Mechanical and Metallurgical Properties of Various Nickel-Titanium Rotary Instruments
The aim of this study was to investigate the effect of thermomechanical treatment on mechanical and metallurgical properties of nickel-titanium (NiTi) rotary instruments. Eight kinds of NiTi rotary instruments with sizes of ISO #25 were selected: ProFile, K3, and One Shape for the conventional alloy; ProTaper NEXT, Reciproc, and WaveOne for the M-wire alloy; HyFlex CM for the controlled memory-...
متن کاملHow to improve writing English articles
Introduction: One of the sections that readily captures the attention of readers of scientific articles is the title, but unfortunately, some authors, although being competent in writing the main content of the article, and considering the matters related to the writing style, mostly lack the skill required to couch the title in an attractive way. Methods: In this article, using three decades ...
متن کاملHyFlex nickel-titanium rotary instruments after clinical use: metallurgical properties.
AIM To analyse the type and location of defects in HyFlex CM instruments after clinical use in a graduate endodontic programme and to examine the impact of clinical use on their metallurgical properties. METHODOLOGY A total of 468 HyFlex CM instruments discarded from a graduate endodontic programme were collected after use in three teeth. The incidence and type of instrument defects were anal...
متن کاملHow to improve English articles writing methods
Introduction: Today, English and its use as an international language is agreed upon by all, and a wealth of scientific articles written every day in the whole world is in English. The purpose of this study is to project some commonly used grammatical points that native speakers of Persian, unfortunately, do not follow or do not have adequate knowledge to use when writing in English, but this s...
متن کاملCorrosion of Ni-Ti Rotary Instruments: A Review
The nickel-titanium (Ni-Ti) alloys used in endodontics contain 56% Ni and 44% Ti. The 2 unique features related to clinical dentistry (i.e., shape memory effect and superelasticity) are due to the transition from austenite to martensite in Ni-Ti alloy. When a superelastic Ni-Ti alloy undergoes a low tensile loading, normal elastic behavior occurs. In fact, at higher tensile loads, the elastic s...
