1. 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

2. Influence of remaining coronal thickness and height on biomechanical behavior of endodontically treated teeth: survival rates, load to fracture and finite element analysis
Abstract Objective To evaluate the effect of restorative strategy (fiber post vs cast post and core), coronal height (0 mm vs 2 mm) and thickness (higher than 1 mm vs lower than 1 mm) on survival rate, fracture resistance and stress distribution. Material and Methods Seventy-two bovine teeth were cleaned and allocated in six groups (n = 12). Twenty-four te

3. 3-D finite element analysis of the effects of post location and loading location on stress distribution in root canals of the mandibular 1st molar
Abstract Objective The purpose of this study was to evaluate, by using finite element analysis, the influence of post location and occlusal loading location on the stress distribution pattern inside the root canals of the mandibular 1st molar. Material and Methods Three different 3-D models of the mandibular 1st molar were established: no post (NP) – a

4. Assessing the risk zones of Chagas' disease in Chile, in a world marked by global climatic change
BACKGROUND Vector transmission of Trypanosoma cruzi appears to be interrupted in Chile; however, data show increasing incidence of Chagas' disease, raising concerns that there may be a reemerging problem. OBJECTIVE To estimate the actual risk in a changing world it is necessary to consider the historical vector distribution and correlate this distribution

5. Microscopic aspects of electrosensory system on the partially euryhaline lesser guitarfish
ABSTRACT The electrosensory system on elasmobranchs consists of subcutaneous electroreceptor organs known as ampullae of Lorenzini. The present study investigated the ampullae of Lorenzini morphology of the lesser guitarfish Zapteryx brevirostris, using light microscopy and scanning electron microscopy. The pore number found in the ventral skin surface is mu

6. Secretory spaces in species of the clade Dipterygeae (Leguminosae, Papilionoideae)
ABSTRACT Dipteryx, Pterodon and Taralea are legume genera known for secreting oils, produced in secretory canals and cavities, with medicinal properties. We analyzed the distribution, morphology and histochemistry of these glands in leaves and stems of Dipteryx alata, Pterodon pubescens and Taralea oppositifolia, three Neotropical species, using standard tec

7. Prevalence and morphometric analysis of three-rooted mandibular first molars in a Brazilian subpopulation
ABSTRACT The knowledge of the internal anatomy of three-rooted mandibular molars may help clinicians to diagnose and plan the root canal treatment in order to provide adequate therapy when this variation is present. Objectives: To determine the prevalence of three-rooted mandibular molars in a Brazilian population using cone beam computed tomography (CBCT)

8. Comparative study of three Marantodes pumilum varieties by microscopy, spectroscopy and chromatography
Abstract Marantodes pumilum (Blume) Kuntze (synonym: Labisia pumila (Blume) Fern.-Vill), Primulaceae, is well known for its traditional use as a post-partum medication among women in Malaysia. Three varieties of M. pumilum, var. alata Scheff., var. pumila and var. lanceolata (Scheff.) Mez. are commonly used. Nowadays, M. pumilum powder or extracts are commer

9. Prevalence of C-shaped root canal in a Brazilian subpopulation: a cone-beam computed tomography analysis
The aim of this study was to use cone-beam computed tomography (CBCT) images to evaluate the prevalence and configurations of C-shaped canals in permanent mandibular second molars among members of a Brazilian subpopulation. CBCT exams of 214 patients (406 teeth) were evaluated for: presence of C-shaped root canals, number of canals and direction of the root

10. Análise qualiquantitativa da permeabilidade dentinária do terço apical de diferentes grupos dentais / Qualiquantitative analysis of apical dentin permeability in different dental groups
This ex vivo study evaluated histochemically the dentin permeability of the root canal walls in the apical third of different human dental groups, analyzing the pattern of dentinal tubule distribution and the presence of sclerotic dentin in this region. Eighty teeth were used, being 8 of each dental group - maxillary and mandibular central incisors, lateral

11. Processes of decision of purchase of hygiene products staff between two canals: pharmacy and supermarket / Processos de decisão de compra de produtos de higiene pessoal entre dois canais: farmácia e supermercado
A concorrência transversal ou sobreposta entre os canais de varejo é uma realidade observada em todo o mercado de consumo brasileiro. Em um caso específico, farmácias e supermercados travam atualmente uma disputa pelo consumidor na venda de produtos de higiene pessoal. Essa disputa deveria ser ganha pelos supermercados que, com suas economias de escopo e

12. Cortical bone porosity visualization using mercury porosimetry intrusion data
Cortical bone porosity of bovine tibia samples has been investigated using the mercury intrusion porosimetry (MIP) technique. Cortical bone porosity range from 10 nm (caniculae) to 40 mm (Harvers canals), well in the measuring range region for the MIP technique. Samples from fresh bovine cortical bone were treated, dried and cut into ~ (3x1x1) cm pieces .The
