Borges RP, Sousa‐Neto MD, Versiani MA, Rached‐Júnior FA, De‐Deus G, Miranda CES, Pécora JD. Changes in the surface of four calcium silicate‐containing endodontic materials and an epoxy resin‐based sealer after a solubility test. International Endodontic Journal , 45 419–428, 2012. Abstract Aim To compare changes structure elemental distribution, as well percentage ion release, with well‐established sealer, submitted to Methodology Solubility AH Plus, iRoot SP, MTA Fillapex, Sealapex...
Abstract Aim To evaluate setting time, solubility and disintegration, flow, film thickness, dimensional change following in a dual‐cured resin root canal sealer Epiphany TM compared with an epoxy‐resin‐based AH Plus . Methodology The experiments were performed according to ANSI/ADA Specification 57 which tests the physicochemical properties of endodontic sealing materials. Five samples each material tested for properties. In addition, deionized distilled water from test was submitted...
To assess the physicochemical properties and surface morphology of AH Plus, Epiphany, Epiphany SE root canal sealers.Five samples each material were employed for test according to ANSI/ADA specification 57. The assigned four groups: (i) Plus; (ii) Epiphany; (iii) + Thinning Resin; (iv) SE. distilled water used during solubility was submitted spectrometry verify release calcium ions. morphologies external cross-section analysed by means a scanning electron microscope (SEM). Statistical...
To investigate the anatomy of single-rooted mandibular canine teeth using microcomputed tomography (μCT).One hundred straight human canines were selected from a pool extracted and evaluated μCT. The each tooth (length roots, presence accessory canals apical deltas, position major diameter foramen distance between anatomical landmarks) as well two- three-dimensional morphological aspects canal (area, perimeter, form factor, roundness, minor diameter, volume, surface area structure model...
To evaluate the efficacy of four final irrigation protocols on reduction hard-tissue debris accumulated within mesial root canal system mandibular first molars using micro-CT analysis.Forty roots with a single and continuous isthmus connecting mesiobuccal mesiolingual canals (Vertucci's Type I configuration) were selected scanned at resolution 8.6 μm. Canals enlarged sequentially WaveOne Small Primary instruments activated in reciprocating motion without intracanal to allow accumulate...
Fornari VJ, Silva‐Sousa YTC, Vanni JR, Pécora JD, Versiani MA, Sousa‐Neto MD. Histological evaluation of the effectiveness increased apical enlargement for cleaning third curved canals. International Endodontic Journal , 43 988–994, 2010. Abstract Objective To evaluate influence size on canals prepared with rotary instruments. Methodology Forty‐four mesiobuccal maxillary molars teeth were instrumented to different sizes (30, 0.02; 35, 40, 45, 0.02) using a crown‐down technique. After canal...
To compare the accuracy of clearing technique and cone beam computed tomography (CBCT) in assessment root canal configurations using micro-computed (micro-CT) imaging system as reference standard.Thirty-two mesial roots mandibular first molars, selected on basis micro-CT scans (voxel size: 19.6 μm) presenting several configurations, were evaluated 2 CBCT scanners (voxels sizes: 120 μm 150 followed by technique. Two examiners analysed data from each method classified anatomical configuration...
To assess the percentage volumes of filling materials and voids in oval-shaped canals filled with either cold lateral compaction or warm techniques, using micro-computed tomography (micro-CT).Twenty-four single-rooted maxillary premolar teeth were selected root prepared assigned to two groups (n = 12), according technique: (CLC) vertical (WVC). Each specimen was scanned a micro-CT device at an isotropic resolution 12.5 μm. Percentage calculated, data statistically analysed Student's t-test...

Aim To assess the and surface morphology AH Plus, GuttaFlow, RoekoSeal Activ GP Methodology Five samples each material were evaluated for setting time, dimensional alteration, solubility radiopacity tests, according to ANSI/ADA Specification 57. A total 50 mL deionized distilled water from tests...
To compare the shaping ability of four root canal instrumentation systems in oval-shaped canals using micro-computed tomographic analysis.Forty anatomically matched mandibular incisors were scanned and assigned to groups (n = 10), according preparation protocol: BioRace, Reciproc, Self-Adjusting File (SAF) TRUShape systems. After instrumentation, specimens rescanned, registered pre- postoperative datasets examined evaluate percentages accumulated hard-tissue debris, untouched walls dentine...
The aim of this study was to compare the percentage non-instrumented area root canals prepared with different enlargements using single-file reciprocating systems (Reciproc and WaveOne) a conventional multi-file rotary (BioRaCe) system by micro-computed tomographic analysis. Thirty mesial roots mandibular molars moderate curvature (10° 20°) presenting type II Vertucci canal configuration similar internal volume were chosen scanned at an isotropic resolution 14.16 µm. sample assigned 3 groups...
