Extrusion apical de detritus durante el tratamiento endodóntico [PDF]

, 2008
The authors made a literature review about the causes of the apical extrusion of debris, during endodontic treatment. In the root canal instrumentation there is always, besides the strict control of the working lenght, the possibility that dentin chips ...

Apical extrusion of root canal filling material during the removal of gutta-percha and resilon [PDF]

Stomatološki glasnik Srbije, 2020
Introduction Root canal filling material may be extruded during retreatment through the apical foramen and cause flare-up or chronic infection. The aim of this study was to compare the apical extrusion of gutta-percha and resilon filling materials during

The effect of pressure and temperature variations on the FEM prediction of deformation during extrusion [PDF]

, 2005
The extrusion process is complex, involving interaction between the process variables and the material’s high temperature properties and is typically conducted at relatively high temperatures because the lower flow stress of the material permits larger ...

Comparative evaluation of extrusion of apical debris in primary anterior teeth using two different rotary systems and hand files: An In Vitro study

Contemporary Clinical Dentistry, 2019
Background: The success of endodontic treatment depends on the chemomechanical preparation of the tooth. However, the debris produced during canal preparation may extrude through the apical foramen causing postoperative complications.

Apical Extrusion of Intracanal Bacteria with Single File and Multifile Rotary Instrumentation Systems. [PDF]

J Int Soc Prev Community Dent, 2017
Instrumentation techniques may cause extrusion of microorganisms and their products into the periapical region resulting inflammation and treatment failure. The aim of this ex vivo study was comparing the apical bacterial extrusion in canals prepared with single file versus multiple file rotary systems.Ninety-two human single-rooted mandibular first ...
