2. Root canal preparation using micro-computed tomography analysis: a literature review
Abstract: This literature review has critically analyzed the published research related to the biomechanical preparation of root canals with three-dimensional analysis using micro-computed tomography (micro-CT). In December 2017, six databases (PubMed, Cochrane, Web of Science, Embase, Scopus, and Science Direct) were accessed using keywords to find articles

3. Push-out bond strength of different tricalcium silicate-based filling materials to root dentin
Abstract: The aim of this study was to evaluate the bond strength of different triccalcium silicate cements to retrograde cavity using a push out test. Thirty maxillary central incisors were shaped using #80 hand files and sectioned transversally. Root slices were obtained from the apical 4 mm after eliminating the apical extremity. The specimens were embedd

4. 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

5. 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

6. Does index tumor predominant location influence prognostic factors in radical prostatectomies?
ABSTRACT Purpose To find any influence on prognostic factors of index tumor according to predominant location. Materials and Methods Prostate surgical specimens from 499 patients submitted to radical retropubic prostatectomy were step-sectioned. Each transverse section was subdivided into 2 anterolateral and 2 posterolateral quadrants. Tumor extent was e

7. Comparação do comprimento de trabalho do canal radicular usando tomografia computadorizada de feixe cônico, radiografia periapical e localizador apical eletrônico / In vivo comparison of root canal working length using cone beam computed tomography, periapical radiograph, and electronic apex locator
Introdução: Estratégias para obtenção do comprimento de trabalho para preparar e obturar canais radiculares têm sido tema relevante de discussão em Endodontia. O objetivo deste estudo foi comparar in vivo as medidas de comprimento de trabalho do canal radicular determinadas por meio da tomografia computadorizada de feixe cônico (TCFC) com as obtidas

9. Influência do alargamento foraminal na anatomia apical e na qualidade de selamento após obturação / Influence of apical foramen widening on apical foramen morphology and apical sealing
Introduction: The aim of this study was to evaluate the influence of the working length and apical foramen widening on the anatomy of the apical foramen and on the sealing ability after root canal filling. Methods: Fifty-five palatal roots of maxillary molars were selected. The samples were randomly divided into three groups (n=15) according to the different

10. Radiographic image analysis of apicetomized roots irradiated with Nd:YAG laser using imaging processing of direct digital radiographs / Análise da imagem radiográfica de raízes apicetomizadas e irradiadas com laser de Nd:YAG por meio do processamento de imagem de radiografias digitais diretas
In this research, we carried out an evaluation of the digital radiographic image of dental root-ends irradiated with Neodymium Yttrium Aluminum Garnet (Nd:YAG) laser after apical resection. With the intention of founding alterations in the digital radiographic image of the roots caused by laser irradiation, we developed an in vitro experimental model. We mad

11. Avaliação ex vivo da precisão do localizador eletrônico Root ZX II na determinação da posição do limite CDC, utilizando-se o registro 1 do visor
It is generally accepted that root canal treatment procedures should be confined within the root canal system. To achieve this objective the canal terminus must be detected accurately during canal preparation and precise control of working length during the process must be maintained. Several techniques have been used for determining the apical canal terminu

"Terapia endodôntica associada à irradiação do canal radicular com laser de diodo: avaliação térmica, morfológica, microbiológica e da infiltração marginal apical" / Endodontic root canal therapy usindg diode laser irradiation: thermographic, morphological, microbiological and marginal apical leakge studies
The aim of this study was to evaluate the effects of diode laser irradiation associated with endodontic therapy. The aspects analyzed were: temperature rise at the external root surface, morphological changes at the dentine root walls, apical marginal leakage after root sealing, and microbiological reduction after laser irradiation. The temperature rise in i
