fa Wettability of root canal sealers on intraradicular dentine treated with different irrigating solutions اندودانتیکس Endodontics پژوهشي Research <p> <strong>Objectives </strong></p><p> The aim of this in vitro study was to evaluate the wettability of AH Plus and ThermaSeal Plus sealers on intraradicular dentine treated with different irrigating solutions.</p><p> <strong> Methods</strong> </p><p> Fifty anterior teeth were decoronated and split longitudinally. Each root half was divided into 5 groups (n=10). Group I: 5mL of 2.5% NaOCl+QMix. Group II: 5mL of 2.5% NaOCl+17% EDTA. Group III: 5mL of 2.5% NaOCl+7% maleic acid. Group IV: 5mL of 2.5% NaOCl. Group V: 5mL of distilled water. Irrigation regimens were performed for 1min. Each specimen was placed inside a Dynamic Contact Angle Analyser. A controlled-volume droplet of sealer was placed on each specimen and the static contact angle was analysed. </p><p> <strong>Results</strong></p><p>  The contact angle made by both sealers with EDTA-irrigated dentine was significantly larger when compared to the other irrigants (P<0.05). For ThermaSeal Plus, contact angles produced on maleic acid-, NaOCl- and distilled water-irrigated dentine were not significantly different, but were all significantly larger than the contact angle produced on QMix-irrigated dentine (P<0.05). For AH Plus, contact angles produced on NaOCl- and distilled water-irrigated dentine were not significantly different, but were significantly larger than those made by maleic acid and QMix. </p><p> <strong>Conclusion</strong></p><p> <strong> </strong>When used as a final irrigant, QMix favours the wetting of root canal dentine by both AH Plus and ThermaSeal Plus sealers. Maleic acid shows a promising result when compared to EDTA and NaOCl. Wettability of both sealers is the worst on EDTA-irrigated dentine. <strong></strong></p><p> <strong>Clinical significance</strong> </p><p> The present study highlights the effect of newer endodontic irrigating solutions on the wettability of sealers on to the root canal dentine, which is required for obtaining good obturation seal. </p><hr><p></p><p> <strong>Source: </strong>Journal of Dentistry</p><p> <a href="http://www.jodjournal.com/article/S0300-5712(13)00096-1/abstract" target="_blank"><font color="#0000ff">Full Text</font></a></p> Contact angle, EDTA, NaOCl, QMix, Maleic acid, Wettability 0 0 http://idai.ir/browse.php?a_code=A-10-32-2165&slc_lang=fa&sid=1 Nidambur Vasudev Ballal 100319475328460010172 100319475328460010172 No Department of Conservative Dentistry & Endodontics, Manipal College of Dental Sciences, Manipal, Manipal University, Karnataka, India Adlyn Tweeny 100319475328460010173 100319475328460010173 No Department of Conservative Dentistry & Endodontics, Manipal College of Dental Sciences, Manipal, Manipal University, Karnataka, India Khaled Khechen 100319475328460010174 100319475328460010174 No Dentsply Tulsa Dental Specialties, Tulsa, OK, USA K.
