Comparing a self‑cured resin composite with a light‑cured bioactive composite for side cavities in back teeth

Clinical Performance of a Novel Self-cured Resin Composite Compared to a Light-cured Bioactive Resin Composite Restoration in Proximal Cavities of Posterior Teeth: A 2-year Randomized Controlled Clinical Trial

EARLY_PHASE1 · British University In Egypt · NCT07457749

This project will test whether a new self‑cured resin filling works as well as a light‑cured bioactive resin for repairing proximal cavities in adult posterior teeth.

What this trial studies

This single‑center interventional early‑phase study at The British University in Egypt compares clinical performance of a novel self‑cured resin composite against a light‑cured bioactive resin composite in proximal (Class II) cavities of posterior teeth. Adult participants (ages 18–47) with primary caries removal and good or moderate oral hygiene will receive restorations with one of the materials and return for scheduled recall visits for clinical evaluation and maintenance. Teeth with extensive prior restorations, periodontal disease, high caries activity, or other exclusions will be omitted to focus on primary proximal lesions. The trial is designed to see if the self‑cured material can simplify the procedure and maintain acceptable restoration outcomes compared with the light‑cured bioactive option.

Who should consider this trial

Good fit: Adults 18–47 years old with primary proximal caries in posterior teeth, good or moderate oral hygiene, no significant periodontal disease, and willingness to attend follow‑up visits are ideal candidates.

Not a fit: Patients with high caries activity, extensive prior restorations or endodontic treatment, significant periodontal disease, severe bruxism, pregnancy, or caries extending to the cemento‑enamel junction are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, the self‑cured resin could shorten procedure steps and chair time while providing comparable restoration performance.

How similar studies have performed: Related research on bioactive and alternative curing strategies has shown promising results for some materials, but direct comparisons between modern self‑cured and light‑cured bioactive composites remain limited.
