Two dental courses teaching computer-aided all-ceramic restorations were compared. The problem-based learning (PBL) HYBRID course improved student-teacher relations but led to less satisfaction with personal success compared to the traditional TRAD course.

Area of Science:

  • Dental Education
  • Computer-Aided Technology in Dentistry

Background:

  • Dental students require training in computer-aided all-ceramic restorations.
  • Comparing traditional and innovative teaching methods is crucial for optimizing dental education.

Purpose of the Study:

  • To compare a traditional teacher-centered (TRAD) course with a problem-based learning (PBL) HYBRID course.
  • To evaluate student and evaluator perceptions of two distinct educational approaches using identical computer software.

Main Methods:

  • Undergraduate dental students were randomly assigned to TRAD or HYBRID courses.
  • Student satisfaction and learning conditions were assessed using a Likert scale.
  • Practical work was evaluated by independent assessors; statistical analysis used the Mann-Whitney U-test.

Main Results:

  • Both courses were perceived as demanding.
  • The HYBRID group reported significantly better course atmosphere and student-teacher relationships.
  • No significant differences were found in the practical outcomes between the TRAD and HYBRID groups.
  • The HYBRID group reported lower satisfaction with their own success despite better learning conditions.

Conclusions:

  • The HYBRID (PBL) approach enhanced the learning environment but may increase self-skepticism or perceived burden due to intellectual demands.
  • While learning conditions improved, students in the HYBRID course showed less confidence in their achievements.
  • Further research is needed to understand the impact of PBL on student self-perception and overall satisfaction in dental technology training.
