This study aimed to develop, implement, evaluate and validate a blended learning head and neck ultrasound (HNUS) curriculum for dental students, guided by the ICAP (Interactive, Constructive, Active, Passive) framework and Kirkpatrick\u2019s evaluation model.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Material and methods<\/jats:title>\n                    <jats:p>Following Kern\u2019s six-step approach to curriculum development, a prospective quasi-experimental design was applied. Dental students (study group) completed the curriculum and were assessed at three time points (T1: pre-course; T2: Immediate post-course; T3: three-month follow-up). Physicians with prior certified ultrasound training served as a reference group at T2. The intervention combined video-based e-learning modules, lecture notes, anatomy posters, and peer-assisted hands-on training. Primary outcomes were objective knowledge (theory test at T1-T3) and practical performance (Direct Observation of Procedural Skills\u2009=\u2009DOPS at T2). Secondary outcomes included self-assessed competence, satisfaction, and attitudes toward ultrasound education (7-point Likert scale).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 64 students completed T1\u2013T2, and 21 completed T3 three months after course completion. At T2, students demonstrated significant gains in theoretical knowledge compared to T1 (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001, d = \u2212\u20094.1). Although a moderate decline was observed at T3, scores remained substantially above T1 (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001). In the direct comparison at T2, physicians achieved significantly higher theory test scores than students (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.011). While overall DOPS performance did not differ significantly between students and physicians (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.59), domain-specific variations were observed. Self-assessed competencies increased markedly from T1 to T2 (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.0001), with sustained improvements observed at the three-month follow-up (T3) in the subgroup of participants who completed all assessments Evaluation of curricular components yielded consistently high ratings (mean 6.1\u20136.5\/7), with e-learning and hands-on stations most valued. Students strongly endorsed the integration of ultrasonography into dental curricula and favoured blended learning approaches.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This study provides initial evidence that a structured, ICAP-informed, and Kern\u2019s six-step\u2013guided blended HNUS curriculum for dental students is feasible, effective, and well accepted.
