Occupational asthma due to unheated polyvinylchloride resin dust.
Polyvinylchloride (PVC) resins are widely used in industry. Asthma due to the thermal degradation products of PVC are well documented. In this first case of occupational asthma due to unheated PVC resin dust the patient was exposed to PVC resin dust during the mixing of chemicals used for making plastic seals for bottle caps.
متن کاملRemoval of lead compounds from polyvinylchloride in electric wires and cables using cation-exchange resin.
Recycling treatment of cable insulation resin generated from electric wires and cables was investigated. Conventional insulation PVC contains a lead component, tribase, as a thermal stabilizer and lead removal is necessary to recycle this PVC as insulation resin. This paper describes a solid surface adsorption method using ion exchange resin to remove the fine lead containing particles from PVC...
متن کاملEffect of resin coating on dentin bonding of resin cement in Class II cavities.
This study was designed to evaluate the efficacy of resin coating on the regional microtensile bond strength (MTBS) of a resin cement to the dentin walls of Class II cavities. Twenty mesio-occlusal cavities were prepared in human molars. In 10 cavities, a resin coating consisting of a self-etching primer bonding system, Clearfil SE Bond, and a low-viscosity microfilled resin, Protect Liner F, w...
متن کاملMicroleakage Evaluation of Class II Composite Resin Restorations with Different Thicknesses of Resin-Modified Glass Ionomer
Background and Aim: One of the weaknesses of Class II composite resin restorations is gingival microleakage which contributes to postoperative sensitivity and secondary caries. The aim was to evaluate the microleakage in Class II composite resin restorations with different thicknesses of resin-modified glass ionomer (RMGI). Materials and Methods: In this in-vitro study, standardized Class II s...
متن کاملOccupational contact urticaria caused by polyvinylchloride gloves.
Allergy to natural rubber latex (NRL) gloves in healthcare workers is well recognized, and usually presents as immunological contact urticaria and sometimes anaphylaxis. Latex gloves can also cause allergic contact dermatitis, mostly because of rubber accelerators. As latex sensitivity is well known in healthcare settings, synthetic latex-free gloves are widely used. The most popular latexfree ...
