Brief Summary

The current study aimed to evaluate the color change potential of wheat grass and white tea on post orthodontic white spot lesions (WSLs). Materials and Methods: A total of 12 patients were divided into two main groups A1 and A2 according to type of treatment agent (n=6). The A1 group used 10% white tea solution while the A2 group used 10% wheat grass solution. Shade evaluation was conducted using VITA Easyshade V spectrophotometer. Baseline L a b values of WSLs were detected right after orthodontic bracket removal. Patients were requested to rinse with the treatment agent for 1 minute, twice per day. The mean L,a,b values were recorded after 1 month and after 3 months . ΔE values were calculated between baseline, 1 month and 3 months after the treatment agent application and subjected to statistical analysis using one way ANOVA with p\>0.05. Also, Standardized photographs were taken at baseline, after 1 and 3 months. Each WSL was photographed twice with the 1st photograph taken of wet teeth and the 2nd one after prolonged air-drying in order to perform ICDAS II scoring.
