Comparative evaluation of postobturation apical seal following intracanal irrigation with maleic acid or a combination of chlorhexidine and ethylenediaminetetraacetic acid: An in vitro study

摘要: Aim: The aim of this study is to evaluate postobturation apical seal following intracanal irrigation with maleic acid (MA) or a combination chlorhexidine (CHX) and ethylenediaminetetraacetic (EDTA). Materials Methods: Thirty single-rooted human premolar teeth were decoronated subjected root canal instrumentation. Based on the final irrigating regimen, samples divided into 3 groups: Group 1- Irritrol (EDTA + CHX), 2–7% MA, 3–0.9% Saline (control). then obturated placed in humidor for 7 days. Specimens microleakage analysis at 24 h, days, 14 days using glucose filtration technique. analyzed kit calorimeter 500 nm wavelength. Data one-way ANOVA, post hoc Tukey's test, Games–Howell Bonferroni test. Results: There overall significant differences mean scores among all three groups (P Conclusion: Final improved when compared 7% MA.
