Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To clinically evaluate the performance retention rate of a universal adhesive system containing nanoencapsulated quercetin in the self-etch mode, in composite resin restorations of non-carious cervical lesions after baseline, 6, 12, 24, 36, 48, and 60 months, when compared to a universal adhesive system (without nanoencapsulated quercetin). The evaluations will be conducted using the World Federation Criteria (FDI) and United States Public Health Service (USPHS) criteria. | — |
Secondary
| Measure | Time frame |
|---|---|
| To clinically evaluate the performance marginal discoloration and marginal adaptation, postoperative sensitivity, and recurrence of caries of a universal adhesive system containing nanoencapsulated quercetin in the self-etch mode, in composite resin restorations of non-carious cervical lesions after baseline, 6, 12, 24, 36, 48, and 60 months, when compared to a universal adhesive system (without nanoencapsulated quercetin).
