Overview

Cross-sectional study evaluates the impact of self-perceived malocclusion on quality of life among Nigerian adolescents, suggesting early intervention may be beneficial.

Key Points

  • To evaluate the psychosocial impact of self-perceived malocclusion on oral health-related quality of life in Nigerian adolescents and young adults.
  • Cross-sectional study including 316 participants aged 13-25 years from secondary schools and a university in Kano State.
  • Data collected via self-administered questionnaires: IOTN-AC, PIDAQ, and OHIP-14.
  • Statistical analysis included descriptive statistics, Wilcoxon tests, chi-squared tests, Spearman correlations, and multivariable logistic regression.
  • 63.3% of participants reported high psychosocial impact (PIDAQ > 31).
  • 32.9% experienced negative OHRQoL (OHIP-14 > 14).
  • Male sex (OR = 2.65, 95% CI: 1.48–4.83) and higher IOTN-AC score (OR = 1.30, 95% CI: 1.12–1.53) were significant predictors of high psychosocial impact.
