Comparison of cyclic fatigue and torsional resistance in reciprocating single-file systems and continuous rotary instrumentation systems.
As compared with continuous rotary systems, reciprocating motion is believed to increase the fatigue resistance of NiTi instruments. We compared the cyclic fatigue and torsional resistance of reciprocating single-file systems and continuous rotary instrumentation systems in simulated root canals. Eighty instruments from the ProTaper Universal, WaveOne, MTwo, and Reciproc systems (n = 20) were s...
متن کاملinvestigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances
در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
In vitro Evaluation of Cyclic Fatigue Resistance of Reciprocating and Rotary Single-file System
Aim: In vitro study evaluation of the cyclic fatigue resistance of reciprocating and rotary single-file system [Wave One Gold (WOG), Reciproc, Hyflex electrical discharge machining (EDM) file systems] utilizing cyclic fatigue testing device. Materials and methods: Three nickel–titanium rotary systems (Hyflex EDM size #25, 0.06 taper and Reciproc and WOG size #25, 0.06 taper) were used in this s...
متن کاملcomparison of cyclic fatigue resistance of five nickel titanium rotary file systems with different manufacturing techniques
objectives: the purpose of this study was to evaluate the resistance to fatigue failure of five different nickel-titanium rotary files in three different curved trajectories. materials and methods: a total of 150 neoniti a1, race 25.06, mtwo 25.06, twisted file 25.06 and protaper next x2 files with the tip size of 25 were tested (n=30 for each group). three groove types simulating curved canals...
متن کاملcomparison of apical extrusion of debris by using single-file, full-sequence rotary and reciprocating systems
objectives: during root canal preparation, apical extrusion of debris can cause inflammation, flare-ups, and delayed healing. therefore, instrumentation techniques that cause the least extrusion of debris are desirable. this study aimed to compare apical extrusion of debris by five single-file, full-sequence rotary and reciprocating systems. materials and methods: one hundred twenty human mandi...
