Comparison of resin push-out strength to root dentin of bovine- and human-teeth
<b>Aim</b> : To compare the push-out strength of bovine- and human-root dentin and, thus, evaluate the suitability of bovine-root dentin to substitute human-root dentin for bond strength testing. <b> Materials and Methods</b> : Ten single-rooted human-teeth and ten bovine in...
