What this trial studies

This clinical evaluation aims to compare the two-year performance of Class I resin composite restorations using a universal adhesive with varying etch-and-rinse strategies (15-second and 5-second etching) and self-etch strategies. The study will be conducted as a double-blinded randomized clinical trial with a split mouth design, involving thirty adult patients seeking dental treatment. Participants will undergo three restorations each, and the study will adhere to ethical guidelines and informed consent protocols. The trial is set to take place at the Faculty of Dentistry, University of Mansoura, from December 2024 to December 2026.

Who should consider this trial

Good fit: Ideal candidates are adults with three primary occlusal caries in their upper or lower posterior teeth and good oral hygiene.

Not a fit: Patients with high caries risk, poor oral hygiene, or those undergoing orthodontic treatment or periodontal surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved techniques for dental restorations, enhancing their longevity and effectiveness.

How similar studies have performed: Previous studies have shown varying success with different adhesive strategies in dental restorations, making this approach both relevant and necessary.
