Masticatory function according to body mass index. Part II: electromyographic analysis

Introduction: The objective of this study was to explore the electrical activity superficial muscles mastication required exert unilateral maximum bite force in subjects with different body mass index. Material and Methods: A cross-sectional observational conducted a sample 21 participants an average age 22.9 ± 3.5 years who were classified according their index, forming three groups: normal weight (18.5-24.9), overweight (25-29.9) obesity (≥30), seven each. Through surface electromyography, during right left evaluated. Results: No statistically significant differences observed between groups. data obtained from electromyographic analysis demonstrate trend indicating that index similarly activate on each side when performing particular side, while or obese demonstrated significantly greater activation temporalis muscle associated where maximal is performed. Conclusion: Our findings suggest not influenced by performance increased present
