BOP = Bleeding on probing
β
Silness & Löe Plaque Index
Bold text = significant odds ratios
*
p-value >.05, but bootstrap 95% CI excludes 1.0
a
Potential mediator is not significantly related to the dependent variable
b
Mediation model was not tested because potential mediator was not significantly related to the dependent variable.
c
Reference group = White-Higher-SES
d
Reference group = “Suboptimal” oral hygiene (does not brush at least 2X/day and floss at least once a day)
e
Reference group = No dental visit in past 6 months
‡
“Optimal” = brushes at least 2X/day and flosses at least once a day
