Abstract: Pediatric dentistry is a highly practical and hands-on discipline, requiring pediatric dentists to possess comprehensive decision-making abilities and strong doctor-patient communication skills in clinical practice. The quality of internship courses directly determines the training quality of pediatric dental professionals as they transition from medical students to practitioners, influencing whether students will continue to work as pediatric dentists after undergraduate graduation or choose to pursue postgraduate studies in pediatric dentistry. Through the reform and optimization of the internship teaching mode for three consecutive years, the research group led students to carry out teaching activities according to the teaching objectives in the four stages of pre-internship, mid-internship, post-internship and final stage. Students selected personalized clinical cases and embedded them into the case-based learning (CBL)+Seminar teaching mode for discussion. Through the analysis of three dimensions, namely, students' assessment results, students' satisfaction with the teaching program and patients' satisfaction with the students, it was concluded that CBL+Seminar teaching method based on children's oral checklists can strengthen and improve students' internship effect and enhance students' sense of identity with children's stomatology, so as to cultivate high-quality children's stomatologists to meet the urgent needs of society.

Key words: pediatric dentistry, case-based learning, Seminar teaching, undergraduate students, internship effectiveness
