To evaluate the radiopacity, setting time, pH level, calcium ion release and solubility of white mineral trioxide aggregate (MTA; Angelus, Londrina, Pr, Brazil) with different powder-to-water ratios.Three MTA groups were prepared using 4 : 1, 3 1 2 ratios. For radiopacity analysis, 10 × mm specimens arranged on occlusal films a cylinder dentine an aluminium stepwedge. The digitized radiographs evaluated Digora 1.51 software to determine radiographic density. time test was performed according...
To evaluate the volume of remaining filling material in mesial root canals mandibular molars after canal retreatment with different procedures performed sequentially.The 12 human first were instrumented using BioRace system until a size 25, .06 taper instrument. The roots filled gutta-percha and AH-Plus vertical compaction technique. specimens scanned microcomputed tomography voxel 16.8 μm before procedures. remove material, enlarged 40, .04 second step was to irrigate xylene attempt clean...

International Endodontic Journal , 45 162–168, 2012. Abstract Aim To evaluate the residual biovolume live bacterial cells, mean thickness and substratum coverage found in mixed biofilms treated with different irrigant solutions. Methodology Twenty‐five bovine specimens were infected intraorally...
Marciano MA, Ordinola‐Zapata R, Cunha TVRN, Duarte MAH, Cavenago BC, Garcia RB, Bramante CM, Bernardineli N, Moraes IG. Analysis of four gutta‐percha techniques used to fill mesial root canals mandibular molars. International Endodontic Journal . Abstract Aim To compare the percentage gutta‐percha, sealer and voids influence isthmuses in molars filled with different techniques. Methodology Canals 60 roots first were prepared ProTaper instruments size F2 (size 25, 0.08 taper) using a...
To evaluate the shaping ability of Reciproc and Twisted-File Adaptive systems in rapid prototyping replicas.Two mandibular molars showing S-shaped 62-degree curvatures mesial root were scanned by using a microcomputed tomography (μCT) system. The data exported stereolitograhic format 20 samples each molar printed at 16 µm resolution. canals 10 replicas specimen prepared with Transportation was measured overlapping radiographs taken before after preparation resin thickness instrumentation...
ABSTRACT This study analyzed the quality of obturation and physical properties MTA Fillapex AH Plus sealer. A sample 30 human maxillary central incisors were instrumented with Protaper until a F5 (50/05) file. Both sealers mixed Rhodamine‐B dye to allow visualization on confocal laser‐scanning microscope (CLSM). Next, canals filled using single cone technique. After setting, all samples sectioned at 2, 4, 6 mm from apex. CLSM was used analyze gaps sealer penetration into dentinal tubules....
ABSTRACT This study evaluated the shaping ability of HyFlex EDM and Rotate rotary systems in preparation S‐Shaped mesial root canals mandibular molars ( n = 13). After canal with instruments 0.25 0.40, specimens were for volume, volume increase, static voxels, accumulated hard tissue debris, centring transportation. 0.40 preparation, group exhibited a greater increase less hard‐tissue debris compared to p > 0.05). resulted increases across all thirds apical third < The displayed...
To analyse several physicochemical properties of AH Plus (Dentsply DeTrey, Konstanz, Germany), including setting time, flow, radiopacity and the degree conversion (DC); to correlate results with source material: from beginning, middle or end tubes in which they were supplied.Three experimental groups established for each property investigated. Group 1 corresponded material taken beginning A B; 2 tube; group 3 that tube. The flow studied according American National Standards...
Objective This study aimed to evaluate the influence of NiTi wire in Conventional (ProTaper Universal PTU) and Controlled Memory Gold PTG) instrument systems on quality root canal preparation. Material Methods Twelve mandibular molars with separate mesial canals were scanned using a high-definition microcomputed tomography system. The PTU PTG instruments used shape twelve each. after preparation F2 F3 systems. analyzed parameters included remaining dentin thickness at apical cervical levels,...
To assess the effect of 90°-oscillatory instrumentation with hand files on several morphological parameters (volume, surface area and uninstrumented surface) in C-shaped root canals after using a single-file reciprocation system (Reciproc; VDW, Munich, Germany) Self-Adjusting File System (SAF; ReDent Nova, Ra'anana, Israel).Twenty mandibular second molars C1 canal configurations were divided into two groups (n = 10) instrumented Reciproc SAF instruments. A size 30 NiTi K-file attached to...
The aim of this laboratory study was to compare the interfacial adaptation an epoxy-resin and a self-etch sealer in mesial root canals mandibular molars filled using System-B/Elements Obturation Unit. Sixty were prepared K3 rotary system up 35.04 instrument then with aid Unit either gutta-percha/ThermaSeal Plus (n=15) or Resilon/Real Seal SE (n=15). single cone technique both materials used as control. sealers stained Rhodamine B dye teeth sectioned at 2, 4 6 mm from apex. marginal evaluated...
The aim of this study was to quantify the residual filling material after removal, re-preparation with rotary or reciprocating files and passive ultrasonic irrigation (PUI). Twenty maxillary molars were prepared using ProTaper instruments up F1. teeth filled AH Plus gutta-percha points single-cone technique. Thereafter, specimens scanned a micro-computed tomography system (Micro-CT #1). Then, root canal removed Retreatment files, new scan performed #2). divided into two groups according...
