Guest guest Posted May 1, 2012 Report Share Posted May 1, 2012 hi guys1.BOTH AH 26 AND AH PLUS ARE RESIN BASED SEALERS AND ARE CYTOTOXICIn an earlier literature survey, epoxy-based materialswere deemed as highly cytotoxic. Formaldehyde isreleased from some epoxy-based materials duringand shortly after setting (15, 16). This fact and theresults from cell culture studies indicate that epoxybasedmaterials have a high initial cytotoxicity thatdiminishes by aging of the test specimensNumerous root canals filling materials are available in the field of dentistry, based on various formulas that contain a variety of different and partly mutagenic components, such as epoxy resin sealers, Ca(OH)2-based materials, and zinc oxide-eugenol cements. AH Plus root canal sealer will not release formaldehyde according to the manufacturer, although AH26 does. The purpose of this study was to analyze the leakage of lactate dehydrogenase (LDH) from rat hepatocytes after treatment with AH26 and AH Plus root canal sealers in vitro. Hepatocytes from male Sprague-Dawley rats were used to test the cytotoxicity of AH26 and AH Plus. The root canal sealers were mixed and then dissolved in the dimethyl sulfoxide to final concentrations of 0.01%, 0.04%, and 0.1% (wt/vol), with a dimethyl sulfoxide concentration of <0.05%. Dosage-dependent and time-dependent lactate dehydrogenase leakage values were measured and tested by one-way ANOVA. The results showed that both AH26 and AH Plus are toxic to rat hepatocytes. At a low concentration, AH26 had a higher toxicity than AH Plus to rat hepatocytes.US ETHE FOLLOWING ARTICLE TO CHECK THE TRADE NAMES FOR RESIN BASED SEALERSBUT AHPLUS AND AH26 WERE THE MOST COMMON DENTSPLY PRODUCTS USED IN UKSO they are enoughhttp://www.endoexperience.com/documents/PIIS0099239909008978.pdfAS WELL AS2.
