Clarithromycin, an antibacterial agent, is extremely bitter in taste. The present research communication deals with development of taste masked resinate of clarithromycin using Tulsion-335, an acidic cation ion exchange resin. The drug resin complexes were prepared by batch process by taking drug to resin ratios of 1:1, 1:2, 1:3 and 1:4. The drug resin complexation procedure was optimized with ...

AIM The purpose of this study is to evaluate the clinical performance of three different restorative materials in primary teeth according to the FDI criteria. MATERIALS AND METHODS Resin-modified glass ionomer cement, compomer and composite resin restorations (n=93) were made in 31 patients. The restorations were clinically evaluated at baseline, 6th, 12th and 18th month with the FDI criteria...

The purpose of this study was to assess the antibacterial efficacy of incorporating catechins into 4META/MMA-TBB resin against Streptococcus mutans and to measure the shear bond strength of a metal bracket bonded to enamel using catechin-incorporated with 5% 4-methacryloyloxyethyl trimellitate anhydride (4-META)/methyl methacrylate (MMA)-tri-n-butyl borane (TBB) resin (catechin-resin). Catechin...

BACKGROUND Airborne contact dermatitis (AirbCD) is not uncommon, according to a large number of published case reports and review articles. Epidemiological data on AirbCD based on larger clinical samples have not yet been published. OBJECTIVES To investigate demographic characteristics and patch test reactivity in patients diagnosed with both occupational and non-occupational AirbCD. METHOD...

The use of self-adhesive resin cements is accomplished by a simple clinical step, in which the simultaneous demineralization/infiltration of the bonding substrate takes place. However, the self-adhesive resin cements have lower bond strength than conventional resin cements that rely on the application of etch-and-rinse adhesive systems. In order to increase the bond strength of the self-adhesiv...

Viscous heating becomes significant in the high speed resin coating process of glass fibers for optical fiber manufacturing. This study focuses on the coating resin flows inside the capillary coating die of optical fiber coating applicator and they are numerically simulated to examine the effects of viscous heating and subsequent temperature increase in coating resin. Resin flows are driven by ...

The present invention relates to a soybean-based adhesive resin including a soybean flour and a cross-linking agent. The cross-linking agent is reacted with the functional groups in the soybean flour to form an adhesive resin. The present invention also relates to a method of making a soybeanbased adhesive resin. This method involves providing an aqueous solution of soybean flour and adding a c...

PURPOSE Over the past years, the adhesion of fiber posts luted with simplified adhesive systems has been a matter of great interest. The aim of this study was to assess the post retentive potential of a self-adhesive resin cement using different adhesive systems to compare the push-out bond strengths of fiber posts. MATERIALS AND METHODS The post spaces of 56 mandibular premolar roots were pr...

A facile regioand chemoselective bromomethoxylation of alkenes under microwave irradiation conditions employing a new polymer supported brominechloride resin is reported. The resin is prepared from the commercially available chloride resin by a simple one step procedure.
