Rationale: Orthodontic treatment is usually initiated during adolescence period. This period has physiological and psychological changes associated with increasing nutritional needs. After orthodontic treatment, individuals avoid to consume some of hard food, particularly fruits, raw vegetables because of chewing problems. Because of orthodontic treatment, eating behavior of the patients usually alters and some of the macro and micronutrients’ intake may be inadequate. The aim of this study was to examine effect of orthodontic treatment on nutrient intakes of adolescents.
Methods: This study was carried out in Hacettepe University Department of Orthodontics on 17 adolescents (mean age: 13,76±2,01) orthodontic patients. Socio-demographic and food frequency questionnaires and 24- hour dietary recall were held initially. Dietitians interviewed face to face to
held a questionnaire which included some of questions about dietary changes 24-hour dietary recall each time of the end of the first week, the first month and the third month of the orthodontic treatment.
Results: The findings show no significant different intake of total calories, protein, carbohydrate and fat among four interview in adolescents (p>0.05) during the follow-up for 3 months. The intake of vitamin C (p=0,003), vitamin B12 (p=0,015), potassium (p=0,02) and phosphor (p=0,026) was significantly lower at the end of orthodontic treatment. The intake of calcium, fiber and other macro- and micro-nutrients did not differ significantly among interview (p>0,05).
Conclusions: Orthodontic treatment can cause detrimental changes in dietary intake of adolescents. Since the critical stage of development, adolescents should be directed to dietitians for consultancy.
