13. Influence of solvents on the bond strength of resin sealer to intraradicular dentin after retreatment
Abstract This study evaluated the removal of filling material with ProTaper Universal Rotary Retreatment system (PTR) combined with solvents and the influence of solvents on the bond strength (PBS) of sealer to intraradicular dentin after canal reobturation. Roots were endodontically treated and distributed to five groups (n = 12). The control group was not

15. Safety and feasibility of radiofrequency ablation for treatment of Bosniak IV renal cysts
ABSTRACT Purpose To describe our initial experience with radiofrequency ablation (RFA) of Bosniak IV renal cysts. Materials and Methods From 2010 to 2014, 154 renal tumor cases were treated with percutaneous thermal ablation, of which 10 cases (6.4%) from nine patients were complex renal cysts and were treated with radiofrequency ablation. Results All

16. Efficacy of entecavir and tenofovir in chronic hepatitis B under treatment in the public health system in southern Brazil
There are about 350 million hepatitis B virus (HBV) carriers worldwide and chronic HBV is considered a major public health problem. The objective of the present study was to assess the effectiveness of the nucleos(t)ide analogues tenofovir (TDF) and entecavir (ETV) in the treatment of chronic HBV. A cross-sectional study was carried out from March-December 2

18. 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

19. 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

20. Orthodontic retreatment of a Class III patient with significant midline asymmetry and bilateral posterior crossbite
A mordida cruzada posterior pode causar sérios problemas funcionais em longo prazo, se não tratada precocemente. Porém, em alguns pacientes com idade mais avançada, ainda é possível realizar a disjunção palatina para corrigir essa condição. Assim sendo, o objetivo do presente caso é relatar a correção tardia de uma mordida cruzada posterior bila

21. 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

22. Effectiveness of rotatory and reciprocating movements in root canal filling material removal
The purpose of this study was to compare the efficacy of reciprocating and rotary techniques for removing gutta-percha and sealer from root canals. Forty straight and oval single-rooted premolars were prepared up to size 30, filled with gutta-percha and sealer, and then randomly allocated to two experimental retreatment groups: ProTaper Retreatment System (P

23. Comparison of different retreatment techniques and root canal sealers: a scanning electron microscopic study
The aim of this study was to evaluate the effectiveness of two retreatment techniques, in terms of the operating time and scanning electron microscopy (SEM) results, in removing three different root canal sealers from root canals that were previously filled with gutta-percha. Sixty extracted single-rooted human premolars were divided into three groups and fi

24. 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
