Hypothetical model estimated from the pooled sample of 58 dental and mental health patients. Estimation method: Maximum likelihood. Average variance extracted (AVE) = 0.467 and McDonald’s coefficient ω = 0.721 for the measurement model. Probability value under condition of the null hypothesis was true (H0: β = 0) at a two-tailed test: --- p > 0.05, * p ≤ 0.05, p ≤ 0.01, *** p ≤ 0.001. ln(IL-1β) = Napierian logarithm of salivary interleukin 1 beta concentration, ln(IL-6) = Napierian logarithm of salivary interleukin 6 concentration, ln(MMP-8) = Napierian logarithm of salivary matrix metalloproteinase-8 concentration, and e = measurement or structural error.
