ABSTRACT

Objetive: To conduct a preliminary study to compare the effectiveness in removing smear layer post instrumentation of NaOCl+ EDTA, NaOCl and Qmix activated with Endoactivator®, Irrisafe® and Endovac®. Methodology: 9 extracted single-rooted teeth were stored in thymol. They are divided into three groups, one for each irrigation solution and these in turn are divided into three subgroups, one for each activation system. The canals are instrumented with ProTaper ® system and irrigated with 1 ml of 5.25% NaOCl between files using syringes Monoject with 27 gauge needle. Then each group and subgroup are irrigated with the appropriate irrigation solution and activation system. Finally, the teeth are split longitudinally and samples are prepared to take pictures with MEB to assess the dentinal tubules cleanliness. Subsequently these data were subjected to statistical analysis. Results: It is appreciated smear removal layer in Qmix and NaOCl+EDTA groups, in NaOCl group, there were not smear layer elimination. The ultrasonic activation removed more smear layer than sonic one. We found no statistically significant differences between the sonic and Endovac activation. Conclusions: We have to do more samples, as this is only a pilot study to develop the technique, to draw relevant conclusions of the results obtained.
