METHOD FOR MODELING THE PRE-IMPLANTATION CONDITION OF A MOLAR ROOT CANAL IN CD LINE RATS Russian patent published in 2019 - IPC G09B23/28 A61C5/50 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, particularly to experimental dentistry, and aims at producing a model of the pre-implantation condition of the molar root canal. Method for modeling the pre-implantation condition of the molar root canal involves shortening the molar's coronal part, root canal entry and patency are determined; then, the trunk root canal is passed three times with the help of hand K-files No. 06/02, No. 08/02, No. 010/02, alternating with irrigation of the root canal after each instrument. Root canal washing is performed using endodontic syringes with solutions: 17 % ethylene diamine tetraacetic acid in amount of 1.0 ml, 2 % sodium hypochlorite in amount of 1.0 ml and distilled water in amount of 1.0 ml, followed by single irradiation of molar root canal with short-wave ultraviolet radiation at wave length 255±2 nm for 20 seconds by introducing the disposable light guide into the main canal molar channel to the stop.

EFFECT: method enables to obtain an adequate model of the pre-implantation state of the molar root canal without damaging the structural complex of periodontium tissues.
