Parents frequently represent the first point of contact following injury. Although the ToothSOS mobile application (App) is based on current guidelines of the International Association of Dental Traumatology, evidence integrating usability assessment using validated instruments with longitudinal knowledge retention in parental populations remains limited. This study evaluated the usability of the ToothSOS App using the validated System Usability Scale (SUS) and examined parental knowledge gain and retention over time.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods<\/jats:title>\n                    <jats:p>In this prospective longitudinal questionnaire\u2010based study, parents were assessed at baseline (T0), immediately after application use (T1), and one month later (T2). Knowledge of fracture and avulsion management was measured using standardized true\u2013false items. Perceived usability, the primary outcome, was assessed using the SUS. Nonparametric repeated\u2010measures analyses were performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 149 parents completed all assessments. The ToothSOS App demonstrated high perceived usability, with a mean SUS score of 78.4\u2009\u00b1\u20098.3, exceeding the established benchmark for above\u2010average usability. Knowledge scores differed significantly across time points (Friedman\n                      <jats:italic>\u03c7<\/jats:italic>\n                      <jats:sup>2<\/jats:sup>\n                      \u2009=\u2009187.920,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001), increasing from a median of 5 (IQR: 2) at baseline to 9 (IQR: 2) at T1 and remaining elevated at 8 (IQR: 3) at one month.
