AIM The aim of this study was to evaluate the antibacterial effects of different one-step and two-step self-etching primer/adhesives on Streptococcus mutans (S. mutans), Lactobacillus casei (L. casei), and Lactobacillus acidophilus (L. acidophilus). METHODS AND MATERIALS The antibacterial effects of Clearfil Protect Bond Primer and Bonding agent; AdheSE Primer and Bonding agent; Adper Prompt ...

introduction : this in vitro study was designed to measure and compare the amount of temperature rise in the pulp chamber of the teeth exposed to different light curing units (lcu), which are being used for curing composite restorations. methods: the study was performed in two settings; first, an in vitro and second was mimicking an in vivo situation. in the first setup of the study, three grou...

BACKGROUND The study aims to investigate the effect of incorporation of sepiolite nanoparticles on the microtensile bond strength of an experimental dentin bonding to the human dentin. MATERIAL AND METHODS The sepiolite nanoparticles were incorporated into an experimental methacrylate-based dentin bonding system in concentrations of 0.0, 0.2, 1.0, 2.0, and 5.0 weight percents. The specimens w...

This article reports our study, carried out as a CECSMO assignment, assessing the effectiveness of resin modified glass ionomer cement as a bonding agent on enamel over a two year period and a consideration of the relative influence of two brands of attachments, Orthos and Damon. In our study group we had an overall rate of bonding rupture of 11.6%. 17% of direct and 33% of the indirect bonding...

Metal porous foams have been eliciting much interest in recent years due to their high capacity of energy absorption. The characteristics of the pores in these materials play an important role on their energy absorption capability and other properties. This study reports the fabrication of aluminum closed-cell foams by accumulative roll-bonding (ARB) technique using calcium carbonate (CaCO3) as...

The title compound, C(13)H(11)N(3)O, a potential chemotherapeutic agent, contains a essential planar [maximum deviation = 0.0144 (14) Å] quinoline moiety. The quinoline ring system and the five-membered heterocycle form a dihedral angle of 7.81 (6)°. In the crystal, inter-molecular non-classical C-H⋯N hydrogen bonding is present.

Uracil-terminated telechelic sulfonated polyimides (SPI-U) were transformed into noncovalent network membranes through biocomplementary hydrogen bonding recognition in the presence of an adenine-based crosslinking agent. SPI-U membrane exhibited dramatically improved methanol permeability, oxidative stability, proton conductivity, and selectivity relative to those of the standard SPI.

The utility of an external structure-directing agent to induce orthogonal H-bonding-mediated programmed supramolecular-assembly and gelation of an n-type NDI chromophore is reported. Further, the effect of π-stacking and morphology on electrical conductivity of semiconducting NDI building blocks is revealed.

This in vitro study evaluated the shear bond strength of a hybrid composite resin bonded to primary dentin prepared with an Er, Cr:YSGG hydrokinetic laser compared to conventional bur prepared primary dentin. The results suggest that primary dentin surfaces treated with the Er, Cr:YSGG laser, with or without etching, may provide comparable or increased composite resin bond strengths depending u...

Background & Aims: Repair of defective restoration is more conservative than replacing it. Veneering the amalgam restorations with opaque resin materials can satisfy the esthetic demands. Evaluation of interfacial bond quality between amalgam and composite surface is one of the important factors in assessing the quality of repaired amalgam which can be achieved...
