Fracture Risk of Endodontic Files: Clinical Analysis of Reciproc and X1 Blue After Multiple Uses

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT This retrospective study assessed the fracture incidence of Reciproc R25 and X1 Blue 25.06 files after up to three uses in 1720 root canals (1620 teeth) treated by a specialist. A standardised protocol was followed for all procedures. Periapical radiographs with the fractured instrument were used to evaluate the fragment's location and size ...

Cyotoxicity of Etidronate as an Endodontic Chelator Against Periodontal Ligament Fibroblast

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT Etidronic acid (HEBP) causes fewer alterations in dentine and can be used mixed with sodium hypochlorite during root canal preparation. This study investigated the cytotoxicity effects of the HEDP and EDTA on human periodontal ligament fibroblast cells. Primary culture was established from human periodontal ligament tissue of one donor and was
