In a study by Franzman et al., it is suggested “that children should use dentifrice carefully and also, they should use only a pea sized amount, particularly at about 24 months of age.” As a result of these recommendations, the questionnaire contained a question to assess whether parents knew what a pea size was by having four different size circles representing peas. 76.0% of those who answered correctly chose the smallest circle as the size of a pea(Appendix 1).
