Laboratory study of the quality of root canal obturation in the application of various techniques of medical treatment

Relevance . Under study is based on the fact that every year number of patients with complicated forms caries increases, in addition, complexity a treatment manipulations, often leads to various errors and complications at all stages endodontic treatment. Aim To evaluate tightness root canal obturation depending selected technique antiseptic canals. Materials methods 40 teeth extracted due chronic periodontitis were studied. All divided into 4 equal groups method canals: traditional protocol using 3% NaOCl 17% EDTA solution; distilled water Er,Cr:YSGG wavelength 2780 nm 1 W; 1.5 LAI technique. specimens filled continuous wave gutta-percha Calamus Dual instrument (DentSplay Maillefer) AH+ epoxy sealer (DentSplay). The was assessed by scanning electron microscopy. Results Treatment W laser revealed most hermetic fit material walls, which confirmed absence voids between dentin, contrast samples treated medical for Conclusions inclusion complex will not only increase canal, but also success obturation, significantly reduce risk complications.
