Abstract

Purpose: The current study aimed to evaluate the remineralizing potential of wheat grass and white tea on white spot lesions (WSLs). Materials and Methods: A total of 40 human enamel samples obtained by sectioning 20 molars were divided into two main groups according to type of treatment agent (n=20). Baseline microhardness values were obtained. All the specimens were immersed in demineralizing solution for 96 hours and evaluated again for surface microhardness. Following demineralization each solution was agitated for 3 minutes, then the specimens were subjected to pH-cycling model for 3 hours, then stored in artificial saliva. This cycle was repeated every 12 hours for 1 month and 3 months. After one and three months, the samples were evaluated for surface microhardness. Results: Percentage of microhardness recovery after 1 month for white tea and wheat grass were 88.5% and 94.6% respectively and after 3 months were 90.4% and 98.3% respectively with no statistically significant difference between the two groups. Conclusions: White tea and wheat grass could be considered as effective remineralizing agents that could be suggested for post-orthodontic WSL management.
