AIM To evaluate the pitting and crevice corrosion characteristics of stainless steel (SS) and NiTi endodontic files in R-EDTA and NaOCl irrigating solutions. METHODOLOGY The corrosion behaviour of two H-files produced from different SS alloys (Mani, AISI 303 SS, Dentsply Maillefer, AISI 304 SS) and one file produced from NiTi alloy (Maillefer) was determined in R-EDTA and NaOCl irrigating sol...

Abstract. The potentiodynamic experiments of the nickel effects on zinc electrodeposition have been done to understand impact Ni impurities electrowinning Zn from spent pickling liquor. chloride solutions concentrations 90 and 1 g/dm3 were used as electrolytes. latter was also mixed with in experiments. All runs carried out at room temperature 40 mV/s continuous polarization speed 1/s sampling ...

ultrasonography is the only practical method for obtaining images of the posterior segment of the eye when the light-conducting media are opaque. in this study, 182 dogs with ocular abnormalities presented to the department of veterinary surgery and radiology from december 2008-august 2010 were included. all the animals were subjected to detailed ophthalmic examination and b-scan ultrasonograph...

introduction bolus is a soft and resilient material which is used for increasing skin dose or to even out the irregular patient contour. the main property of various materials used presently as bolus is the water-equivalent electron density. ethyl methacrylate is used as a soft-liner in dentistry and its physical and chemical properties are proved to be nontoxic for human body. the goal of this...
