Typodont versus live patient: predicting dental students' clinical performance

Area of Science:

• Dental Education
• Prosthodontics
• Clinical Skills Assessment

Background:

• Evaluating dental students' preclinical skills is crucial for patient safety.
• Manikin-mounted typodonts are commonly used for non-clinical skills assessment.
• Predicting clinical performance from typodont proficiency requires validation.

Purpose of the Study:

• To assess the accuracy and precision of typodont-based crown preparation evaluation.
• To determine if typodont performance predicts clinical performance on patients.
• To analyze agreement between non-clinical and clinical crown preparation assessments.

Main Methods:

• Eighty-six dental seniors' crown preparations were evaluated on typodonts and patients.
• Three calibrated faculty members assessed four key preparation areas.
• Kappa agreement statistic and Bland-Altman plots analyzed performance data.

Main Results:

• Weak agreement was found between typodont and patient crown preparation assessments.
• Significant variation in performance differences was observed.
• Students generally performed worse on patient examinations than on typodonts.

Conclusions:

• Typodont-based crown preparation assessment is a poor predictor of clinical patient performance.
• Current non-clinical evaluations may not accurately reflect students' real-world clinical abilities.
• Further refinement of preclinical assessment methods is needed.
