[Optical and scanning electron microscope study of gingival microleakage in Class II composite restorations].
It has been studied the gingival microleakage and the polymerization contraction gap in composites class II restorations. The influence of two different composites, a microparticle [Heliomolar (Vivadent)] and a high filled one [P-50 (3M)], has been compared with different adhesion systems: a) gingival enamel acid-etch technique. b) Dentinal adhesives [Gluma (Bayer) and Scotchbond 2 (3M)]. c) A adhesive varnish [Dentin Protector (Vivadent)]. The gingival microleakage is only prevented when a microparticle composite [Heliomolar (Vivadent)] and a adhesive varnish [Dentin Protector (Vivadent)] are used together.
