This article is from Journal of Applied Oral Science, volume 22.AbstractObjective: To analyze possible correlations among tubular dentine cement penetration, adhesiveness and apical leakage in fillings performed with gutta percha and an endodontic cement based on epoxy amine resin. Material and Methods: Sixty similar, extracted human mandibular central incisors were irrigated, instrumented and filled following the same protocol. First, apical leakage was quantified by fluid filtration tests. Then, these same specimens were sectioned for analysis of tubular dentine cement penetration and the middle thirds were submitted to push-out tests to analyze the adhesiveness of the fillings. Results: In brief, the means and standard deviations with a confidence interval of 95% were as follows: tubular dentine cement penetration 8.875±4.540, adhesiveness 4.441±2.683 and apical leakage 0.318±0.215. The data were confronted using the Pearsons test P0.05, and it was possible to prove that there was no correlation between 1 tubular dentine cement penetration and apical leakage r2: 0.08276, 2 tubular dentine cement penetration and adhesiveness r2: -0.2412 and 3 adhesiveness and apical leakage r2: 0.1340. Conclusion: After analysis of these data, it could be observed that there exists no correlation among the variables analyzed in this study.
