Note. Cut-off point: a = mode, b = medium, and c = arithmetic mean. Statistics: n0 = number of cases < arithmetic mean or median, n1 = number of cases ≥ arithmetic mean or median, R = number of runs, and p = exact two-tailed probability value. Samples: DP = dental patients with periodontitis, MHP = mental health patients with depressive symptomatology, and Pooled sample = union of two patient samples. Variables: SSES = subjective socioeconomic status, BDI-II = total score in the Beck Depression Inventory-II, OHHS= total score in the Oral Hygiene Habits Scale, OHIP-14-PD = total score in the Oral Health Impact Profile applied to Periodontal Disease, CAL = clinical attachment loss, IL-1β = salivary interleukin 1 beta concentration, IL-6 = salivary interleukin 6 concentration, and MMP-8 = salivary matrix metalloproteinase-8 concentration.
