ABSTRACT
ABSTRACT Purpose:
to analyze the electromyographic activity of the suprahyoid muscles during deglutition in participants with Angle´s Class II malocclusion.Methods:
electromyographic data recordings were performed in the supra-hyoid muscles during swallowing and at rest, in 30 volunteers, 15 Angle´s Class I participants and 15 Angle´s Class II malocclusion, aged 15-27 years old. The Root Means Square values for both tests were analyzed, and for the deglutition test, the Linear Envelope was used to observe the type of muscle activation pattern.Results:
during the test at rest, there was no significant difference in Root Means Square values (p=0.22) between Class I and Class II subjects. During deglutition, it was found that Angle´s Class II subjects had significantly higher RMS values (p=0.01) as compared to Class I volunteers. Regarding the type of muscle activation pattern, there was a significant difference between Class I and Class II participants with a predominance of type 1 peak for Class I and type 2 peak for Class II.Conclusion:
there was a difference in electromyographic recordings during deglutition in participants with Angle´s Class II as compared to Class I participants with a tendency towards two contraction peaks, showing a greater imbalance during the function. There was no difference between groups in the rest position.
