13. Comparison of debris extruded apically and working time used by ProTaper Universal rotary and ProTaper retreatment system during gutta-percha removal
OBJECTIVE: The aim of this study was to evaluate the in vitro action of ProTaper retreatment files and ProTaper Universal in the retreatment of mandibular premolars. MATERIAL AND METHODS: The amount of debris extruded apically was measured and the time to reach the working length and to complete the removal of gutta-percha was observed. Thirty teeth had thei

14. Retratamento endodôntico : uma revisão de literatura
Apesar dos avanços na área da endodontia há casos que resultam em fracasso. Frente ao insucesso, o retratamento endodôntico é uma alternativa de primeira escolha desde que sejam respeitadas as suas indicações e limitações. O estabelecimento da etiologia do insucesso é fundamental para programar o retratamento endodôntico da maneira mais adequada.

15. Comparative sem evaluation of three solvents used in endodontic retreatment: an ex vivo study
This study compared, by scanning electron microscopy (SEM), the efficacy of three solvents on the removal of filling materials from dentinal tubules during endodontic retreatment. Forty human maxillary canines with straight canals were prepared according to a crown-down technique and enlarged to a#30 apical file size, before obturation with gutta-percha and

16. "Estudo da remoção do material obturador utilizando o laser de diodo de 810nm" / Study of the removal of root canal filling materials using an 810nm diode laser.
The laser therapy is an excellent adjunct clinical procedure in endodontic treatment in order to improve the cleaning and disinfection of the root canal system; however few studies in the literature investigated the possible use of this new technology in the clinical situations of retreatment. The objective of this study was to evaluate in vitro the use of t

17. Avaliação dos tratamentos endodonticos realizados no curso de especialização da Faculdade de Odontologia de Piracicaba : UNICAMP de 1997 a 2001 / Evaluation of root canal treatments performed by post graduate students at the Dental School of Piracicaba - State University of Campinas from 1997 to 2001
The aim of this study was to evaluate the root canal treatments performed between 1997 and 2001 by post-graduate students in the Endodontics specialization course of the Dental School of Piracicaba, State University of Campinas, Piracicaba,SP, Brazil. Patients were recalled during 2003 and 2004 for clinical and radiographic examinations. Among 608 records of

18. EFETIVIDADE DO GLUCONATO DE CLOREXIDINA A 1% ASSOCIADO À PASTA DE HIDRÓXIDO DE CÁLCIO (CALEN), COMO MEDICAÇÃO INTRACANAL, NO COMBATE AO Enterococcus faecalis
This study investigated the occurrence of Enterococcus faecalis in clinical specimens obtained from 25 cases in which endodontic treatment failed and 10 cases of primary endodontic infection, both of which are associated with asymptomatic apical periodontitis. As well, in cases in which it was possible to recover this bacterium, the antibacterial actions of

19. "Quantificação, por diferentes métodos, de material obturador remanescente no interior de canais radiculares, após desobturação e repreparo" / Quantity, through different methods, of the remaining material, after deobstruction and re-instrumentation
The aim of the present study was to evaluate the effectiveness of computed tomography and cross section in quantifying the remaining filling material during retreatment. For that, 32 teeth were prepared, filled and after the period necessary to the sealer set, the specimens had their filling material removed and were reprepared. The amount of filling materia

20. Avaliação de resultados em microcirurgia endodontica utilizando ionomero resinoso como material retrobturador / Evaluation of endodontic surgeries performed using a surgical operation microscope and a resin ionomer as retrofilling material
Retrospective observations were made on the success rate of endodontic surgery with microsurgical techniques using the resin ionomer Geristore as root-end filling material. Seventy-six cases were treated by one surgeon between 1999 and 2003. For inclusion in this retrospective study, a follow-up examination at 12 months minimum was required. The radiographic

21. Avaliação comparativa da citotoxicidade in vitro dos solventes utilizados no retratamento endodôntico / Comparative evaluation in vitro of solvents citotoxicity used in endodontic retratament
SUMMARY The aim of this study was to compare in vitro solvents used in endodontic retreatment therapy: orange oil, eucalyptol, xylene, chloroform and halothane through cytotoxicity evaluation of each solvent in different final concentration and contact conditions to NIH 3T3 fibroblasts cells lines. The experiment was divided in four stages: stage 1- the solv

22. Biocompatibilidade de solventes utilizados no retratamento endodontico : estudo experimental em ratos
Re-treatment is the first option in case of failure of the endodontic therapy. To enable this process, it is essential to remove the pre-existing filling material of the root canal. The use of solvents facilitates this procedure and helps to avoid accidents. One of the properties required from these solvents is non-aggression to periapical tissues. The aim o
