The use of three-dimensional heated gutta-percha for root canal obturation – the most modern technology, which has a long history of use. Termoplastificaion gutta- percha in injecting method is particularly advantage in complex form channels having ledges branching as network internal resorption, C – shaped or lateral canals, where the adaptation of the softened gutta-percha need it so this method is much better. Widespread method of three-dimensional obturation of the root canal and complications arising from its application, dictate the necessity for further in-depth study of this technique. The aim of the study was to estimate the average value of the temperature rise on the root surface when administered by heated plugger. Investigations were carried out on 15 premolars using ProTaper system according to the protocol of this system and also performed root canal irrigation 3% sodium hypochlorite solution. Washing and drying proceeded to obturation technique for continuous wave. After filling in the apical third channel middle and upper part was obturated with gutta-percha using the technique of injection. Measuring the temperature of the root surface was carried out by using an infrared imager Ti10-FLUKE (U. S. A.) from a distance of 25 cm at the end of heat plugger is introduced into the root canal. A termoplastification gutta-percha obturation and selling root temperature measurement were using an infrared imager. The minimum value of the measured temperature was 38. 1 C, the maximum – 84. 4 C. The wide range of results probably indicates that calibrate and standardize this technique is extremely difficult. The wide range of results probably indicates that calibrate and standardize this technique is extremely difficult. A big role in this case is human factor. In order to have projected temperature increases root, all heating devices should systematically go through the procedure of checking that at the moment is not feasible. In addition, lack of timer devices have not accurately measure the exposure time of heated plugger, reserving the right to choose a doctor exposure. Thus, modern appliances for obturation require further improvement. It is also necessary to conduct research in the direction of filling materials having not such a high operating temperature. The available literature on the topics covered extensively endodontic instruments and equipment issues, which must be obtained for root canal treatment at the present level. However, information about complications, which leads to their use, is limited. The reason may be the commercialization of research. Thus, planning endodontic treatment, the choice of methodology root canal is based on the specific clinical situation and the positive and negative aspects of the method of obturation. Thus, modern appliances for obturation require further improvement and selection procedure root canal should be made based on the clinical situation and taking into account the positive and negative aspects of the method of obturation. The use of methods of obturation using warmed gutta-percha can have complications in the form of periodontal tissue burns. Using low-temperature gutta-percha flow will help reduce the thermal load on the tooth and increase the working time, which is good to use in complex cases with thin curved root canals, as well as for inexperienced physicians. Application of this technique, dentists have to be experience and manual skills unacceptable. Before proceeding to clinical application should be thoroughly master the theoretical basis and take a master class on extracted teeth.
