Objective　To investigate the construction process and application effect of teaching resources database for orthodontics. Methods　A questionnaire survey was performed among 40 students and 8 teachers in Department of Stomatology Affiliated Hospital of Inner Mongolia Medical University to investigate the need for the construction of teaching resources database. A total of 60 undergraduates who did not enter clinical practice were selected and randomly divided into experimental group and control group

with 30 students in each group

and theoretical teaching and assessment of special topics were performed. The independent samples t-test was used to compare examination results between the two groups and evaluate the application effect of teaching resources database. After 2 weeks of theoretical teaching

30 students in the experimental group were surveyed for their satisfaction with the teaching resources database. Results　The results of the questionnaire survey on the need for resources database construction showed that all teachers and students wanted to use the resources database in teaching; the students needed the examination database and the case library the most

while the teachers needed the courseware database the most. Of all teachers and students

61.7% hoped to obtain resources through fixed website platforms

and 93% of the students and 87.5% of the teachers expressed their interests in online interaction. The satisfaction analysis of the teaching resources database showed that more than 90% of the students were satisfied with the practicability

high efficiency

and vividness of the teaching resources database

and 76.7% of the students were satisfied with the authority and comprehensiveness of the database. As for the application effect of the teaching resources database

the experimental group had significantly higher examination scores than the control group (P<0.05). Conclusion　The teaching resources database for orthodontics should be constructed based on the needs of teachers and students and the teaching syllabus. Teaching resources should be collected comprehensively

the evaluation system should be improved and optimized

and development and utilization of the database should be performed with the help of network platforms.
