Dental students' self-evaluation comparison between dual dental education systems in Korea

This study aimed to examine the satisfaction, educational linkage, and self-perceived competence of dental students enrolled in either 4 + 4 dental program, comprising an undergraduate degree and Doctor of Dental Surgery degree (DDS), or 3 + 4 program, which is a BS/DDS combined degree program, in the Korean dental education system.

The survey questionnaire using a 5-point Likert scale was developed and validated by four dental education experts, consisting of satisfaction with undergraduate courses, the interconnection of undergraduate courses with the DDS curriculum, and self-assessed core competency for dental graduates. A total of 252 students provided informed consent and voluntarily responded to the survey, among whom 109 students were in the 3 + 4 system and 143 were in the 4 + 4 system. Cronbach's correlation analysis and independent t-test were conducted for each evaluation item.

Students' overall satisfaction level with the undergraduate education was higher in the 4 + 4 system than in the 3 + 4 system (P = 0.003). Students enrolled in the 4 + 4 system recognized that natural sciences are more connected to the graduate-level DDS program (P <  0.001), while the 3 + 4 students recognized that studies in medicine are closely interconnected to the DDS program (P = 0.001). There was almost no statistically significant difference in the students' perception of competency between the two education systems.

Even though this study analyzed the case of a single university operating both 3 + 4 and 4 + 4 systems, it can be used as the groundwork for developing new opportunities and models of dental education system.
