The effect of a cognitive behavioral intervention on oral hygiene.

Several medical areas that require patient compliance have successfully used psychological interventions emphasizing cognitive behavioral components. However, there are no published reports on the effect of cognitive behavioral interventions on oral hygiene in adults using an experimental design. For this study, 100 male veterans age 21-65 years were randomly assigned to 4 groups (cognitive behavioral, education, attention control, and control); to compare the effectiveness of these interventions on oral hygiene, a 5-week pre-test-post-test design was utilized. The dependent variables were self-report of brushing and flossing behavior and dental plaque levels utilizing the plaque index. After the interventions, there was only one significant difference between the control and the experimental groups for brushing frequency. There were no significant differences among the experimental groups for this intervention. The self-report of flossing frequency significantly increased in all 3 treatment groups, but there were no significant differences between these groups. In addition, plaque levels decreased significantly in all 3 experimental groups. Plaque levels in the cognitive behavioral group were significantly lower than those of the educational group. It was not possible to determine whether the greater plaque reduction in the cognitive-behavioral group could be attributed to the nature of the intervention or to the extra time spent with patients in the cognitive behavioral group.
