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 ...
Effect of ProTaper and Reciproc preparation and gutta-percha cone on cold lateral compaction
(2016-09-01)
Context: The effectiveness of cold lateral compaction depends on the root canal preparation and used gutta-percha cone. Aims: The aim of this study is to evaluate finger spreader penetration into root canals prepared with ...

(Universidade de São Paulo (USP), Faculdade de Odontologia de Bauru, 2014-05-01)
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 ...
Effectiveness of Self-Adjusting File, XP-endo Finisher, and passive ultrasonic irrigation in bacterial root canal control
(2018-01-01)
Objective: To evaluate the effectiveness of complementary protocols of sanitization in decontamination of infected root canals. Methods: A total of 50 single-rooted maxilary anterior human teeth were selected. The crowns ...

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 ...
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. ...
