Pplačių kanalų ir nesusiformavusių šaknų viršūnių pildymui naudojamų medžiagų ir metodų lyginamoji analizė

Dental practitioners providing endodontic treatment sometimes are encountered with cases (wide canal and open apex due to periapical resorption or immature root) that require particular materials and methods for obturation of root canals. The aim of this systematic review is to compare materials and techniques intended for obturation of wide canals and open apex. Materials and methods. Articles search was carried out in the three databases - Pubmed-Medline, Science Direct, Willey online library. Researchgate and Endoexperience sites were searched as well. After screening, full-text analysis of selected studies was done. Results. After full-text analysis 31 publications was included into the study. Most studies showed that bioceramic materials regarding their properties are intended to use for obturation of wide canals and open apices. Preference is based on properties of bioceramic material and on favorable treatment results. An apical “barrier” creation with different cements was evaluated as preferable method for obturation of wide canals and open apex. Techniques of filling of root canals differ according to authors and selected materials. Conclusions. Bioceramic cement is the material of choice for obturation of wide canals and open apex. Vertical condensation of particular cement and apical plug creation is widely used method for obturation of wide canals and open apex. 1. One or two steps obturation techniques are recommended
