Shock of paradigms on the instrumentation of curved root canals.
This paper makes a practical analysis about the paradigm on the instrumentation of curved root canals. In Endodontics, a paradigm has been created. Theories and techniques for instrumentation of curved root canals state that the use of a #25 file in the apical portion fulfills all the requirements for cleaning and shaping of the root canal system. Every scientific theory or paradigm should be c...
متن کاملThe 'balanced force' concept for instrumentation of curved canals revisited.
The principal characteristics of K-type files are described and the succession of operations as prescribed by the 'balanced force' method of preparation of root canals, particularly curved root canals, examined. On the basis of a simple mathematical model, the motions of a file in a straight canal and in a curved canal are successively considered, and the merits of the recommended method highli...
متن کاملA comparison of sealer placement techniques in curved canals.
Sealer placement techniques have not been examined in teeth with curved canals prepared with Lightspeed instruments. Three traditional methods of placing sealer were studied, using 45 extracted human single-rooted teeth, divided into 3 groups of 15. Root canal preparations were made with Light-speed nickel-titanium, engine-driven instruments. AH26 sealer was applied with either K-file, lentulo ...
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 کاملShaping Ability of NiTi Rotary versus Stainless-Steel Hand Instruments in Curved Root Canals of Extracted Teeth
Introduction: The purpose of this in-vitro study was to compare shaping ability of NiTi rotary Mtwo and FlexMaster with stainless steel hand K-Flexofile in curved root canals of extracted teeth. Materials and Methods: Mesiobuccal canals of 45 mandibular molar teeth were balanced into three groups of 15 each, with respect to the Schneider angle, canal access angle, height, dis-tance and radiu...
