摘要: Trichloracetic acid is recommended For the treatment of external cervical root resorption. The present study examined effect 90% trichloracetic on microhardness and surface morphology human dentin enamel. Intact extracted teeth were sectioned embedded in acrylic resin. Each tooth was grinded highly polished exposing a flat den Lin treated with trichloracelic for 30, 60 90 s. Vicker's enamel assessed each before after treatment. In addition add via SEM. results showed that caused second order type reduction microhardness, as well structural changes both
