To evaluate and compare the two-year clinical performance of Class I resin composite restorations utilizing a universal adhesive used in different etch-and-rinse strategies (15-second and 5-second etching) and self-etch strategies for bonding.
The experimental design description adhered to the guidelines provided by the Consolidated Standards of Reporting Trials (CONSORT) statement. The present study is planned as a double-blinded randomized clinical trial, ensuring that both the patients and the examiner are unaware of the treatment allocation. The trial will follow a split mouth design. A total of thirty adult patients, who are seeking dental treatment, will be enrolled in the study. The participants will be recruited from the Operative Department clinic at the Faculty of Dentistry, University of Mansoura. The study will focus on ninety Class I restorations. No active advertisement will be used for participant recruitment, and instead, a convenience sample will be formed. Prior to participating in the study, each patient will be required to provide informed consent by signing a consent form. The study is scheduled to be conducted from December 2024 to December 2026. The form and protocol of the study will be approved by Mansoura University's ethics committee before initiation. To determine the appropriate sample size, previous studies examining the clinical success rate of posterior Class I restorations restored using different adhesive strategies were considered. Based on various parameters, including a significance level of 5%, a test power of 80%, and an equivalence limit of 15%, the sample size was calculated. Considering a potential dropout rate of 20%, a sample size of 30 subjects (Three restorations per patient) was determined to be suitable.

| Postoperative hypersensitivity/pulp status | The postoperative hypersensitivity/pulp status will be assessed based on the updated FDI criteria. This parameter is evaluated by scoring the pain experienced during chewing and/or with cold or warm food items, as reported by the patient. The criteria consist of five scores: scores 1-3 indicate success, score 4 indicates the need for restoration repair, and score 5 indicates the need for restoration replacement. | Two years after restoration |
| Marginal adaptation | The marginal adaptation will be evaluated through visual examination using a 250 µm probe and brief air drying. This assessment will be conducted according to the updated FDI criteria. The criteria consist of five scores: scores 1-3 indicate success, score 4 indicates the need for restoration repair, and score 5 indicates the need for restoration replacement. | Two years after restoration |
