ABSTRACT

Objetivo: evitar la microfiltración en el conducto radicular y remanente de obturación usando cianocrilato para sellar la cavidad. Material y método: investigación de tipo experimental, transversal, comparativo, realizada en 60 caninos inferiores humanos, extraídos íntegros, un conducto sin calcificación interna. Se les seccionó la coronaria, estandarizando la porción radicular en 16 mm y la preparación biomecánica a 15 mm, aplicando la técnica ápico coronal. Fueron clasificados en tres grupos: I: desobturados, sin compactación apical ni impermeabilización, II: desobturados, con compactación apical, sin impermeabilización, III: desobturados, con compactación apical, impermeabilizados con cianocrilato. El conducto y remanente de obturación fueron barnizadas con cianocrilato, usando conos de papel Nº 55. La superficie externa fue cubierta con dos capas de esmalte de uñas, excepto el tercio apical y superficie cervical. Secados por tres horas, fueron sumergidas en azul de metileno por 48 horas en frascos rotulados Pasadas 3 horas se lavaron con agua y se secaron por 24 horas. Se retiró el barniz, luego congelados 24 horas. Finalmente, se realizaron muescas por proximal para fracturarlas. Resultados: el Grupo III presentó una menor microfiltración en comparación con los otros grupos. En el tercio apical propiamente dicho se encontró una menor filtración en comparación con los otros tercios estudiados. Estos fueron analizados usando la prueba de Kruskall Wallis, que determina que existe diferencia entre los niveles de microfiltración en los distintos grupos y tercios de las piezas dentarias estudiadas. Conclusión: el cianocrilato es un material impermeabilizante y puede ser usado en el conducto radicular.


Objective: to avoid the microfiltration in the root canal using cianocrylate to seal the cavity. Material and Method: experimental, transversal, comparative, done in 60 extracted bottom human canines, one single canal, no calcification, standardizing the radicular portion to 16mm, the biomechanical preparation to 15mm. Three groups were classified: I: desobturated, without apical compaction or coating, II: desobturated, with apical compaction and without coating. III: desobturated, with apical compaction and coated with cyanocrylate using paper cones Number. 55. The external side was covered with two coats of nail polish, except for the apical third and the cervical surface. Dried for three hors, were submerged in blue methyl for 48 hours. After three hours, they were washed up with water and dried for 24 hours. The varnish was taken out and were frozen for 24 hours. Finally they were broken to observe, measure and analyze the micro filtration. Results: the Group III presented a less microleakage compared with other groups as well as in the third apical itself was a minor leak in comparison with the other thirds. These were analyzed using the Kruskal Wallis test, which determines that there is difference between the levels of microfiltration in the different groups and thirds of the teeth studied. Conclusion: the cianocrilate is a impermeable material and can be used in the root canal.

ABSTRACT

By means of Kato-Katz technique 113,254 coprological samples of the human population belonging to 100 counties from Venezuela were analyzed. It was determined the following prevalences: ascaris lumbricoides 26,8 percent, trichuris trichiura 32,7 percent and hookworm 5,6 percent. It was found a strong correlation between a. lumbricoides and t. trichiura infection (p<0,001), a significant correlation between t. trichiura and hookworn (p<0,5) and no correlation between a. lumbricoides and hookworm
