Color Stability of S-PRG Resin-Based Light-Cure Varnish and Prophylaxis Paste on White Spot Lesions
Sponsor: Cairo University
Summary
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.

Conditions
Interventions
S-PRG Barrier coat
A light-cured Giomer varnish for prolonged hypersensitivity relief. Seals and protects exposed dentinal tubules to prevent pain. Ideal for patients experiencing loss of enamel, gingival recession or temporary sensitivity due to whitening.
S-PRG Prophylaxis paste
S-PRG Prophylaxis paste is a bioactive Giomer-based paste containing S-PRG particles that release six therapeutic ions-fluoride, strontium, borate, aluminum, sodium, and silicate each contributing to remineralization, antibacterial effects, and dentin sensitivity reduction.
