RESUMO
Abstract Objective: To assess the knowledge level of parents from the central region of Saudi Arabia about oral health and care of preschool children and its relation with sociodemographic variables, parents' self-perception toward their dental health, importance of teeth, and frequency of dental visits. Material and Methods: A random sample of 754 parents participated in this cross-sectional study and completed an internationally accepted questionnaire. Chi-square test and logistic regression analysis were used to analyze the data (p<0.05). Results: Mean knowledge score of the parents was 4.8 (out of 11). Less than 20% of the parents were knowledgeable about the best position for tooth brushing, the concentration of fluoride in a child's toothpaste, timing of first dental check-up, and best time to give a sugary snack. Mothers, parents with high educational level and family income, parents with a positive attitude towards teeth and excellent self-perception of their dental health were significantly more likely to score higher (p<0.05). Conclusion: Knowledge of parents about oral health and care of preschool children in the central region of Saudi Arabia was deficient. Gender, education level of parents, family income, attitude about teeth and self-perception of parents' own dental health were factors, which influenced their knowledge. To improve parents' knowledge, health professionals' role should be improved, and TV commercials directed toward the areas, which had gaps in knowledge.
