Knowledge and behaviours regarding the infant oral health visit among dental nurses and dental hygienists in Ireland

Abstract Aims To explore the knowledge and behaviours regarding the infant oral health visit among dental nurses(DN) including registered(RDN) and non-registered(NRDN) and dental hygienists(DH) in Ireland. Methods This cross-sectional, mixed-methods study assessed the knowledge and behaviours of Irish DN and DH knowledge and behaviours regarding infant oral health visits. Quantitative survey data was analysed using SPSS, while qualitative focus group discussion was thematically analysed to explore barriers and practices in early oral health promotion. Results The overall response rate was 38% (122 respondents). Results indicate that parental education was the most common procedure performed (22.3%) and fluoride interventions were least commonly performed. Lack of parental requests (32.5%) was identified as the primary barrier. RDN were significantly more likely to treat paediatric patients (74.5%) than DH (40%). Those receiving both theoretical and clinical training were significantly more likely to provide care to infants (78.9%). Public DN and DH treated significantly more children (89.7%) than private (44.2%). Older graduates (1960–1979) were more aware of the recommended first dental visit (83.3%). Conclusion This study highlights significant gaps in the knowledge and behaviours of DH and DN regarding infant oral health in Ireland, with inconsistencies in education, limited clinical exposure, and low parental awareness serving as key barriers. Variability in training and practice settings, particularly the greater involvement of public-sector DN in infant care, underscores disparities in service delivery. Additionally, inconsistent fluoride varnish application and a lack of consensus on the ideal age for a first dental visit further hinder early preventive care. Addressing these challenges through evidence-based education for DN and DH will ensure equitable access to preventive care for all infants.
