1. 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

2. Evaluation of the sealing ability of different root canal sealers: a combined SEM and micro-CT study
Abstract Objective: The purpose of this study was to analyze the ability of multiple compounds to seal the dental tubules using scanning electron microscopy (SEM) and micro-computed tomogra-phy (micro-CT). Material and Methods: Twenty-four single-root human mandibular premolars were selected and instrumented with nickel-titanium rotary file and the final f

3. Root filling bond strength using reciprocating file-matched single-cones with different sealers
Abstract The aim of the present study was to evaluate the bond strength (BS) of root canal fillings to root dentin using the reciprocating file-matched single-cone or lateral compaction techniques with resin-based and calcium-silicate-based sealers. Maxillary canine roots were prepared and filled using one of the following approaches: Reciproc R40 file and R

4. Evaluation of three instrumentation techniques at the precision of apical stop and apical sealing of obturation
OBJECTIVE: The aim of this study was to investigate the ability of two NiTi rotary apical preparation techniques used with an electronic apex locator-integrated endodontic motor and a manual technique to create an apical stop at a predetermined level (0.5 mm short of the apical foramen) in teeth with disrupted apical constriction, and to evaluate microleakag

5. Avaliação do efeito de duas técnicas de instrumentação na zona de risco de molares inferiores curvos por microtomografia computadorizada e análise de imagens / Effect of two instrumentation techniques in the risk zone of curved molars by microcomputed tomography and image analysis
O objetivo deste estudo foi avaliar a espessura mínima radicular remanescente e o desgaste porcentual do terço cervical em raízes mesiais de molares inferiores, após a instrumentação com as técnicas ProTaper Universal e Lima única F2. Foram obtidos 100 primeiros molares inferiores com raízes completamente separadas. Desse total, foram selecionados e

6. Comparative study between Cone-Beam volumetric tomography and periapical radiographs on helping Endodontic diagnosis / ESTUDO COMPARATIVO ENTRE A TOMOGRAFIA VOLUMÉTRICA CONE-BEAM E RADIOGRAFIAS PERIAPICAIS NO AUXÍLIO AO DIAGNÓSTICO ENDODÔNTICO
This study aimed to analyze and compare volumetric tomography Cone- Beam and periapical examination, by technique of Clark, identifying accidents and endodontic complications, which were simulated, for endodontic interest. Sixteen human teeth from three human jaws were submitted to preparation of 20 changes/injuries in order to simulate situations that can l

7. Evaluation of the apical infiltration after root canal disruption and obturation
The aim of this study was to evaluate two root canal filling techniques used in teeth that had their apical foramen disrupted and compare the apical infiltration with an ideal clinical situation. Twenty-seven freshly extracted single-rooted teeth were selected and radiographed to confirm the existence of a single and straight root canal. The crowns were remo

8. In vitro sealing ability of white and gray mineral trioxide aggregate (MTA) and white Portland cement used as apical plugs
This study evaluated the sealing ability of apical plugs made of white and gray MTA-Angelus® and white Portland cement placed via the root canal and having different thicknesses (2, 5 and 7 mm). Ninety extracted human single-rooted teeth were instrumented using a size 40 K-file to standardize the foraminal opening by the stepback technique. The teeth were a

9. Selectivity of calcium channels in rat uterine smooth muscle: interactions between sodium, calcium and barium ions.
1. Action potentials and membrane currents were recorded by means of a double sucrose-gap technique from Cs-loaded strips from pregnant rats superfused in Ca-free EGTA-containing solutions. 2. When external Ca was reduced below 1 microM in the presence of 1 mM-EGTA, step depolarizations from a holding potential close to the normal resting potential produced
