title: [Experimental study of root dentine permeability for medicines].
abstract: The use of contemporary endodontic methods of treatment do not always result in elimination of chronic nodus in periodontum, and filled teeth often remain potential noduses of infection, notwithstanding the impression of clinical and roentgenological wellness. Study of permeability of tooth root dentine under effect of medicines and microorganisms was done by means of introduction of colorant into the canal by iodine-electrophoresis method, observation of permeability of medicine from the canal through hard tissues of tooth and inhibition of growth of microorganisms in nutrient medium. It has been found out that the maximum permeability of tooth root dentine was observed in the cervical third of the root.
