Purpose:
To present the measures for tongue pressure in Brazilian young adults, considering specific tasks, and to verify the differences regarding gender and according to the tasks.
Methods:
Fifty-one volunteers aged 18 to 28 years, of both genders with normal occlusion and without speech disorders were evaluated. We used the Iowa Oral Performance Instrument in the evaluation of tongue pressure (kilopascal) during specific tests of elevation, protrusion, swallowing, and lateralization, in addition to the endurance test (seconds). The analysis was conducted using analysis of variance, followed by the Tukey's multiple comparison test, adopting a 5% significance level.
Results:
The values obtained for men and women in the tests were as follows: elevation, 63.94±12.92 and 50.27±15.29; protrusion, 60.22±13.62 and 44.30±12.95; swallowing, 33.94±12.06 and 34.27±13.25; lateralization on the right, 44.15±10.47 and 31.85±8.46; lateralization on the left, 43.15±10.22 and 29.55±8.91; and endurance test: 24.85±10.95 and 17.35±6.71, respectively. The values were higher in men compared with women for the protrusion and lateralization tasks. The measures of the protrusion and elevation tasks did not differ for men but were higher in both genders than those of the lateralization and the swallowing tests. There was no difference in lateralization according to side in both the genders.
Conclusion:
The measures for the tongue pressure in Brazilian young adults were determined by specific tasks. Gender influenced the pressure of the tongue values for the protrusion and lateralization tasks. Elevation and protrusion tasks measures were higher than those of the lateralization and swallowing tasks.
