1. Endodontic Retreatment Using a Single Instrument from four Nickel-Titanium Systems - A Micro-CT Study
Resumo Este estudo laboratorial avaliou por meio de micro-CT a eficiência do uso de um único instrumento de três sistemas rotatórios em retratamentos endodônticos, comparados a um instrumento único reciprocante. Sessenta caninos extraídos foram preparados usando o sistema ProTaper Universal (F2) e obturados. Após 30 dias de armazenamento a 37 ºC e 1

2. Does Endodontic Re-Treatment in Primary Teeth Increase the Functional Tooth Retention? A Clinical, Retrospective, University-Based Study
Abstract Objective: To investigate the longevity of endodontic treatments and the survival of endodontic re-treatments performed in primary teeth. Material and Methods: The sample included endodontic treatments and re-treatments conducted in anterior and posterior primary teeth without sedation or general anesthesia among children attending a university de

3. Unprepared root canal surface areas: causes, clinical implications, and therapeutic strategies
Abstract: Chemomechanical preparation is intended to clean, disinfect, and shape the root canal. This step is of utmost importance during treatment of infected teeth with apical periodontitis, because treatment outcome depends on how effectively the clinician eliminates bacteria, their products, and necrotic tissue that would serve as substrate for bacterial

4. Evaluation of the efficacy of filling material removal and re-filling after different retreatment procedures
Abstract This study analyzed the influence of different retreatment protocols on amount of remaining filling material and amount of new sealer after endodontic retreatment. Forty mandibular molars with curved mesial roots were prepared with ProTaper Universal system, and filled with AH Plus sealer mixed with 0.1% rhodamine B and gutta-percha. After 7 days, t

5. Regenerative Endodontic Treatment as a Retreatment Option for a Tooth with Open Apex - A Case Report
Abstract: Treatment of non-vital immature teeth with apical periodontitis has always been a challenge in Endodontics. Regenerative endodontic treatment (RET) has been successfully used for the management of these cases. The aim of this study is to present a case of RET used for the retreatment of a previously endodontically treated permanent tooth with an op

6. Enterococcus spp. isolated from root canals with persistent chronic apical periodontitis in a Chilean population
Abstract Aim: To isolate and identify in a Chilean population,Enterococcus spp. from root canals with persistent chronic apical periodontitis (CAP) and to investigate the potential correlation between the bacteria and the observed clinical features. Methods: Twenty patients with indication for endodontic retreatment due to persistent CAP were selected. Dat

7. Prevalence of Treponemaspp. in endodontic retreatment-resistant periapical lesions
This study investigated the presence of the Treponema species in longstanding endodontic retreatment-resistant lesions of teeth with apical periodontitis, the association of this species with clinical/radiographic features, and the association among the different target species. Microbial samples of apical lesions were collected from twenty-five adult patien

8. Endodontic filling removal procedure: an ex vivo comparative study between two rotary techniques
In this study, we compared the ex vivo removal capacity of two endodontic rotary techniques and determined whether there was a significant quantitative difference in residual material when comparing root thirds. Forty extracted molars were used. The palatal roots were selected, and the canals were prepared using a step-back technique and filled using a later

9. Interference of partial visual analysis of root filling quality and apical status on retreatment decisions
OBJECTIVE: The presence of periapical radiolucency has been used as a criterion for endodontic treatment failure. However, in addition to the inherent limitations of radiographic examinations, radiographic interpretations are extremely subjective. Thus, this study investigated the effect of partial analysis of root filling quality and periapical status on re

10. Retratamento endodôntico: casuística e comparação de dois métodos de diagnóstico por imagem / Endodontic retreatment: case studies and comparison of two methods of diagnosis by image
The radiographic test is an essential diagnosis component in the treatment of problems of endodontic origin. Despite the technical and scientific developments in endodontics, the number of endodontic retreatment continues high. In this scenario, Computerized Beam Cone Tomography (CBCT) is used to obtain three-dimensional images without distortions of structu

11. Efficacy of five rotary systems versus manual instrumentation during endodontic retreatment
O propósito deste estudo foi avaliar a eficiência dos instrumentos rotatórios ProFile, GT, ProTaper, Race e K3 comparados com limas K para a remoção do material obturador durante o retratamento. Sessenta pré-molares inferiores foram instrumentados com o sistema rotatório GT e obturados usando a técnica de compactação termomecânica de guta-percha c

12. Estudo retrospectivo dos tratamentos e reintervenções endodônticas / Retrospective study of endodontic treatment and retreatment
A proposta deste estudo foi avaliar o índice de sucesso e insucesso do tratamento endodôntico original realizado por um especialista. Um total de 1376 dentes foi examinado clínica e radiograficamente e os resultados analisados estatisticamente pelos testes exatos de Pearson ou Fisher e regressão logística multivariável. Todos os testes estatísticos fo
