Student performance was compared on written and psychomotor skill tests of freshman dental students receiving conventional lectures versus the same lectures containing interactive components using TurningPoint, a wireless audience response system (ARS). The research design was a controlled crossover study with seventy-seven freshman dental students conducted in a preclinical operative dentistry course. Two randomized groups alternated the two study lectures, one with ARS and the other without ARS. Student knowledge retention was measured through written examination using immediate posttest, as well as questions on the unit and final examinations. Psychomotor skill tests were given on both lecture topics. Statistically significant differences indicating superiority of ARS were identified for performance on the immediate posttest and psychomotor skill test only for the lecture "Principles of Dental Bonding." The other examinations/skill testing showed no significant difference. These results indicate that ARS is a promising teaching tool for dental education.
