Staining Susceptibility Of Two Commercially Available Universal Composites - An Invitro Study

In contemporary restorative dentistry, achieving long-term esthetics is of paramount importance. Among the key factors influencing clinical success, colour stability of composite resins plays a vital role, especially in anterior restorations where esthetic demand is high. Over time, resin composites are prone to discoloration due to intrinsic factors such as resin matrix degradation and extrinsic factors such as dietary stains, smoking, and oral hygiene habits. This colour change may compromise esthetics and patient satisfaction, often necessitating premature restoration replacement[1].
