Comparing composite fillings and bonding methods for front-tooth dentin cavities.
Official title: Evaluation of Anterior Restorations
Run by Recep Tayyip Erdogan University · NCT07343063 · Data updated 2026-11-12
This project tests whether three types of composite fillings and two ways of applying a universal adhesive hold up equally well for people with dentin cavities in class III and IV restorations over 18 months.

Is this trial a fit for you?
✓Likely a good fit
Adults in good general health who need class III or IV composite restorations for dentin caries and who are not pregnant, breastfeeding, or affected by uncontrolled systemic disease or bruxism are ideal candidates.
✕Probably not a fit
People with advanced periodontitis, active bruxism, those undergoing orthodontic treatment, individuals with direct pulp capping, and pregnant or breastfeeding women are unlikely to qualify or benefit from participating.

What this trial studies
This observational study follows patients who receive class III or IV composite restorations made with one of three composite materials using a universal adhesive applied in either self-etch or total-etch mode. Restorations are evaluated over 18 months using the FDI clinical criteria to document retention, marginal integrity, sensitivity, and aesthetic outcomes. The hypotheses are that clinical success will not differ between the composite materials and will not differ between the adhesive application modes. The study is conducted at Recep Tayyip Erdogan University in Rize with standard inclusion and exclusion criteria to select medically healthy adult patients.
Why it matters
Potential benefit: If successful, the results could help dentists choose composite materials and bonding methods that last longer and require fewer re-treatments for front-tooth dentin cavities.
How similar studies have gone: Previous clinical studies of universal adhesives and different composite materials have shown generally favorable but mixed results, so this comparative approach is not entirely novel but adds needed head-to-head clinical data.
