Summary
This study developed rating criteria for digital wax-up performance in dental students. The criteria demonstrated high reliability, but volumetric discrepancy did not correlate with qualitative scores.
Area of Science:
- Dental Education
- Digital Dentistry
- Computer-Aided Design (CAD)
Background:
- Digital wax-up is a key preclinical skill in modern dentistry.
- Evaluating student proficiency in CAD-based digital wax-up requires reliable assessment tools.
Purpose of the Study:
- To introduce and evaluate the reliability of new rating criteria for a digital wax-up preclinical program.
- To assess the internal consistency and inter-rater reliability of the developed rating system.
Main Methods:
- 47 dental students performed digital wax-ups using CAD software.
- Two instructors evaluated student work using seven qualitative criteria.
- Inter-rater reliability was assessed using weighted kappa; volumetric discrepancy was measured.
Main Results:
- The seven qualitative criteria showed high inter-rater reliability (kappa values 0.62-0.93).
- A negative correlation between qualitative scores and volumetric discrepancy was observed but not statistically significant (ρ = -0.27, P = .09).
Conclusions:
- The developed qualitative criteria are reliable for evaluating student digital wax-up performance.
- Digitally measured volumetric discrepancy alone is insufficient to predict overall qualitative performance in digital wax-up.
