Objective: The aim of this study was to evaluate parents’ knowledge, attitudes, and practices (KAP) about the health care of primary teeth of children whose primary teeth had pulp diseases and explore the factors associated with the KAP of parents in Vietnam.
Materials and Methods: This was a cross-sectional study. 421 parents were recruited from the School of Odonto-Stomatology, Hanoi Medical University and Department of Dentistry, National Children's Hospital from December 2018 to June 2020. Data was collected using a questionnaire. Hidden class analysis was performed to classify the participants, and logistic regression analyses were used to determine the factors that affected the parents’ KAP.
Results: The proportion of parents with an appropriate knowledge, attitudes, and practices was 54.63%,
62.95%, and 42.28%, respectively. Financial barriers to dental/oral care prices (aOR = 4.46, 95% CI: 1.46–13.62), having a stable job (aOR = 2.26, 95% CI: 1.19–4.31), and multiple-child families (aOR = 2.06, 95% CI: 1.07–3.99) were associated with the parents’ KAP concerning taking care of their children’s primary dentition.
Conclusion: More than half of the parents participating in the study had the appropriate knowledge and attitudes and nearly half of them used the appropriate practices for taking care of their children’s primary teeth. The factors associated with parental KAP are income, job, and the number of children.
