Hubungan Indeks Massa Tubuh dan Maloklusi Skeletal Pasien Ortodontik Dewasa

Abstract

The demand for orthodontic treatment among adult patients has increased in recent years. Among the various risk factors and success factors for orthodontic treatment, dietary patterns related to nutritional status have an impact on the mechanical and cellular response to tooth movement. Therefore, this study aims to analyze the relationship between body mass index and skeletal malocclusion in adult orthodontic patients treated at USU Dental Hospital. This is an analytical study with a cross-sectional design. This study was conducted on 81 samples, with height and weight measurements using Maloklustab to obtain body mass index values. Meanwhile, the maxillary-mandibular relationship values in the sagittal direction were taken from secondary data in the patients' medical records. After analysis using the Chi-Square test and obtaining an expected count < 5 of more than 20%, the p-value was selected based on Fischer's Exact test. The results of this study showed no significant relationship between BMI and the SNA angle (p = 0.213), BMI and the SNB angle (p = 0.397), and BMI and skeletal malocclusion as assessed by the ANB angle (p = 0.510). In conclusion, BMI variation has no significant relationship with skeletal malocclusion. However, further research on BMI and bone remodeling processes in the adult population is needed.
