Abstract
The aim of this study is to evaluate the effects of the association of 1064 nm Nd:YAG and 980 nm diode laser with irrigation protocols in microhardness and roughness of bovine root dentin. 25 bovine incisors will be longitudinally split into 2 halves (n = 50). The initial values of the samples will be obtained from cervical, middle and apical root third in which the subsurface microhardne…
