Abstract

Objective. The aim of this study was to assess the erosive potential of a range of commercially available baby drinks in the laboratory. Methods. The erosive potential of each product was assessed by measuring its initial pH, neutralizable acidity, and ability to erode primary and permanent enamel. These parameters were compared to those of an orange juice positive control. Results. The initial pH of the baby drinks ranged from 3.5 to 4.0 with their neutralizable acidity ranging from 5.76 to 16.02 mL of 0.1 m NaOH. The amount of primary enamel removed following 1-h immersion in the drinks ranged from 3.77 to 8.10 microns, while the amount of permanent enamel removed ranged from 1.09 to 4.86 microns. In comparison, the orange juice control (Tropicana smooth) had an initial pH of 3.86, a neutralizable acidity of 37.0 mL of 0.1 m NaOH, and removed 6.39 microns of primary enamel and 5.32 microns of permanent enamel. Conclusion. All the baby drinks tested were found to be erosive; some of the products were as erosive as orange juice.
