Objectives. The purpose of this study was to assess and compare the amount of toothpaste used by varying opening diameter and squeezing methods in children aged 3∼5 to prevent the excessive use of fluoride toothpaste.
Methods. The amount of toothpaste per brushing was measured from a sample of 176 infants aged 3∼5 in 6 nurseries located in Jecheon City, Chungbuk Province, Korea. We tested two squeezing methods, pea-size and transverse technique, and two openings, 0.6 cm and 0.9 cm. We compared the amount of toothpaste used relative to opening diameter and squeezing methods through paired t-test using SPSS 14.0.
Results. For 0.6 cm or 0.9 cm diameters with the pea-size method, the amount of toothpaste used was 0.22 g or 0.51 g, respectively (p＜0.001). For 0.6 cm or 0.9 cm diameters and the transverse technique, the amount of toothpaste used was 0.20 g or 0.46 g, respectively (p＜0.001). In case of 0.9 cm diameter, the amount of toothpaste showed significant difference according to squeezing methods (0.9 cm: p=0.045, 0.6 cm: p=0.121).
Conclusions. Smaller openings restrict the amount of toothpaste used and would reduce unnecessary fluoride ingestion.
