摘要：OBJECTIVE: The aim was to assess factors which may contribute to the diet quality of adolescents with orthodontic malocclusion. MATERIALS and METHOD: Demographic and dietary data of 46 girls and 30 boys (mean age 11.4 ± 1.4 years), with good oral and systemic health were obtained. Data were evaluated in relation to skeletal growth pattern, malocclusion, overjet, overbite, number of posterior functional tooth units (PFTU) and parental education level. Dietary intake was measured by using 24-hour dietary recall method, and diet quality was assessed by using the Healthy Eating Index-2010 (HEI-2010). Energy and nutrient intake was calculated by using the Nutrition Information System (BeBiS) program. Intergroup comparisons were performed by using Mann-Whitney U and Kruskal-Wallis tests. RESULTS: Maternal education level affected the total HEI (p = 0.002), total fruit (p = 0.007), whole fruit (p = 0.018) and refined grains (p = 0.044) scores. Skeletal growth patterns, malocclusions, overjet and overbite did not alter the diet quality. Overbite was positively correlated with energy (r = 0.297, p = 0.009), carbohydrate (r = 0.238, p = 0.039) and protein (r = 0.305, p = 0.007) intake. Overjet was positively correlated with greens and beans scores (r = 0.238, p = 0.038). PFTU was positively correlated with the body mass index (r = 0.327, p = 0.004). CONCLUSION: From a clinical perspective, malocclusion may not have a significant impact on the nutritional habits of adolescents. Maternal educational level, however, was found to be the main determinant for the diet quality during adolescence.
