title: [Studies of the effectiveness of impersonal teaching by means of a sound film: "Conduction anesthesia on the mandible"].
abstract: The thesis that students could be instructed by audio-visual aids alone equally as well as by a personal instructor was tested by experiment. A teaching program, i.e. a sound film, was made and was shown to first-year clinical dental students. At the same time the usual lecture was offered to these students. Subsequently the knowledge acquired was examined. The results support the initial thesis, but at the same time it must be concluded that the highly differentiated psychomotor teaching objectives of dentistry cannot be achieved without individual instruction.
