简要总结
This study involves 35 patients, each receiving two Class I posterior composite restorations using a split-mouth design. One side will be treated with Omnichroma composite (test group), and the other with Tetric-N-Ceram (control group). A total of 70 cavities will be evaluated. Standard clinical procedures, including case history, radiographic and vitality assessments, and shade selection (for control group), will be performed. Cavities will be prepared, etched, bonded, and filled with designated materials using layered techniques. Restorations will be finished, and after 24 hours of rehydration, color match and stability will be assessed by three blinded evaluators using USPHS criteria and magnification tools.
