Effect of root canal preparation, type of endodontic post and mechanical cycling on root fracture strength
OBJECTIVE To evaluate the impact of the type of root canal preparation, intraradicular post and mechanical cycling on the fracture strength of roots. MATERIAL AND METHODS eighty human single rooted teeth were divided into 8 groups according to the instruments used for root canal preparation (manual or rotary instruments), the type of intraradicular post (fiber posts- FRC and cast post and cor...
متن کاملAssessment Using AutoCAD Software of the Preparation of Dentin Walls in Root Canals Produced by 4 Different Endodontic Instrument Systems
Objectives. To compare the effectiveness of four instrument systems for preparing oval root canals: manual instrumentation (Step-Back technique), ProTaper Universal, ProTaper Next, and Wave One. Material and Methods. For the purpose of this assessment, 60 teeth extracted for orthodontic or periodontal reasons, specifically canines and premolars with full coronal and root anatomy, were used and ...
متن کاملEffect of endodontic irrigating solutions on the microhardness and roughness of root canal dentin: an in vitro study.
CONTEXT To evaluate the effect of widely used endodontic irrigating solutions on root dentin microhardness and surface roughness. MATERIALS AND METHODS One hundred twenty, non-carious extracted human permanent incisor teeth were selected. The crowns of the teeth were sectioned and the roots were separated longitudinally to get 240 specimens. These specimens were then divided into six groups a...
متن کاملTemperature increases on the external root surface during endodontic treatment using single file systems.
AIMS The aim of this study is to evaluate increases in temperature on the external root surface during endodontic treatment with different rotary systems. MATERIALS AND METHODS Fifty human mandibular incisors with a single root canal were selected. All root canals were instrumented using a size 20 Hedstrom file, and the canals were irrigated with 5% sodium hypochlorite solution. The samples w...
متن کاملEffect of different torques on dentinal crack formation following canal preparation using neoniti rotary system
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...
