Category
Rating and criteria
Marginal adaptation
A: explorer does not catch B: explorer catches, no crevice is visible into which explorer will penetrate C: obvious crevice at margin, enamel, dentin, or base exposed D: restoration mobile, fractured, or missing
Surface texture
A: no surface porosities or cracks B: slight surface porosities or cracks C: obvious surface porosities or cracks
Anatomical form
A: the restoration is continuous with tooth anatomy B: Slightly under- or overcontoured restoration; marginal ridges slightly undercontoured; occlusal height reduced locally C: wear beyond the DEJ (clinically unacceptable) D: restoration is missing partially or totally; fracture of tooth structure; showing traumatic occlusion
Marginal discoloration
A: no discoloration anywhere along the margin B: superficial staining (removable, usually localized) C: deep staining (not removable, generalized)
Color match (immediately after placing the restoration)
A: no shade mismatch in room light in 3-4 seconds B: perceptible mismatch but clinically acceptable C: obvious mismatch, esthetically unacceptable
