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 ...
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. ...
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 after root canal filling with an experimental calcium hydroxide gutta-percha point
(1996-12-01)
This study was an in vitro analysis of the apical seal of root canals filled with an experimental calcium hydroxide gutta-percha point. One hundred and ten recently extracted human permanent teeth with a single root were ...
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 ...
Influence of the type of vehicle and limit of obturation on apical and periapical tissue response in dogs' teeth after root canal filling with mineral trioxide aggregate
(Elsevier B.V., 2007-06-01)
The purpose of this study was to investigate the influence of the type of vehicle (distilled water or propyleneglycol) on the response of apical tissues of dogs' teeth after root canal filling with mineral trioxide aggregate ...
Performance of race instrumentation system in curved root canals: a comprehensive analysis by three study methods
(2013-08-20)
In this study, curved maxillary molar root canals were instrumented with RaCe rotary system to evaluate: 1. the occurrence of canal transportation using a radiographic platform; 2. the action of the instruments on the ...
Effect of root canal filling material and level of surgical injury on periodontal healing in dogs
(Munksgaard Int Publ Ltd, 1998-10-01)
Some divergencies in the literature about periodontal healing after surgical injury stimulated the development of this experiment. The root canals of dogs' teeth were negotiated and filled by the lateral condensation ...
Effect of filling technique and root canal area on the percentage of gutta-percha in laterally compacted root fillings
