Note. Samples: DPS = sample of dental patients with periodontitis, MHS = sample of mental health patients with depressive symptomatology, and GPS = general population sample. Statistics: n₀ = number of cases < arithmetic mean, n₁ = number of cases ≥ arithmetic mean, R = number of runs, and value = two-tailed exact probability value. Variables: BDI-i = item i (1 to 21) of the Beck Depression Inventory-II, BDI-II = BDI-II total score, OHHS-i = item i (1 to 8) of the Oral Hygiene Habits Scale, OHHS = OHHS total score, CAL = clinical attachment loss, and PI = plaque index.
