Shaping Ability of NiTi Rotary versus Stainless-Steel Hand Instruments in Curved Root Canals of Extracted Teeth
Introduction: The purpose of this in-vitro study was to compare shaping ability of NiTi rotary Mtwo and FlexMaster with stainless steel hand K-Flexofile in curved root canals of extracted teeth. Materials and Methods: Mesiobuccal canals of 45 mandibular molar teeth were balanced into three groups of 15 each, with respect to the Schneider angle, canal access angle, height, dis-tance and radiu...
متن کاملShaping ability of NiTi rotary versus stainless steel hand instruments in simulated curved canals.
OBJECTIVES The purpose of this in-vitro study was to compare shaping ability of NiTi rotary Mtwo and FlexMaster with stainless steel hand K-Flexofile in simulated curved root canals. STUDY DESIGN Forty-five simulated canals in resin blocks were prepared with Mtwo, FlexMaster and stainless steel hand K-Flexofile (15 blocks in each group). Using pre- and post- instrumentation images, straighten...
متن کاملinfl uence of motion pattern on apical transportation and centering ability of waveone single-fi le technique in curved root canals
background: the aim of this study was to evaluate apical transportation and centering ability of single-fi le instruments, waveone primary, with full rotation versus reciprocation movement using cone-beam computed tomography (cbct) analysis in curved mesiobuccal (mb) root canal of human mandibular molars. materials and methods: thirty mb canals of mandibular molars were randomly divided into tw...
متن کاملCentering and transportation: in vitro evaluation of continuous and reciprocating systems in curved root canals
CONTEXT One of the goals of endodontic therapy is the shaping and cleaning of the root canal system. In recent years, there has been multiple systems instrumentation, and changes in their dynamics are central to maintain the original shape of the canal after preparation. AIMS The aim of this study was to evaluate centering and transportation in curved root canals after using ProTaper(®) and M...
متن کاملA comparison of the shaping ability of reciprocating NiTi instruments in simulated curved canals
OBJECTIVES The study was to compare the shaping ability of Reciproc (VDW) and WaveOne (Dentsply Maillefer) instruments compared with ProTaper, Profile and hand instrument during the preparation of simulated root canals. MATERIALS AND METHODS Five groups (n = 5) were established. Reciproc, WaveOne, ProTaper, Profile and K file (K-flexo file) were used to prepare the resin simulated canals. A s...
