This study was conducted in 3 different experimental conditions. The first experiment compared TongueFit and the standard manometer using a force tester (MCT-2150), with pressure controlled by MSatLite software. The second and third experiments involved 2-cm and 3-cm bulbs between the 2 devices. This study used Lin concordance correlation to measure the level of agreement.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec sec-type=\"results\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>There was a mean absolute difference of 0.005 kilopascals (kPa) between the TongueFit and the standard manometer (n=35, \u03c1C=1). Statistical analysis showed perfect agreement correlation (\u03c1C=1). By using the 2-cm bulb, TongueFit\u2019s mean was 0.007 kPa lower, also showing perfect agreement (\u03c1C=1). Furthermore, using the 3-cm bulb, results showed almost perfect agreement (\u03c1C=0.999) with the TongueFit\u2019s mean, which was 0.044 kPa lower.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec sec-type=\"conclusions\">\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This study confirms the high validity of TongueFit as an orofacial manometer compared with a standard manometer, with negligible mean differences, as well as near-perfect and perfect agreement in the experiments.
