A two group time series design was used to determine if exposure of adolescent clients to dental plaque charts during oral health instruction sessions is effective in motivating them to improve oral health over a six month period. Fifty-six adolescents who previously had received treatment at Old Dominion University Dental Hygiene Clinic consented to participate and were randomly assigned to a control or experimental group. Both groups of adolescents received identical oral health instructions from a research assistant; the experimental group's oral health instruction included an additional discussion about the dental plaque chart. The Patient Hygiene Performance Index and the Gingival Bleeding Index were used to measure oral hygiene and oral health status resulting from the adolescent's motivation to perform plaque control procedures. Results indicate that the dental plaque chart was ineffective in motivating adolescent clients to brush and floss their teeth over six months. Additionally, the results did not support the existence of a strong relationship between oral hygiene and oral health status.
