Canal preparation and filling techniques do not influence the fracture resistance of extensively damaged teeth
(2014-01-01)
The purpose of this study was to assess the fracture resistance of extensively damaged teeth after two root canal preparation techniques (hand and rotary files) and after two filling techniques (active and passive compaction). ...
Effect of obturation technique using a new bioceramic sealer on the presence of voids in flattened root canals
(2021-01-01)
The aim of this study was to evaluate the filling ability of a new ready-to-use calcium silicate-based sealer using thermoplastic or single-cone technique in flattened root canals. Twenty-four flattened distal canals of ...
In vitro evaluation of root canal preparation using oscillatory and rotary systems in flattened root canals
(Universidade de São Paulo (USP), Faculdade de Odontologia de Bauru, 2007-01-01)
Objective: the aim of this study was to evaluate the biomechanical preparation of flattened root canals using the following systems: Endo-Eze AET stainless steel oscillatory instruments (Ultradent) and RaCe rotary NiTi ...
Assessment of the apical seal of root canals using different filling techniques.
(2009-12-01)
The aim of this study was to investigate the apical leakage of roots filled by three different gutta-percha techniques: lateral condensation, Tagger's hybrid and E&Q Master. Forty-two extracted single-rooted teeth were ...
CT study of the performance of reciprocating and oscillatory motions in flattened root canal areas
(Sociedade Brasileira de Pesquisa Odontológica - SBPqO, 2015)
Root canal preparation is an important step in endodontic treatment. The anatomical complexity of the middle third of the root compromises the effective cleaning of this area. Thus, advances have been made in instrumentation ...
Periapical tissue healing after post space preparation with or without use of a protection plug and root canal exposure to the oral environment. Study in dogs
(2007-12-01)
The purpose of this study was to evaluate the influence of coronal leakage on the healing of dogs' periapical tissues after root canal filling, post space preparation and protection or not with a temporary sealer plug. ...
Comparison of the effectiveness of 3 irrigation devices for the cleaning of root canal walls instrumented with oscillatory and rotary techniques
(2015-01-01)
In this study, scanning electron microscopy (SEM) was used to evaluate the smear layer removal of 3 irrigation devices. The study hypothesis was that more contemporary side-vented needles and brush-covered needles are more ...
Effect of the root canal final rinse protocols on the debris and smear layer removal and on the push-out strength of an epoxy-based sealer
(2013-05-01)
The aim of the present study was to evaluate the efficacy of QMiX, SmearClear, and 17% EDTA for the debris and smear layer removal from the root canal and its effects on the push-out bond strength of an epoxy-based sealer ...
Apical leakage following root canal dressing with calcium hydroxide.
(1995-12-01)
The purpose of this study was to analyse the apical leakage in teeth filled by the lateral condensation technique following medication with calcium hydroxide. One hundred and twenty extracted human teeth were biomechanically ...
