The manufacturers of some condensable posterior composites claim that their products can be placed in bulk and light-cured in 5-mm-thick increments. This study compared the shear bond strengths of three composite resins when bonded to dentin in 2- and 5-mm-thick increments. Overall the bond strengths were adversely affected by the composite thickness (p < 0.0001). The shear bond strength of eac...

Today, direct composite restorations in posterior teeth are a part of the standard therapy spectrum in modern dentistry. The performance of this treatment method in the masticatory load-bearing posterior region has been conclusively proven in many clinical studies, even for extensive composite restorations with cuspal coverage. These restorations are usually carried out in an elaborate incremen...

This paper proposes and discusses the use of composite marginal likelihoods for Bayesian inference. This approach allows one to deal with complex statistical models in the Bayesian framework, when the full likelihood and thus the full posterior distribution is impractical to compute or even analytically unknown. The procedure is based on a suitable calibration of the composite likelihood that y...

UNLABELLED Information on the longevity of fiber-reinforced composite fixed partial dentures (inlay FPDs) should be considered in the selection of materials, operative techniques and patient instructions related to prognosis and long-term cost-effectiveness. OBJECTIVE This study evaluated the long-term survival of fiber-reinforced, adhesively-bonded composite prostheses placed in posterior te...

polymerization contraction may produce defects in the composite - tooth bond. this may lead to bond failure and microleakage. the aim of this study was to reduce microleakage of posterior composites using different methods. 45 molar and premolars extracted teeth were choosen. the cavities were randomly assigned into 5 groups of 9. box-shaped cavities were prepared on each side of proximal surfa...

reasons for the limited lifespan of those restorations.2-5 Predominantly in recent years, these inadequacies have been greatly reduced through further developments in the materials of the composite and adhesive systems.6 Nevertheless, the negative effects of polymerisation shrinkage – such as poor marginal integrity, insufficient adherence to the cavity walls or cusp deflections – still represe...

Color characteristics of the shades for different filler type resin composites were compared in the reflectance and transmittance modes, and specular component included (SCI) and specular component excluded (SCE) geometries for reflectance mode. Resin composites and shades used in this study were submicron filled Estelite Sigma (Sigma: Inc, A2, A3, B3, C2, OA2, OA3) and nanofilled Filtek(TM) Su...

Resin composites have become the first choice for direct posterior restorations and are increasingly popular among clinicians and patients. Meanwhile, a number of clinical reports in the literature have discussed the durability of these restorations over long periods. In this review, we have searched the dental literature looking for clinical trials investigating posterior composite restoration...

Radiopacity is an important property of composite materials for clinical diagnosis. For seven direct composites (Aelite LS Posterior, Aelite All-Purpose Body, Quadrant Universal LC, Clearfil Majesty Posterior, Clearfil Majesty Esthetic, Filtek Ultimate Dentin, IPS Empress Direct Dentin) and six indirect composites (Ceromega, Epricord, Estenia C&B, Tescera, Signum Ceramis, Solidex), diskshaped s...

UNLABELLED Direct placement resin composite is revolutionizing the restoration of posterior teeth. Compared to amalgam, its use not only improves aesthetics but, more importantly, promotes a minimally invasive approach to cavity preparation. Despite the benefits, the use of composite to restore load-bearing surfaces of molar and premolar teeth is not yet universally applied. This may be due to ...
