Evaluation of predictor variables for a self-instructional preclinical course

Several studies have shown that the Dental Admission Test and predental grade point average have validity in predicting performance in dental school. The purpose of this two-year study is to compare these predictors with a manual skill exercise to determine their usefulness in predicting manual dexterity success in operative dentistry. Sophomore students were instructed to make preparations on an Ivorine block following imprinted outlines. Correlation to performance on laboratory examinations was computed. Results indicate the traditional predictors have limited usefulness in manual skill prediction while the Ivorine block exercise demonstrated consistent correlation over both years. The emphasis on manual dexterity in preclinical dental courses requires that appropriate variables be used in selecting students.
