ABSTRACT Purpose: to verify the effects of tongue pressure exercises against the incisive papilla, used both alone and in combination with functional swallowing training, on the electrical activity of the suprahyoid muscles and the self-perception of aesthetic changes in the submandibular region. Chi-square, Fisher’s exact, Mann-Whitney, Kruskal Wallis, and Wilcoxon tests were used. The significance level was set at 5%. Methods: an experimental, analytical, prospective study on 27 women, aged 30 to 78 years, divided into two treatment groups (G1 and G2), and a control group (CG). Individuals were submitted to 8 weeks of training, in which G1 performed only tongue pressure exercises against the incisive papilla, and G2 performed the same exercises in combination with swallowing training, while CG was not submitted to any intervention. The suprahyoid muscle electrical activity was obtained with surface electromyography at the beginning and end of the study when subjects also answered a self-perception questionnaire on possible aesthetic results. Pearson’s chi-square, Fisher’s exact, Mann-Whitney, Kruskal Wallis, and Wilcoxon tests were used. The significance level was set at 5%. Results: statistically significant differences were found between the initial and final electrical activity in both G1 and G2, which was not found in CG. There was no significant difference between the groups regarding their self-perception of visual or muscle improvements. Conclusion: both strategies analyzed were equally effective to increase suprahyoid muscle recruitment, though with no impact on the self-perception of aesthetic changes in the submandibular region.
