The surface-penetrating sealant was introduced to fill micro-irregularities by capillary action, providing a uniform, regular surface and enhancing the surface smoothness. The application of unfilled low-viscosity surface sealants aims to enhance the luster, smoothness, and color stability of esthetic restorations and decrease stain absorption. They have low viscosity that enables them to easily spread and penetrate over these finished and polished surfaces, which may affect the life of the restoration positively. Additionally, it decreases surface porosity and creates a surface that is more thoroughly cured, improving the composite's stain resistance.\n\nThis prospective, parallel-group, randomized clinical study aims to compare the clinical effectiveness of using surface sealants on cervical resin composite restorations versus non-sealed restorations. Restorations will be assessed at baseline, 6, 12, 18, and 24 months using modified USPHS criteria. The primary outcome will be assessing marginal discoloration, and the secondary outcomes will be assessing color match, secondary caries, postoperative sensitivity, surface texture, and marginal adaptation.
