introduction: transportation is an important iatrogenic endodontic error which might cause failure. this study evaluated the canal transportation caused by neoniti and protaper instruments, using cone-beam computed tomography (cbct) cross sections. methods and materials: this in vitro experimental study was performed on 40 mesiobuccal roots of maxillary first molars. the teeth were scanned with...

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...

Aims and Objectives Root canal preparation and obturation are of great importance in endodontics. Its purpose is to eliminate pulpal and periradicular disease. The aim of this study was to compare coronal bacterial microleakage in prepared root canals using Neoniti A1 and Reciproc files that obturated with lateral compaction, single cone gutta-percha, and hybrid (tapered cone/lateral compaction...

Introduction: The aim of this study was to determine the incidence of dentinal cracks in the  mesial root of maxillary molar during canal preparation using Neoniti system in different torque settings. Materials &Methods: In this in-vitro study, 60 maxillary molars extracted for various reasons were selected. The teeth were divided into 4 groups: one group(n=15) without preparation was con...

A glide path file may contribute to extruding contaminated debris during the first treatment phase. Using rotary techniques rather than manually operated instruments is thought decrease amount of extruded and hence post-operative pain levels. Aim: To compare effect using Neoniti GPS rotating in comparison manual stainless-steel K-files on pain, asymptomatic nonvital mandibular molars. Methods: ...
