Brief 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.

Outcome Measures
Primary Outcomes (12)
Marginal Staining: World Dental Federation (FDI) Criteria - Baseline
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.

Marginal Defect: World Dental Federation (FDI) Criteria - Baseline
The World Dental Federation (FDI) criteria is 5-point ordinal scale with a score of 5 indicating the worst marginal defect. 1. Harmonious outline, no gaps. 2. Slight ditching, slight step/flashes, minor irregularities. 3. Major irregularities, ditching or flash, steps 4. Larger irregularities or steps (repair necessary) 5. Generalized major gaps or irregularities. Margins were assessed quantitatively as 2 different proportions (100% and \<100%) of the total length of the margin that is of Score 1 quality.

Marginal Defect: United States Public Health Service (USPHS) Criteria - Baseline
The United States Public Health Service (USPHS) criteria is 3-point ordinal scale with the 'C' indicating the worst defect. A) Undetectable. B) Detectable - V-shaped defect in enamel only and catches explorer going both ways. C) Detectable - V-shaped defect to the dentin-enamel junction Outcome will be reported as a single score at baseline.

Study Arms (2)
Group 1
EXPERIMENTALGroup 1: Lesion-specific cavity design with 90 degree cavosurface angle throughout the cavity margins
Group 2
EXPERIMENTALLesion-specific cavity design with wide bevel throughout the cavity margins
Interventions
Lesion-specific cavity design with 90 degree cavosurface angle throughout the cavity margins will be prepared. The total etch method will be performed, i.e. with a 32% by weight phosphoric acid (3M Scotchbond™ Universal Etchant) on enamel and dentine for 15 seconds. The etchant will be rinsed away and an adhesive (3M Scotchbond™ Universal Adhesive) will be applied on dentine with a microbrush for 20 seconds. The adhesive will be light-cured for 10 sec with the Elipar S10 curing light (3M Oral Care). Subsequently the preparation will be restored with a bulkfill resin composite (3M Filtek™ One Bulk Fill Restorative) and cured for 20 seconds.
