Objective: The aim of this study was to evaluate the effect of the dental plaque control by self-regulation learning in elementary school children classified into groups according to caries risk level.
Methods: Students (n=170) and their parents filled out questionnaires on behavior and attitude to oral health care. We conducted an oral examination of children including tooth and plaque status and calculated DFT index and plaque control rate (PCR) which is the value obtained by subtracting O’leary index from 100%. Then we classified group by caries risk level according to caries risk assessment. We showed students their PCR and plaque disclosing image and they set up their own goals of PCR individually using a self-regulation learning. three months later, we conducted questionnaires and PCR again and compared the first outcome with the second.
Results: There was no distinct variation on oral health life during the test period (p>0.05). The score of dental plaque has more high risk group than moderate group (p<0.05). But lower group were more increased than plaque score of upper group of self-regulation learning.
Conclusion: A self-regulation learning of dental plaque control has effective set of a oral health education with caries risk assessment for children.
