Investigating parents' and prospective parents' knowledge of oral hygiene for infants and children

Background: The aim of this study was to investigate the knowledge of parents and future parents regarding the oral hygiene of newborns and children. Understanding parental awareness is crucial to identifying gaps in knowledge and improving early oral health practices. Methods: An anonymous questionnaire was constructed and disseminated to patients of dental practices and parents of children attending nursery and primary schools in municipalities between Vicenza and Padua. Data collection took place from January 2022 to June 2023, yielding 600 completed questionnaires, of which 532 were completed by women and 68 by men. Statistical analysis was performed to evaluate the influence of educational levels on oral hygiene knowledge and practices. Results: Significant differences (p < 0.05) were observed based on participants’ educational levels. Parents with higher educational attainment demonstrated better knowledge regarding the appropriate age to start oral hygiene, the impact of sugary drinks on tooth decay, and the transmissibility of carious disease. Among university-educated parents, 83.8% reported frequent brushing, compared to 76.4% of parents with only elementary or middle school education. Additionally, over 25% of respondents expressed concerns about toothpaste safety, and there was limited understanding of the importance of early oral hygiene practices and fluoride use. Conclusions: The findings highlight the need for targeted educational interventions to improve parents’ understanding of oral hygiene, with a particular focus on nutrition, bacterial transmissibility, and the importance of early oral care. Educators, healthcare professionals, and community programs should prioritize addressing the gaps identified, especially among parents with lower educational backgrounds, to foster better oral health practices from an early age.
