Apical microfiltration in ducted tubes with and without dentinary pretreatment: In vitro Study
The apical microfiltration is one of the causes of the failure in the endodontic treatments, which is due to the poor adaptation of the materials, to the solubility of the cement sealer, or to the contraction of the root filling. Objective: To determine apical microfiltration in sealed ducts withou...

| Sumario: | The apical microfiltration is one of the causes of the failure in the endodontic treatments, which is due to the poor adaptation of the materials, to the solubility of the cement sealer, or to the contraction of the root filling. Objective: To determine apical microfiltration in sealed ducts without and with EDTA and citric acid pretreatment. Materials and methods: 30 recently extracted uniradicular premolar teeth were instrumented and randomly divided into 3 groups of 10 pieces each, being: G1= teeth without dentin pretreatment (control group), G2= teeth with 17% EDTA dentin pretreatment, G3= teeth with 10% citric acid pretreatment. All the groups were then irrigated with 5.25% NaOCl, followed by physiological saline and finally sealed with TopSeal resinous cement (Dentsply De Trey, Konstanz, Germany). After diaphanization of the teeth, observation was made in an optical stereomicroscope and the linear microfiltration was measured with a digital calibrator. The data were processed and analyzed through the ANOVA test and the Tukey test with a level of significance of 5%. Results: The means were 1.61, 0.54, 0.12 for G1, G2 and G3 respectively. There was a significant difference between the groups that received pretreatment dentin with the control group (p <0.001). No significant differences were found between the groups that received dentin pretreatment (p<0.364). Conclusion: The two types of dentin pretreatment efficiently decreased apical microfiltration without a statistically significant difference between the two. |
