Effect of different irradiation times on microhardness and depth of cure of a nanocomposite resin
Journal of the College of Physicians and Surgeons
To determine the microhardness and depth of cure of nanocomposite using different irradiation times on both upper and lower surfaces of composite material. In-vitro experimental study design. Dr. Ishrat-ul-Ebad Khan Institute of Oral Health Sciences, Dow University of Health Sciences and NED University of Engineering and Technology, Karachi, from March to May 2010. Total 120 cylinder shaped specimens; 60 specimens for depth of cure test and 60 specimens for micro hardness test were fabricatedpmid:21777529 fatcat:ujneygzunjb5nbftxkhm5qo5g4
