Alterations of oral functions and dental malocclusions in adolescents: a cross-sectional population-based study

Abstract This article aims to assess whether alterations of oral functions (AOF) are associated with malocclusion (MO)’s type and severity. Cross-sectional study of a representative sample of 332 adolescents aged 12 years in São Luís-MA, Northeastern Brazil. MO criteria included Angle’s classification, Dental Aesthetic Index, and other morphological problems. The AOF were evaluated by breathing, phonation, chewing, and swallowing. Odds ratios (OR) and 95% confidence intervals (95%CI) were calculated using logistic and multinomial regression analyses (α=5%). Mouth breathing was associated with defined (OR=3.84; 95%CI=1.45-10.12), disabling (OR=4.34; 95%CI=1.99-9.49), and class III (OR=4.15; 95%CI=1.19-14.54) MO. Phonation problems were associated with defined (OR=2.01; 95%CI=1.02-4.39), disabling (OR=3.04; 95%CI=1.55-5.96), and Class II (OR=2.02; 95%CI=1.28-3.18) MO. Chewing disorders were associated with posterior crossbite (PCB) (OR=2.32; 95%CI=1.12-4.82). Swallowing disorders were associated with Class III MO (OR=5.66; 95%CI=1.35-23.71), PCB (OR=6.13; 95%CI=2.76-13.62), and posterior open bite (OR=4.53; 95%CI=1.72-8.92). Breathing and phonation alterations are associated with MO in anterior arch segments, while chewing and swallowing disorders, in the posterior segments.
