Abstract Aims To explore the knowledge and behaviours regarding the infant oral health visit among dental nurses (DNs), including registered (RDNs) and non-registered (NRDNs), and dental hygienists (DHs) in Ireland. Methods This cross-sectional, mixed-methods study assessed the knowledge and behaviours of Irish DNs and DHs regarding infant oral health visits. Quantitative survey data was analysed using IBM SPSS version 29, 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%, with 122 responses received from 321 questionnaires distributed. Results indicated 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. RDNs were significantly more likely to treat paediatric patients (74.5%) than DHs (40%). Those who had received both theoretical and clinical training were significantly more likely to provide care to infants (78.9%). Public DNs and DHs 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 The present study highlights significant gaps in the knowledge and behaviours of DHs and DNs 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 DNs 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 the timely delivery of early preventive infant oral healthcare. Addressing these challenges through evidence-based education for DNs and DHs will ensure equitable access to preventive care for all infants.
