This study was to identify the erosive potential of acidic fruit juice on the enamel, and to analyze how the risk on surface is increased by the duration of exposure. Healthy extracted human premolar enamel surfaces were divided into 8 groups by exposure time, including the control group that was exposed to phosphate buffered saline (PBS), and 7 experimental groups that were exposed to 10 ml Taylor Prune Juice for 1, 3, 5, 15, 30, 60, and 120 minutes, respectively. The pH and sugar content of the beverage were measured, and micromorphology were examined by a scanning electron microscope (SEM). The beverage used in present study had a pH as low as 3.74. The effect on the tooth surface was compared by using SEM. It has been shown to cause tooth erosion, he changes on the tooth being damaged, and the tooth particles being exfoliated or cracked irregularly. In addition, it was found that the impact of surface damage increased with the duration of exposure. Based on the study results, avoiding prolonged exposure by consuming the beverage within 10 minutes may reduce the risk of damaging the teeth and help maintain good oral health.
