Micro-Computed Tomographic Evaluation of Shaping Ability and Dentinal Microcracks Formation After Using New Heat-Treated Nickel-Titanium Systems
Author(s): Abdulhakim Al Gamdi and Shibu Thomas Mathew*
Introduction: This ex vivo study aims to evaluate the shaping ability and dentine microcracks formation after using four different heat-treated files, EdgeTaper PlatinumTM, ProTaper GoldTM, Reciproc® Blue, and EdgeOne FireTM Files. Methods: Forty extracted mandibular premolars were randomly selected. Samples were decoronated at 17mm from the apex with water cooling. Bruker© Skyscanner scanned the canal before and after instrumentation. For each group (DataViewer program version 1.5.6.2, Bruker©micro-CT), the manufacturer's evaluation software calculated the percentage rate and morphometric measurements of the percentage of walls untreated. Results: 65% continuous and 60% reciprocating files showed Type II defect in the apical third. The reciprocating motion files (Reciproc®Blue and.. Read More»
