Glucose concentration was measured after 5\u2010, 10\u2010, and 15\u2010s mastication of gummy jelly and compared to Hue values obtained from the color\u2010changing gum method (reference method). In addition, all participants were asked to fill out the Oral Health Impact Profile questionnaire (OHIP) to assess differences in perception related to the mouth before and after the placement of braces.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Glucose concentrations were strongly correlated to measures of the two\u2010color chewing gum methods (\n                      <jats:italic>R<\/jats:italic>\n                      <jats:sup>2<\/jats:sup>\n                      \u00a0=\u00a00.965).
