Effect of Different Tapered Gutta Percha Cones in Apical Microleakage of Human Root Canal Obturation
Background and purpose: Gutta-percha is generally accepted as the main canal filler. Standard gutta-percha cones are available in 2-10% tapers. The purpose of this study was to compare apical microleakage of canals obturated with different tapers of gutta-percha, using the protein penetration technique. Materials and methods: In this study, 96 maxillary anterior teeth were selected and were pr...
متن کاملThe Role of Root Canal Preparation on Apical Geometry: A Review of the Literature
The amounts of apical enlargement have been a controversial issue for a long time. The enlargement of the apical part of the canal may severely impact the endodontic prognosis. Enlargement of the apical portion to a larger size may negatively affect the ability to control the filling material during root canal obturation. In addition, an open-apex increases the risk for overfilling which has be...
متن کاملApical Microleakage in Root Canals Containing Broken Rotary Instruments
INTRODUCTION Broken instruments in root canals complicate routine endodontic treatment. This study aimed to compare apical microleakage in root canals containing broken rotary instruments filled with mineral trioxide aggregate (MTA), calcium-enriched mixture (CEM) cement, laterally compacted gutta-percha and injected gutta-percha. METHODS AND MATERIALS In this in vitro, experimental study, 80...
متن کاملComparison of two rotary systems in root canal preparation regarding disinfection.
INTRODUCTION The aim of the present study was to determine the disinfection of preparations carried out by using the Protaper or MTwo system in canals infected with Enterococcus faecalis. METHODS Twenty-eight distobuccal canals of upper molars were used, in which the canals were sterilized after being enlarged to #20 file and then contaminated with an inoculation of a culture of E. faecalis. ...
متن کاملEffect 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...
