Toxicokinetic of HEMA in guinea pigs
Journal of Dentistry, 2002Unconverted 2-hydroxyethylmethacrylate (HEMA) can be released from dental resin materials and can enter the body in humans. In the present study the uptake, distribution and excretion of 14C-HEMA applied via different routes were examined in vivo in guinea pigs.HEMA (0.02 mmol/kg bw labelled with a tracer dose 14C-HEMA 0.3 Bq/g bw) was administered by ...

Symptomatology of HEMA Contact Lens Wear
Optometry and Vision Science, 1989 ABSTRACT Identification of the determinants of patient symptoms is a requisite for successful patient management in contact lens practice. Symptoms reported by 104 patients wearing hydroxyethyl methacrylate (HEMA) contact lenses, who presented consecutively to a large contact lens clinic, were analyzed.

In vitro cytotoxicity and dentin permeability of HEMA
Journal of Endodontics, 1996 An in vitro diffusion chamber was used to measure the diffusion of 2-hydroxyethyl methacrylate (HEMA) through etched human dentin disks. Concentrations of HEMA, which diffused through dentin, were measured by ultraviolet spectroscopy, and the effect of initial HEMA concentration, dentin thickness, and back pressure on diffusion were assessed.

Biological clearance of HEMA in guinea pigs
Biomaterials, 2002No toxicokinetic data are available about the dental composite component 2-hydroxyethylmethacrylate (HEMA) in vivo in the literature. Therefore, the excretion of HEMA in feces and urine in vivo and, using the pendular perfusion technique with segments of jejunum and colon, in the biliary and enteric excretion in situ were investigated in anesthetized ...

Inflammatogenic and adjuvant properties of HEMA in mice
European Journal of Oral Sciences, 2005 2‐Hydroxyethylmethacrylate (HEMA), a common constituent in dental materials, is known to cause hypersensitivity reactions. While the means by which this small molecule causes adverse responses has not been ascertained, we have previously demonstrated that it binds to protein and in mice induces the production of autoantibodies to HEMA‐conjugated self ...

Thermoplastic copolymers of 2-hydroxyethyl methacrylate (HEMA) and methyl methacrylate (MMA) (molar ratio: 75/25 HEMA-MMA) were synthesized using HEMA containing different amounts of ethylene glycol dimethacrylate (EGDMA) to investigate their suitability for cell microencapsulation. Pure HEMA (0.0% EGDMA) was obtained with preparative chromatography to

Advanced Composites and Hybrid Materials, 2021
In the present study, the adsorption removal of anionic (MO) and cationic (MB) dyes with GO/HEMA and GO/HEMA/TiO2 and GO/Fe3O4/HEMA nanocomposites as adsorbents was investigated. Characterization of properties was determined by FTIR, XRD, SEM, TEM, EDX, and zeta potential analysis.

Effects of HEMA on water evaporation from water–HEMA mixtures
Dental Materials, 1998The aims of this research were: (1) to determine the relative rates of evaporation of water and HEMA, and (2) to determine the effects of increasing concentrations of HEMA on the rate of evaporation of water from water and HEMA mixtures.Ten microliters of each solution (100% H2O, 75% H2O-25% HEMA, 50% H2O-50% HEMA, 25% HEMA, 100% HEMA) were placed on ...
