1. Effect of passive ultrasonic activation on microorganisms in primary root canal infection: a randomized clinical trial
Abstract Objective: This clinical study sought to evaluate the effectiveness of passive ultrasonic activation (PUA) in eliminating microorganisms in primary endodontic infection (PEI) after instrumentation of root canals using microbiological culture and checkerboard DNA-DNA hybridization. Methodology: Twenty root canals with PEI and apical periodontitis w

2. Análise da desinfecção apical do canal radicular preparado em três diferentes comprimentos de trabalho, utilizando movimento rotatório contínuo ou reciprocante e duas substâncias irrigadoras: estudo in vitro
Resumo Introdução O preparo do canal radicular, em especial o terço apical, é fundamental para o sucesso da terapia endodôntica, pois abriga o forame radicular, local que comunica o endodonto com os tecidos perirradiculares. Objetivo A presente pesquisa avaliou a contaminação do terço apical após a instrumentação de canais radiculares em três c

3. Effect of EDTA and QMIX Ultrasonic Activation on the Reduction of Microorganisms and Endotoxins in Ex Vivo Human Root Canals
Resumo O presente estudo objetivou comparar a eficácia do QMiX e do EDTA 17% associado à irrigação ultrassônica passiva (PUI) ou agitação manual (MA) na redução de E. faecalis, E. coli e LPS de canais radiculares. Quarenta dentes humanos unirradiculares foram divididos aleatoriamente em quatro grupos (n = 10), de acordo com o protocolo final de irri

4. Comparison of two rotary systems in bacteria/lps removal from endodontic infections: randomized clinical trial
Abstract: This clinical study compared the effectiveness of two rotary systems: HyFlex CM (Coltene-Whaledent, Altstetten, Switzerland) and ProTaper Next (Dentsply Sirona, Ballaigues, Switzerland) on the removal of cultivable bacteria and endotoxins from primarily infected root canals. This study was designed as a randomized single-blinded, 2-arm, clinical tr

5. Effectiveness of XP-Endo Finisher in the reduction of bacterial load in oval-shaped root canals
Abstract: This study investigated the effectiveness of XP-Endo Finisher (XPF) associated with XP-Endo Shaper (XPS) or Reciproc Blue (RB) files in reducing bacterial load in oval-shaped root canals (RC) during chemomechanical preparation (CMP) using 0.9% saline solution (NaCl) or 2.5% sodium hypochlorite (NaOCl). Eighty mandibular incisors with single oval-sh

6. Influence of chlorhexidine and zinc oxide in calcium hydroxide pastes on pH changes in external root surface
Abstract The objective of this study was to assess the influence of chlorhexidine (liquid and gel) and zinc oxide in calcium hydroxide (CH) pastes on root pH in simulated external resorption. One hundred human anterior teeth with a single root canal were selected. After decoronation and root canal instrumentation, the specimens were divided into 4 experiment

7. Ultrasonic tips as an auxiliary method for the instrumentation of oval-shaped root canals
Abstract To evaluate the influence of novel ultrasonic tips as an auxiliary method for the rotary preparation of flattened/oval-shaped canals. Forty-five mandibular incisors were selected and divided into one of three experimental groups (n = 15): Group PFCP – ProDesign Logic 25/.05 + Flatsonic + Clearsonic + Prodesign Logic 40/.01; Group FCP – Flatsonic

8. Nickel–titanium instruments in endodontics: a concise review of the state of the art
Abstract: The introduction of automated instrumentation in endodontics represented a major advance in progress for this specialty, with improvements in the quality and predictability of root canal preparation and a significant reduction in procedural errors. In recent years, endodontic instruments have undergone a series of changes brought about by modificat

9. Debris extrusion and foraminal deformation produced by reciprocating instruments made of thermally treated NiTi wires
Abstract Objective To evaluate the amount of apically extruded debris, percentage of foraminal enlargement and apical foramen (AF) deformation that occurred during root canal preparation with different reciprocation systems: Reciproc, WaveOne (M-Wire), and ProDesign R (Shape Memory Technology Wire) at two different working lengths (WLs): 0.0 and 1.0 mm beyo

10. Factors affecting the periapical healing process of endodontically treated teeth
Abstract Tissue repair is an essential process that reestablishes tissue integrity and regular function. Nevertheless, different therapeutic factors and clinical conditions may interfere in this process of periapical healing. This review aims to discuss the important therapeutic factors associated with the clinical protocol used during root canal treatment a
