The "white line" which shows up occasionally when finishing a composite restoration between the restoration and tooth structure is caused by what?
The inherent optical properties of composite which naturally create a halo effect around the margin
Overheating the composite during the finishing process
Polymerization shrinkage, which tears the composite at the margin with the tooth
Uncured resin that turns white in color during polishing
