Evaluation of the effect of expiration date on composite bond strength and color stability.

In clinical practice, adherence to proper storage conditions and expiration dates is essential to ensure the success and quality of resin composite materials, which are frequently used in routine dentistry. Within the limitations of this study, the color stability and bond strength of resin composites decreased after expiration dates. Therefore, to achieve optimal clinical results, it is crucial to ensure that restorations are performed using non-expired resin composites.
