Behavioral dentistry: a multiple-baseline study incorporating contracting with patients

The present investigation examined the effects of contracting upon modification of oral hygiene skill and plaque indexes. Three males and one female from a VA domiciliary attended 20 oral hygiene patient-education classes during which personalized flossing and brushing instructions were given. Double-blind personal contracting procedures were applied within a multiple-baseline design across subjects and behaviors. Responses indicated that signing either the skill or plaque contract modified the related index in the desired direction. Contracting appears a viable strategy for selected oral hygiene problems.
