RESUMO
In experimental research on 52 removed teeth an opportunity of sharing of a technique nanoimpregnation dentin a root hydroxide cuprum-calcium (Cupral) and sealings root the channel with application polypropylene pins Flex Point Neo was studied. Before sealing of root channela in laboratory model there was carried out within 7 day galvanophoresis of hydroxide cuprum-calcium with the help of invented by author's galvanic pins. Then channels were sealed up by material Dentalis KEZ with polypropylene pins. Methods of dye microinfiltration and scanning electronic microscopy revealed high efficacy of the specified way of endodontic treatments, consisting in good hermetic sealing system of root channels. In addition the autors defined, that temperature sterilization and efforts to bend did not cause essential deformation of pins and they corresponded to the ISO requirements.
