< 0.001)*	−0.084 (< 0.001)*

^*P < 0.05 is considered significant.

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

^‡Family monthly income categories: ≤ R$ 500, R$ 501–1,500, R$ 1,501–2,500 and > R$ 2,500.

^§Number of sextants with bleeding on probing.
