The potential for more trade by rail between Brazil and its neighbours in the Southern Cone

This edition of the FAL bulletin contains the summary of a review carried out by ECLAC concerning the potential for a higher level of trade via rail between Brazil and other countries of the expanded Mercosur, and through those countries with Asia.At present, such trade occurs at very low levels, except in the case of trade with Bolivia. Some projects are planned, however, that would improve integration of the railway network in the Southern Cone, without requiring very significant levels of investment. If those projects are executed, the prospects would be good in the medium and long term for substantially increasing trade by rail in the region.

The fifth freedom and the Southern Cone: a new perspective

An ECLAC document to be published in the near future examines a subject that has become a frequent topic of discussion in recent years, particularly in the Southern Cone of Latin America (Argentina, Bolivia, Brazil, Chile, Paraguay, Peru and Uruguay), where the greatest volume of land transport in South America is concentrated. Against a background of economic liberalization and integration in the region, and at a time when the development of regional transport infrastructures is growing in importance, the ECLAC Transport Unit analyses the Southern Cone Agreement on International Land Transport (Valparaíso, 1989) in an effort to give it fresh relevance and to determine whether its provisions can cope with the new challenges thrown up by more open international transport markets and management.

Comparison of the effects of TripleGates and Gates-Glidden burs on cervical dentin thickness and root canal area by using cone beam computed tomography

The search for new instruments to promote an appropriate cervical preparation has led to the development of new rotary instruments such as TripleGates. However, to the best of the authors' knowledge, there is no study evaluating TripleGates effect on the “risk zone” of mandibular molars. Objectives: The aim of this study was to evaluate the effects of a crown-down sequence of Gates-Glidden and TripleGates burs on the remaining cervical dentin thickness and the total amount of dentin removed from the root canals during the instrumentation by using cone beam computed tomography. The number of separated instruments was also evaluated. Material and Methods: Mesial roots of 40 mandibular first molars were divided into 2 equal groups: crown-down sequence of Gates-Glidden (#3, #2, #1) and TripleGates burs. Cervical dentin thickness and canal area were measured before and after instrumentation by using cone beam computed tomography and image analysis software. Student’s t-test was used to determine significant differences at p<0.05. Results: No significant differences (p>0.05) were observed between the instruments, regarding the root canal area and dentin wall thickness. Conclusion: Both tested instruments used for cervical preparation were safe to be used in the mesial root canal of mandibular molars.
