[Class V cavities for composites. New preparation principles].

The aim of this study is to establish with the help of a computer a new type of Class V cavity that would ensure minimal marginal gap of restoration work using restorative resins. Comparison of computer graphics has shown that the ideal Class V cavity for restorative resins is cone-like with the apex or smaller base pointing towards the pulp and the walls slightly convex towards the free surface of the cavity. To prepare this sort of cavity new specular-type burrs are required.

[Surface polishing of posterior composites].

In this research we have valued at SEM the smoothness degree of the surface obtained in vitro on three kinds of composite resins for posterior restoration (P-30, P-50, Clearfil Photo Posterior); then we have compared it with the result obtained in vitro with an alloy not gamma-2 (Dispersalloy). The surfaces of the composite restorations show at SEM irregularities more or less accentuated for the presence of particles of filling got in comparison with the matrix. The surface of alloy restorations results on the contrary perfectly polished and completely comparable with the enamel surface.

[Surface polishing of anterior composites].

In this research it has been valued at SEM the smoothness degree of the surface obtained in vitro on three kinds of composite resins for anterior restorations (Lumifor, Silux, Pekalux). The surface has been polished and finished with abrasive disks (Sof Lex Pop On XT). The composite resin Lumifor presents at SEM a good finished surface. Far better results have been obtained with the microfilled composite resins Silux and Pekalux, which show at SEM surfaces perfectly polished and homogeneous.
