Study Summary
The aim of the study is to compare the short-term marginal integrity of two preparation techniques for Class I composite restoration using two visual assessment techniques, the FDI World Dental Federation and US Public Health Service assessment criteria. In addition, Optical Coherence Tomography (OCT) will be used to assess the marginal integrity of the restoration.
Primary Outcome
The World Dental Federation (FDI) criteria is 5-point ordinal scale with a score of 5 indicating the worst marginal staining. 1. No marginal staining 2. Minor marginal staining, easily removable by polishing. 3. Moderate marginal staining, not esthetically unacceptable. 4. Pronounced marginal staining; major intervention necessary for improvement 5. Deep marginal staining, not accessible for intervention. Outcome will be reported as a single score at baseline.
Interventions
- DEVICE Composite with 90 degree cavosurface angle
- DEVICE Composite with wide bevel
