The present research analyzed the reciprocating instrumentation associated to chlorhexidine (CHX) substantivity as its correlation with E. faecalis viability in ex vivo root canals. Eighty extracted single-rooted human teeth were used, being 40 high-performance liquid chromatography (HPLC) and confocal laser scanning microscopy (CLSM). In both, decoronated cervical third was prepared. CLSM anal...

BACKGROUND Spinal cord injury patients walk with a flexed trunk when using reciprocating gait orthoses. Reduction of trunk flexion during ambulation may produce an improvement in gait parameters for reciprocating gait orthosis users. OBJECTIVES To investigate the effect on kinematics and temporal-spatial parameters when spinal cord injury patients ambulate with an advanced reciprocating gait ...

Objective:
 To assess the life of two different rotary nickel-titanium (NiTi) instruments in curved canals with complete protocol, by using 360°rotation motion and reciprocating motion.
 Materials Methods:
 About one hundred seventy extracted maxillary mandibular molars were taken from which root selected randomly divided 2 groups, for analyzing number uses files. One prepared Hy...

This study aimed to compare the intracanal lateral force and cutting efficiency associated with two engine-driven nickel-titanium (NiTi) systems during root canal shaping. Bovine single-rooted teeth models were assembled a custom-made splitting measuring platform while being endodontically treated rotary (ProTaper Gold [PTG]) or reciprocal (WaveOne [WOG]) by clinicians. The test was run for eac...

This systematic review was registered in PROSPERO (CRD42017075917) and aimed to investigate whether the available clinical evidence supports hypothesis that reciprocating motion results a lower incidence of nickel-titanium files fracture compared continuous rotation. Clinical studies reported engine-driven were included. The main exposure kinematics, primary outcome fracture. overall 2.27%, wit...

Amaç: Endodonti alanında resiprokal hareket yapan tek eğe sistemleri son yıllarda popüler hâle gelmiştir. Apikalden taşan debrisin miktarı, kullanılan sistemlerinin tasarımlarına göre çeşitlilik gösterebilmektedir. Bu in vitro çalışmanın amacı, resiprokasyon hareketi ile çalışan Scope Reciproc, T-Endo MUST, EndoART Reciproc ve WaveOne Gold sistemlerinin, kök kanal preparasyonu sırasında apikald...

During the electrophysiologic study of 435 patients referred for evaluation of WolffParkinson-White syndrome, 42 (10%) had preexcited reciprocating tachycardia (defined as a macroreentrant tachycardia that used an accessory atrioventricular [AV] pathway for antegrade conduction). The ages of the patients ranged from 9 to 67 years (27 + 14). Thirty-three were male patients, nine female, and eigh...

OBJECTIVES The aim was to compare the shaping ability of WaveOne reciprocating files with or without glide path in simulated curved S-shaped root canals. MATERIALS AND METHODS Forty ISO #15, 0.02 taper, clear resin Endo Training Bloc-S blocks were studied. The simulated curved S-shaped canals were dyed using ink, preinstrumentation images were scanned, and resin blocks were prepared and divid...

INTRODUCTION This study evaluated the influence of glide path on canal curvature and axis modification after instrumentation with WaveOne Primary reciprocating files. METHODS Thirty ISO 15, 0.02 taper Endo Training Blocks were used. In group 1, glide path was created with PathFile 1, 2, and 3 at working length, whereas in group 2, glide path was not performed. In both groups, canals were shap...
