Effect of different irrigation regimens on the wettability of Sealer Plus BC and AH Plus sealers on intraradicular dentin: An in vitro study

Abstract

Introduction: Irrigants play a major role in eliminating bacteria and modify the wettability of radicular dentin, thus impacting its interaction with restorative materials. Hence, the aim of the current research was to evaluate and compare the effect of 17% ethylenediaminetetraacetic acid (EDTA) and 7% maleic acid (MA) on the wettability of Sealer Plus BC and AH Plus sealers. Materials and Methods: Thirty single-rooted premolars were decoronated and longitudinally sectioned to form 60 samples. The samples were then arbitrarily separated into three groups (n = 20) determined by the irrigation protocol: Group I (2.5% sodium hypochlorite [NaOCl] + 17% EDTA), Group II (2.5% NaOCl + 7% MA), and Group III (2.5% NaOCl + distilled water). Each group was then split into two subgroups (n = 10) based on the sealer utilized: Subgroup A (Sealer Plus BC sealer) and Subgroup B (AH Plus sealer). The sealers were mixed and placed on the samples. Contact angles of the sealers were determined with a goniometer. The intragroup and intergroup comparison was conducted by Two way-ANOVA test with a significance level of P < 0.01. Results: The wettability of both sealers was favorably influenced by the final irrigant rinse with 7% MA and 17% EDTA, although there was no statistical difference between both sealers in the MA group (P > 0.01). AH Plus demonstrated a better wettability than Sealer Plus BC in the EDTA group (P < 0.001). Both Sealer Plus BC and AH Plus sealers demonstrated lower contact angles on final irrigation with 7% MA in comparison to 17% EDTA. Conclusion: As a final irrigant, 7% MA increased the wettability of both Sealer Plus BC and AH Plus sealers compared to 17% EDTA.
