Is this trial a fit for you?
✓Likely a good fit
Adults with three pairs of buccal cervical supragingival carious lesions in anterior teeth, good oral hygiene, and willingness to attend a 2-year follow-up.
✕Probably not a fit
Patients with poor oral hygiene, ongoing periodontal disease, smoking, or conditions that affect healing may not benefit from the findings.

What this trial studies
This interventional study compares the effect of three different finishing and polishing systems on ormocer and methacrylate-based bulk-fill flowable composites used in Class V restorations of anterior teeth. Each participant receives both materials in paired restorations and is followed at 2 weeks, 6 months, 18 months, and 24 months. Outcomes are assessed using FDI criteria for esthetics, function, and biology to determine which finishing/polishing approach provides the best long-term performance. The trial aims to guide clinicians in selecting the most suitable finishing/polishing system for these materials in Class V cases.
Why it matters
Potential benefit: If successful, this trial could help dentists choose polishing protocols that improve the longevity and appearance of Class V restorations.
How similar studies have gone: Prior work has explored finishing/polishing effects on composites, but this specific comparison between ormocer and methacrylate bulk-fill materials in Class V restorations is not extensively established.
