BACKGROUND The influence of parental education, choice of child dentifrice, and its impact on their children's dental caries experience remain unclear. AIM To investigate (i) dentifrice types used by Australian pre-school children, (ii) demographic factors that influence parents' dentifrice choice, and (iii) whether dentifrice type is related to pre-schooler's caries experience. DESIGN 155 parent-child dyads were recruited from five random metropolitan childcare centres. Parents completed a questionnaire recording relevant demographics and child dietary preferences, oral hygiene practice and dental visits. One calibrated operator performed a clinical examination of their pre-schooler for evidence of carious lesions. Data were analysed, and comparisons between variables made using chi-square tests and regression models. RESULTS 50% of pre-schoolers used <1000ppm fluoride dentifrice and 29% used non-fluoridated dentifrice. Higher parental education level was associated with the use of non-fluoridated dentifrice (p=0.02, χ2 =0.034). Children with higher brushing frequency were more likely to use fluoridated dentifrice (p=0.03, χ2 <0.001). CONCLUSION The proportion of Australian pre-schoolers using non-fluoridated dentifrice was higher than in other world regions. Higher parental education level was strongly associated with choosing non-fluoridated toothpaste, which warrants further qualitative analysis to assess determinants for parents' choice of child dentifrice.
