Abstract:

Objective: To assess whether alterations of oral functions (AOF) are associated with malocclusion (MO)’s type and severity. Methods: 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%). Results: 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 classe 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). Conclusions: Breathing and phonation alterations are associated with MO in anterior arch segments, while chewing and swallowing disorders, in the posterior segments. The strength of associations is higher in more severe MO.
