Table 1 Description of scores of FDI subcategories used to assess the restoration of this study
Subcategories | 1 Clinically excellent | 2 Clinically good | 3 Clinically sufficient/satisfactory | 4 Clinically unsatisfactory | 5 Clinically poor |
|---|---|---|---|---|---|
Marginal staining | No marginal staining | Minor staining, but easily removable by polishing | Moderate marginal staining, not esthetically unacceptable | Pronounced marginal staining; major intervention necessary for improvement | Deep marginal staining, not accessible for intervention |
Marginal adaptation | Harmonious outline, no gaps, no white or discolored lines | Marginal gap (< 150 μm), white lines. Small marginal fracture removable by polishing. Slight ditching, slight step/flashes, minor irregularities. Gap < 250 μm not removable | Several small marginal fractures. Major irregularities ditching or flash, steps. Gap > 250 μm or dentine/base exposed | Severe ditching or marginal fractures. Larger irregularities or steps | Restoration (complete or partial) is loose but in situ. Generalized major gaps or irregularities |
Recurrence of caries | No secondary or primary caries | Very small and localized demineralization | Larger areas of demineralization | Caries with cavitation | Deep secondary caries or exposed dentine that is not accessible for repair of restoration |
