Color Stability of S-PRG Resin-Based Light-Cure Varnish and Prophylaxis Paste on White Spot Lesions

The aim of the study is to evaluate and compare the long-term color stability of two bioactive materials used in the management of white spot lesions: Surface Pre-Reacted Glass (S-PRG) containing resin-based light-cured varnish and S-PRG containing prophylaxis paste. The study will assess color changes over a 12-month period to determine which material better maintains aesthetic integrity while providing therapeutic benefits for demineralized enamel surfaces.
