RESTORATIVE DENTISTRY
designed for restorations performed with
any material, not only GIC. It is clear that by
doing so the present trial may not be directly
comparable with other studies. Another
limitation of the present study is the lack of
a control material. The trial was nevertheless
mainly designed to test the hypothesis that a
modern, high-viscosity, coated GIC could be
a viable material for permanent restorations
under certain conditions. Further prospective
clinical trials may be performed in order to assess,
under conditions similar to the present trial, which
survival rates may have high-viscosity, coated
GIC restorations on the long-term when
compared to the gold standard of resin-based
composite restorations.

According to the results described, a dental
restorative system consisting in a high-viscosity
glassionomer cement and a lightcurable,
nanofilled resin coating appears to represent
a viable, fast, aesthetically satisfying alternative for
