Chemical treatment of the intra-canal dentin surface: a new approach to modify dentin hydrophobicity
Objective This study evaluated the hydrophobicity of dentin surfaces that were modified through chemical silanization with octadecyltrichlorosilane (OTS). Material and Methods An in vitro experimental study was performed using 40 human permanent incisors that were divided into the following two gr...
