Assessing color stability and wear resistance of injectable and preheated composite materials

Color Stability and Wear Resistance of Direct Flowable and Preheated Resin Composite Veneers Using the Injectable Resin Technique: A Randomized Controlled Clinical Trial.

Not applicable Interventional King Abdullah University Hospital · NCT06532916

This study is testing whether heated composite dental materials last longer and keep their color better than flowable composites in patients needing front tooth restorations.

What this trial studies

This clinical trial aims to evaluate the color stability and wear resistance of highly filled injectable flowable composite materials compared to preheated conventional composites. It will involve a modified split-mouth randomized design with 20 patients requiring at least 6 anterior aesthetic restorations. A total of 142 restorations will be assessed over 12 months, with evaluations of color stability using a shade guide and spectrophotometer, and wear resistance through volumetric loss measurements using 3D laser scanning. The study seeks to determine if heated composite restorations outperform flowable composites in clinical performance.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with sound anterior teeth needing aesthetic restorations.

Not a fit: Patients with contraindications for dental treatment, poor oral hygiene, or severe aesthetic requirements not met by direct veneers may not benefit.

Why it matters

Potential benefit: If successful, this study could lead to improved aesthetic outcomes and durability of dental restorations for patients.

How similar studies have performed: While this approach is novel, similar studies have shown promising results in evaluating composite materials, indicating potential for success.
