Impact of Metallurgical Features on the Cyclic and Torsional Properties of Five Reciprocating Instruments Manufactured With Blue Thermal Treatment
This study evaluated the metallurgical and mechanical properties of five reciprocating instruments with blue thermal treatment. A total of 200 NiTi rotary instruments (25.08 and 40.06) were used: Reciproc Blue (RB), RC Blue (RCB), Only One File (OOF), Blue T (BT), and Rec Blue File (RBF). The cyclic...

Impact of Metallurgical Features on the Cyclic and Torsional Properties of Five Reciprocating Instruments Manufactured With Blue Thermal Treatmentcyclic fatiguedifferential scanning calorimetrynickel-titanium alloytorsional strengthX-ray diffractionThis study evaluated the metallurgical and mechanical properties of five reciprocating instruments with blue thermal treatment. A total of 200 NiTi rotary instruments (25.08 and 40.06) were used: Reciproc Blue (RB), RC Blue (RCB), Only One File (OOF), Blue T (BT), and Rec Blue File (RBF). The cyclic fatigue test was performed in an artificial canal with a curvature angle of 60° and a curvature radius of 5 mm (n = 20). The time to fracture was recorded (TTF). The torsional test was performed to evaluate the maximum torsional strength and angular deflection of the instrument's tip (n = 20). Differential Scanning Calorimetry (DSC) and x-ray diffractometry (XRD) were used to assess the metallurgical features. ANOVA and Tukey tests were used for statistical comparison. The OOF 25.08 and 40.06 exhibited higher TTF than the other groups (p < 0.05). There was no significant difference among OOF, RBF, and RB 25.08 regarding the torsional strength (p > 0.05). RCB 40.06 had the lowest torsional strength (p > 0.05). DSC analysis indicated that OOF had higher austenite start and finishing temperatures. XRD analysis revealed that the 25.08 and 40.06 instruments of OOF had the highest peaks of the martensite phase. Variations in metallurgical phases and temperature transformations affected the mechanical properties of the instruments.Department of Operative Dentistry Endodontics and Dental Materials Bauru School of Dentistry University of São Paulo – USPDentistry Program at Health Sciences School Universidad Peruana de Ciencias Aplicadas (UPC)Private Practice in EndodonticsSão Paulo State University (UNESP) School of Sciences Campus Bauru Laboratory of Anelasticity and BiomaterialsSão Paulo State University (UNESP) School of Sciences Campus Bauru Laboratory of Anelasticity and BiomaterialsUniversidade de São Paulo (USP)Universidad Peruana de Ciencias Aplicadas (UPC)Private Practice in EndodonticsUniversidade Estadual Paulista (UNESP)2025-04-29T18:06:51Z2025-01-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttp://dx.doi.org/10.1002/jemt.24840Microscopy Research and Technique.1097-00291059-910Xhttps://hdl.handle.net/11449/29752010.1002/jemt.248402-s2.0-85219619170Scopusreponame:Repositório Institucional da UNESPinstname:Universidade Estadual Paulista (UNESP)instacron:UNESPengMicroscopy Research and Techniqueinfo:eu-repo/semantics/openAccessTeves Cordova, Abel Victor isidroAlcalde, Murilo PrioriVivan, Rodrigo RicciZevallos Quiroz, Cesar AndreGuzmán, Hubert PonceCalefi, Pedro SouzaPinto, Bruna Oliveira [UNESP]Correa, Diego Rafael Nespeque [UNESP]Grandini, Carlos Roberto [UNESP]Duarte, Marco Antonio Hungaro2025-06-24T06:13:56Zoai:repositorio.unesp.br:11449/297520Repositório InstitucionalPUBhttp://repositorio.unesp.br/oai/requestrepositoriounesp@unesp.bropendoar:29462025-06-24T06:13:56Repositório Institucional da UNESP - Universidade Estadual Paulista (UNESP)false |
