Abstract
OBJECTIVE: To determine the erosive potential of seven different commercially available candy sprays in vitro and in vivo. MATERIAL AND METHODS: The erosive potential was determined in vitro by measuring the pH and neutralisable acidity. The salivary pH and flow rate were measured in healthy volunteers after administration of a single dose of candy spray. RESULTS: Candy sprays have an extremely low pH (1.9-2.3) and a neutralisable acidity varying between 0.8-1.6 ml of 0.25M NaOH. In vivo, candy sprays induced a short-term 3.0 to 5.8-fold increase in salivary flow rate with a concomitant drop in salivary pH to values between 4.4 and 5.8. CONCLUSION: All candy sprays tested have an erosive potential. This information is of use for clinicians counselling juvenile patients with dental erosion.
