Today's clinical parameters of success with
composite
restoration in the anterior aspect are well-established.
A silicone index is often used in order to control the form
of teeth and helps in the building of the lingual wall as
well as with the localization of the incisal edge.
In order to simplify shade determination, manufacturers
have developed specific shade guides that give a recipe for the colors
to be used. But we still have to play with the material's light and transparency
to adjust surface brightness.
Thus, and for a better understanding of the optical reactions
of the composite
build-up, a colorimetric study gives very interesting answers
on the existing differences in between most recent composite
systems.
