The Effectiveness of Oral hygiene instruction by Roleplay on dental plaque control among primary school students

Abstract

          This study was a quasi-experimental research which aimed to study the effectiveness of oral hygiene instruction by role-play on dental plaque control among primary school students (grade 4-6) in Makhamlom subdistrict, Bangplama district, Suphanburi province. Cluster Random Sampling was constructed to select from 2 schools with the same qualifications as an experimental group of 41 people and a control group of 45 people. The experiment group had oral hygiene instruction by role-play activities. The control group had regular oral hygiene instruction. The researcher collected data before and after the interventions by using questionnaires and evaluation forms of dental plaque level. Data were analyzed using percentage, mean, standard deviation, paired t-test, and independent t-test. The results of the study were as follows: within the group, the experimental group had a higher score of knowledge of dental health care and less amount of dental plaque after receiving the interventions (p<0.05).  When compared between 2 groups after receiving the interventions, there was no difference between the experimental group and the control group on  knowledge of dental health care and the amount of dental plaque.
