Effect of an instructional motivation program on oral health in Danish adolescents after 1 and 2 years.

A 2-year study of the isolated effect of an intensive motivation program in the oral health of 11--15-year-old schoolchildren was carried out in a Danish provincial town. The motivation program consisted of small-group sessions during which maximum effort was made to obtain active engagement from the children. After 1 year the experimental group was supplemented with two new groups of children who in addition to the motivation participated in a competition on dental hygiene. The effect of the motivational program on knowledge and behavior was evaluated. While the program seemed to result in a reinforcement of the already existing positive attitude, the cognitive level was only slightly improved and no change in behavior resulting in improved oral health was registered.
