Transportation Assessment in Simulated Curved Canals after preparation with Twisted File Adaptive and BT-Race instruments.

Background: This study compared the incidence of deviation along curved canals after preparation with two nickel-titanium (NiTi) rotary systems, Twisted File Adaptive and BT-RaCe.

Material And Methods: Forty resin training blocks with curved canals were filled with ink and divided into two groups according to the instrumentation technique. Preinstrumentation images were acquired by using a stereomicroscope.

Efficacy of a new Activation Device in Irrigant Penetration Into Simulated Lateral Canals.

Objective: The aim of the present study was to compare the effects of EasyClean (EC) on irrigant delivery into simulated lateral canals using an artificial closed canal system. Passive ultrasonic irrigation (PUI) was used as a reference technique for comparison.

Methods: Forty simulated curved root canals manufactured in transparent resin and with simulated lateral canals were instrumented with Reciproc R40 files and randomly assigned to four groups (n=10) according to the irrigant activation technique: PUI group, ECrec group (EC used in reciprocating motion), ECrot group (EC used in rotary motion), and control group (no activation performed).

The Effect of Sodium Hypochlorite and Chlorhexidine as Irrigant Solutions for Root Canal Disinfection: A Systematic Review of Clinical Trials.

Introduction: This systematic review aimed to compare the effectiveness of sodium hypochlorite and chlorhexidine for root canal disinfection during root canal therapy.

Methods: A literature search for clinical trials was made on the PubMed (MEDLINE), Web of Knowledge, SCOPUS, and Science Direct databases and in the reference lists of the identified articles up to January 2015. Quality assessment of the selected studies was performed according to the Consolidated Standards of Reporting Trials statement.

Comparison of the effects of TripleGates and Gates-Glidden burs on cervical dentin thickness and root canal area by using cone beam computed tomography.

Unlabelled: The search for new instruments to promote an appropriate cervical preparation has led to the development of new rotary instruments such as TripleGates. However, to the best of the authors' knowledge, there is no study evaluating TripleGates effect on the "risk zone" of mandibular molars.

Objectives: The aim of this study was to evaluate the effects of a crown-down sequence of Gates-Glidden and TripleGates burs on the remaining cervical dentin thickness and the total amount of dentin removed from the root canals during the instrumentation by using cone beam computed tomography.

Chlorhexidine gel associated with papain in pulp tissue dissolution.

Objectives: This study aimed to evaluate the capacity of 2% chlorhexidine gel associated with 8% papain gel in comparison with 5.25% sodium hypochlorite in bovine pulp tissue dissolution.

Materials And Methods: Ninety bovine pulps of standardized sizes were used and fragmented into 5-mm sizes.

Sealing ability promoted by three different endodontic sealers.

Introduction: The aim of this study was to evaluate the apical and coronal seal of endodontic filling promoted by the combined use of Sealer 26/gutta-percha, Endofill/gutta-percha and Resilon/ Epiphany.

Materials And Methods: A total of 38 extracted human canine teeth were selected; 10 teeth for each test group and 4 for each control group. After conducting conventional endodontic treatment, the teeth were immersed in saline solution for thirty days, and subsequently sealed and stored in India ink for seven days.
