The influence of the apical limit of root canal preparation on apical foramen transportation (laboratory study)
Objective: This study was conducted to evaluate the effect of apical terminus location of the root canal preparation on apical transportation in vitro. Materials and Method: Thirty extracted human maxillary first molars with mature apices were used. The mesiobuccal root of each tooth was mounted in a square piece of silicone leaving foramen on top. The specimens were randomly divided into 3 gro...
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 کاملEffect 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 کاملEx-vivo Apical Seal Comparison of Root Canal Obturation Using MTA Fillapex Versus MTA Orthograde
Introduction: Mineral trioxide aggregate (MTA) as an alternative material to gutta-percha for obturation of root canal in special cases has several drawbacks. The purpose of this study was to compare the apical sealing ability of a new MTA-based sealer versus MTA. Materials and Methods: A total of 36 canals of extracted maxillary central incisors were instrumented and randomly divided into 3...
متن کاملApical termination of root canal procedures—ambiguity or disambiguation?
The issues of working length determination, its apical extent, and the position of the final root canal filling have been controversial, as differing points of view have existed between the biologically based and clinically based endodontic gurus regarding this concept for decades. Coupled with the following issues, it has become somewhat of an empirical bastion for clinicians, especially those...
