Dental plaque, Oral hygiene, Young children, Caregivers


The objective of the analytical cross-sectional study was to examine the factors related to the oral hygiene of young children in 6 southern provinces of Thailand. The participants included 745 young children aged 6 months to 2 years and their caregivers who attended the hospitals for vaccination and health examination for their children. Dental plaque was assessed based on Rustogi Modified Navy Plaque Index. Demographic data, knowledge, and practices in oral health care for children and perceptions of oral health care based on the Protection-motivation theory of caregivers were interviewed through a structured questionnaire. Descriptive statistics and multiple logistic regression statistics were used in data analysis. The study revealed that there were 67 % of young children had high dental plaque levels. From multiple logistic regression analysis, the frequency of tooth brushing for children and the knowledge scores in oral health care were influential factors for oral hygiene. Young children who were brushed their teeth at least twice a day (Adjusted OR = 1.56; 95%CI = 1.06-2.31) and a greater average score on oral health knowledge (Adjusted OR = 1.12; 95%CI = 1.00-1.26) had good oral hygiene. These findings emphasize the importance of toothbrushing at least twice a day for young children and the effects of caregivers’ knowledge on the oral hygiene of young children.
