مقدمه : آماده سازی کانال ریشه دندان یکی از مهمترین مراحل در طی درمان کانال ریشه می باشد، با توجه به اینکه کاهش نقص و شکست در فایل ها سبب موفقیت بیشتر در درمان ریشه دندان می شود. هدف از این مطالعه بررسی مقایسه ای نقص و شکست در فایل های rotary و reciproc در کانال های ریشه دندان با انحنای شدید می باشد. مواد و روش ها: در این مطالعه آزمایشگاهی 60کانال مزیال دندان های مولر انسانی با اپکس بسته و انحنا...
The aim of this study was to evaluate the preparation time and the amounts of apically extruded debris and irrigant using different nickel-titanium instrumentation systems. Forty-five extracted single-rooted mandibular premolar teeth were selected and divided into three groups. The root canals were instrumented according to the manufacturers' instructions, using a reciprocating single-file syst...
canals prepared with different enlargements using single-file reciprocating systems (Reciproc and WaveOne) and a conventional multi-file rotary (BioRaCe) system by microcomputed tomographic analysis. Thirty mesial roots of mandibular molars with moderate curvature (10° to 20°) presenting a type II Vertucci canal configuration and similar internal volume were chosen and scanned at an isotropic r...
Cyclic fatigue resistance of ProTaper Universal, Twisted File Adaptive, Reciproc and WaveOne systems
Background and Aims: Cleaning and shaping is one of the most important stages in endodontic treatment. Single-file systems save time and reduce the risk of transmission of pathogens. This in vitro study was aimed to compare the rate of canal transportation after the preparation of the stimulated resin root canal with two single-file systems, namely Waveone and Reciproc. Materials and Met...
WaveOne Gold, ProTaper Reciproc Blue, Next, and files were selected to compare the phase transformation behaviors mechanical properties of nickel-titanium (NiTi) rotary after gold heat blue treatments. The reverse finishing point temperatures Next higher than those other two instruments investigated. At a deflection 0.5 mm, loads significantly varied except for Gold. 3.0 Blue Gold compared ProT...
BACKGROUND Electronic apex locators (EALs) are modern devices used to determine the working length during root canal preparation. The newest endodontic motors provide an integrated EAL with auto-stop function to prevent instrumentation beyond the predefined working length during rotary root canal preparation. The aim of this study was to compare the accuracy of the auto-stop function of the VDW...
