Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 to 65 with at least two non-carious cervical lesions in their premolars or canines.

Probably not a fit

Patients with medical conditions that interfere with dental care or those with periodontal disease in the target area may not benefit from this study.

What this trial studies

This clinical trial evaluates the effectiveness of various resin composites and adhesive techniques in restoring non-carious cervical lesions (NCCLs) in patients. A total of 52 participants will have two NCCLs treated on opposite sides of their mouths, using either an etch-and-rinse or self-etching adhesive approach. The restorations will be monitored for retention and performance every six months over a two-year period. The goal is to determine which combination of materials and techniques yields the best clinical outcomes.

Why it matters

Potential benefit: If successful, this study could improve the longevity and effectiveness of dental restorations for patients with non-carious cervical lesions.

How similar studies have gone: Previous studies have shown varying success with different adhesive approaches in dental restorations, making this a relevant investigation in the field.
