Abstrakt: Objectives: Perceptual ability test (PAT) is a valid determinant for spatial perceptions. However, proven psychomotor skill tests for dentistry do not currently exist. This study aimed to determine whether performance on the PAT, Operation game, mirror tracing, and wax carving exercises correlate to preclinical laboratory performance in Dental Anatomy and Restorative Dentistry courses.
Methods: First-year dental students (n = 96) participated in the study. Final laboratory grades were obtained from course directors of preclinical Restorative Dentistry and Dental Anatomy courses. Admissions committee provided participants' PAT results. Participants completed a wax carving exercise by carving a cube and a semicircle into a wax block using the wax subtraction method. Two calibrated faculty graded the carvings as Ideal (5), Satisfactory (3), or Unsatisfactory (1). Time to complete the Operation game and number of infractions were recorded. Participants traced the six-pointed star pattern on the Auto Scoring Mirror Tracer instrument in both clockwise and counterclockwise directions. Completion times and number of instances outside the pattern were recorded. Spearman Rank Correlations were used to determine associations at 0.05 confidence interval.
Results: Mean PAT score was 21.7; mean times to complete the Operation game and mirror tracing exercise were 4:20 and 1:30, respectively. Mean score on the wax carving exercise was 3.19. Correlations between the independent and dependent variables were minimal to weak. The wax carving exercise was the most reliable predictor of performance.
Conclusions: When PAT scores are striated into low (less than 20), middle (21-22), and high (23-30), it was possible to predict performance in both preclinical laboratory courses.
