Present study aimed to improve the bond strength of denture teeth acrylic resin base by chemical or mechanical modification on bonding surface teeth. Total 40 artificial central incisors and lateral were divided into five groups: group I, 8 samples without (control group); II, (bonding treated with monomer); III, monomer glaze layer removed aluminum oxide stone bur); IV, acetone); V, (acetone a...

Gloves afford hand protection by minimizing skin contact. The effectiveness of medical gloves to protect against permeation of the monomers, methyl methacrylate (MMA), ethylene glycol dimethacrylate (EGDMA), and 1,4-butanediol dimethacrylate (1,4-BDMA), was assessed focusing on permeation rates and degradation of glove materials caused by monomer contact. Fifteen different brands of gloves were...

Front Cover: Caffeic acid is a component of coffee beans and bears catechol functionality. In article number 2100378 by Kotaro Satoh co-workers, caffeic acid-derived styrene monomer amenable to RAFT polymerization, which one the emerging methodologies for polymer synthesis. Combined with protection/deprotection processes, polymerization results in welldefined functional block copolymers consist...

: a new fibrous adsorbent was prepared by grafting acrylic acid /acryl amide (aa/aam) co-monomers onto poly(ethylene terephtalat) (pet) fibers. the resulting sorbent has been characterized by fourier transform infrared spectroscopy (ft-ir), thermo gravimetric analysis (tga), scanning electron microscopy (sem) and elemental analysis and studied for the preconcentration and determination of trace...

Occlusal wafers are commonly used to establish the intermediate and final position of the occlusion during orthognathic operations. Various problems have been experienced in the construction of these wafers. Acrylic wafers have poor compressive and tensile characteristics, take time to make, and are bulky. They can also distort while curing, increasing the risk of inaccurate localization of the...

In this paper, grafting of acrylic acid monomer on Gum tragacanth was performed. Variable of experiment included concentration of initiators and monomer, time, and temperature. Grafting efficiency was measured in the term of percentage of grafting (%G) and percentage of grafting efficiency (%E). Effectiveness of grafted gum in ferrous ion removal at different condition was assessed. According t...

The molecularly imprinted polymers for gallic acid were synthesized by precipitation polymerization. During the process of synthesis a non-covalent approach was used for the interaction of template and monomer. In the polymerization process, gallic acid was used as a template, acrylic acid as a functional monomer, ethylene glycol dimethacrylate as a cross-linker and 2,2'-azobisisobutyronitrile ...

The purpose of the study was to verify the linear displacement of teeth in maxillary complete dentures influenced by different monomer-polymer ratios - according to the manufacturer's instructions, with 25% excess or 25% less monomer content - in the conventional and microwaved polymerization techniques. Wax base plates and wax planes were made on edentulous maxillary stone casts according to t...
