Purpose: To identify the relationship between periodontal health knowledge and oral health-related quality of life among Caribbean adults.
Materials and Methods: A cross-sectional study was conducted in a representative sample from 3 Caribbean cities (weighted N = 1805). Participants completed a questionnaire on oral health knowledge, hygiene habits, and other practices, as well as the Oral Health Impact Profile-14 (OHIP-14) questionnaire. The associations between knowledge and habits and OHIP-14 score and its tertiles were evaluated using negative binomial and multinomial logistic regression models, respectively, adjusting for confounders. Odds ratios and regression coefficients were reported.
Results: Participants reporting none, little, and adequate knowledge about gum health had higher odds of being in the worst tertile for OHRQoL, compared to those reporting “good knowledge” (ORnone vs good = 2.38, 95% CI: 1.59–3.54; ORlittle vs good = 1.82, 95% CI: 1.19–2.78; ORadequate vs good = 1.68, 95% CI: 1.11–2.57). Participants reporting toothbrushing ≥ twice/day were less likely to be in the worst tertile for OHRQoL, compared to those brushing less often (OR = 0.67, 95% CI: 0.48–0.92). Self-reported gum bleeding was associated with double the odds of being in the worse tertile (OR = 2.03, 95% CI: 1.60–2.58).
Conclusion: According to the findings of this study, periodontal health knowledge is associated with reduced OHRQoL in Caribbean Adults. In addition, the frequency of brushing and the self-reported gum bleeding was related to a worse quality of life (QoL) level.
