Fracture strength of roots instrumented with three different single file systems in curved root canals
OBJECTIVE The aim of this study was to compare the fracture strength of roots instrumented with three different single file rotary systems in curved mesial root canals of maxillary molars. MATERIALS AND METHODS Curvatures of 25°-35° on mesial roots of 60 maxillary molar teeth were sectioned below the cementoenamel junction to obtain roots 11 mm in length. The roots were balanced with respect ...
متن کاملInfluence of cervical preflaring on apical transportation in curved root canals instrumented by reciprocating file systems
BACKGROUND The aim of this study was to evaluate the influence of cervical preflaring on apical transportation in curved root canals prepared using the Reciproc and WaveOne reciprocating file systems. METHODS Sixty curved canals were instrumented using Reciproc R25 and WaveOne Primary files, with and without preflaring (n = 15). A double-digital technique was used to digitally superimpose the...
متن کاملComparative evaluation of fracture and defect in reciproc and rotary files in severe curved root canals
Introduction: Root canal instrumentation is an important phase in root canal therapy. Since success in endodontic treatment depends on file defect and fracture, the aim of this study was to compare the evaluation of defect and fracture in rotary and reciproc files in severe curved root canals. Materials & Methods: In this experimental study, 60 mesial canals of human closed apex molars with ...
متن کاملDye diffusion in instrumented root canals irrigated with different solutions.
Success in endodontics depends largely on the activity of the irrigation solutions used during canal cleaning and shaping. Sometimes the irrigation solutions should act deep within the dentin, particularly in cases of chronic infectious lesions, in which it has been found that germs can lodge in the depths of the dentinal tubules. The aim of this study was to compare the penetration of methylen...
متن کاملGeometric analysis of root canals prepared by single twisted file in three different operation modes
OBJECTIVE The aim of this study was to evaluate and compare the effects of a single twisted file (TF) instrument in three different operation modes on the preparation of curved root canals in human molars and to explore a new possible method in canal shaping in the clinic setting. MATERIALS AND METHODS A total of 105 selected root canals with an angle of curvature ranging from 20° to 35° were...
