Abstract

Objectives: Rumination is a maladaptive emotion regulation strategy. It has been associated with several psychological disorders and physical problems. This cross-sectional study aimed to evaluate whether cognitive rumination is associated with periodontal disease (PD), tooth loss (TL), and oral health-related quality of life (OHRQoL).

Materials and methods: A population-based sample from a rural area in southern Brazil was evaluated. Calibrated examiners carried out a complete periodontal examination at six sites-per-tooth. Rumination and Reflection (RRQ) and Oral Health Impact Profile (OHIP-14) questionnaires were administered. Regression modeling was used to assess the prevalence ratio (PR) between rumination and PD and to estimate the rate ratio (RR) between rumination and TL and rumination and OHIP.

Results: Severe periodontitis prevalence of 33% was observed in the sample. In the Poisson-adjusted model (n = 587), individuals who ruminate more have 27% more periodontal disease (PR: 1.27, 95%CI:1.02 - 1.60). Regarding TL and OHIP, negative binomial regression (n = 672) showed an association with rumination, but it was not significant (RR 1.14, 95%CI 0.99 - 1.31) and (RR 1.20, 95%CI 0.98 - 1.48), respectively.

Conclusions: Cognitive rumination was independently associated with periodontal disease in individuals living in a rural area. Borderline non-significant estimates were observed regarding TL and OHRQoL. More research using different populations and focusing on individual's responses to psychological stress may confirm these results.

Clinical relevance: Emotional regulation is crucial to deal with stress, anxiety, and depression. Since psychopathologies are among the most prevalent diseases in the world, it is critical to understand the role of these issues in dental outcomes.
