BMI in orthodontics

We studied the changes in Body mass index during the first year of orthodontic treatment. we recorded and analyzed the BMI of participants from T0 to T5 over 12 months during orthodontic treatment. The data collected were height in centimeters to the nearest 0.5 cm, measured with an audiometer (Seca 217, CA 91710, Chino, USA), and weight in kilograms to the nearest 0.5 kg, measured with a weighing machine (Seca 813, CA 91710, Chino, USA). Repeated measures ANOVA followed by Tukey's HSD post-hoc test was used to assess the significant differences at the indicated time intervals (T0, T1, T2, T3, T4, and T5). T0, T1, T2, T3, T4, and T5 indicate the start, and the end of the first, second, third, sixth, and twelfth months, respectively.
results:BMI gradually decreased in females from T0 to T4 and increased from T4 to T5. BMI in males did not differ drastically from T0 and returned to the initial values at the end of study period. BMI changes in males were minimal, and no significant changes were observed from T0 to T4 and T5,.The changes in BMI were relatively greater in females. Females showed a sharp dip in the graph, whereas males showed gradual changes. However, both values returned closer to their initial values at the end of the study period. conclusion: Hence, changes in BMI during orthodontic treatment can be considered temporary and to have no significant overall impact at the end of 1 year.
