The aim of this randomized controlled clinical trial is to evaluate the 12-month clinical performance of restorations placed in NCCLs using universal adhesives with different compositions according to FDI criteria.
This controlled, randomized, single-blind clinical trial will compare the clinical effectiveness of three universal adhesive systems with different compositions in the restoration of non-carious cervical lesions. A total of 30 healthy volunteers aged 18-55 years will be included. Each participant must present with at least three vital posterior teeth with non-carious cervical lesions (≥3 lesions), with both enamel and dentin involvement and with antagonist teeth in occlusion. Each participant will receive restorations using all three adhesive systems in different teeth (split- mouth design). Randomization will be performed using a computer-generated randomization table (Research Randomizer Program). An experienced operator from the Department of Restorative Dentistry will perform all restorative procedures (AUT). Radiographs will be taken at baseline (before treatment) and at 12-, 24- and 36-month follow-up appointments to assess adaptation, marginal integrity, and proximity to the pulp. Additional radiographs will only be taken if clinically indicated (e.g., suspected endodontic involvement). Restorations will be evaluated immediately after placement, at 12-, 24- and 36-month using FDI evaluation criteria.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| G2 Bond Universal | Experimental | Enamel margins will be beveled (0.5 mm) using a flame-shaped diamond bur.Isolation will be achieved using cotton rolls and saliva ejector. Enamel surfaces will be etched with 35% phosphoric acid for 15 seconds, rinsed for 15 seconds, and dentin left slightly moist. Adhesives will be applied according to the manufacturer's instructions. A nanohybrid universal composite (OptiShade, Kerr Corporation, Orange, CA, USA) will be placed incrementally (≤2 mm layers) and light-cured. Finishing and polishing will be performed using OptiDisc discs and HiLuster polishing system (Kerr). |
