[Report on the learning effect in school children following toothbrushing instruction by students].

After they had gone through a training program on the prevention of caries and periodontal disease, 20 students instructed young patients in how to brush their teeth. One of the students instructed a class of 35 pupils. The change-over from the learning situation to the situation at the patient was successful with 77% of the students. Questionnaires filled out by the patients before and after the instruction reveal that specific information and motivation regarding improved personal oral hygiene had increased.
