Oral health and inflammation in patients with end-stage renal failure.

Background/aims: End-stage renal disease (ESRD) patients have an increased risk of atherosclerotic complications. In both hemodialysis (HD) patients and the general population, it has become evident that inflammation plays an important role in the pathogenesis of atherosclerotic complications. Oral and dental problems in ESRD patients could be an important source of inflammation, thus treatment of these problems is important to protect these patients from potential infections.

Influence of polymerization method, curing process, and length of time of storage in water on the residual methyl methacrylate content in dental acrylic resins.

This study compared the influence of different polymerization methods (heat, auto-, and microwave energy), different curing processes (in the case of heat- and autopolymerized specimens), and length of storage of the polymerized specimens in distilled water at 37 degrees C on the residual methyl methacrylate (MMA) content in dental acrylic resin specimens. Residual MMA of 120 resin specimens were measured using high-performance liquid chromatography. For the heat-polymerized resins, the lowest residual MMA content was obtained when they were given a long-term terminal boil and then stored in the distilled water for at least 1 day.
