conclusions estelite sigma quick composite had wear resistance similar to that of nano- and microfilled composites. estelite flowable composites demonstrated similar wear resistance to that of a posterior composite. results the wear amounts of the composites are as follows in order: estelite sigma quick (1886.9 ± 518.5 μm2), estelite flow quick (2708.9 ± 578.1 μm2), estelite high flow (3206 ± 2...

BACKGROUND Contrary to the situation for amalgam restorations, obtaining acceptable proximal contacts with posterior composite restorations can be difficult. Proximal contacts that are less than ideal may permit food impaction and subsequent caries formation and periodontal problems. PURPOSE The aim of this study was to assess the quality of proximal contacts of posterior composite restoratio...

The objective of this study was to compare the clinical performance of a stror.~.tium glass-filled composite resin (Profile ®) and an amalgam alloy (Ease®) in primary molars. A total of 111 restorations (61 composite resin, 50 amalgam) were placed in 37 children. The PHS Clinical Rating Syste~n was used to evaluate color match, cavosurface marginal discoloration, anatomic form, marginal adaptat...

T he superior physical properties of composite resins have aroused the possibility of their use beyond the accepted indications for acrylic resin and silicate cement. The literature has suggested the use of composite resin for Class I,‘m4 Class II,” and Class IV39 * restorations. Other reports advocated the use of composite resin or tested the influence of pins on the physical properties of com...
