Evaluation the Sealing Ability of Different Types of Sealers and Obturation Techniques
This study was conduct to assess the sealing ability of Gutta flow2 in comparison with Adseal & Endofill sealers by using different obturation techniques. Thirty extracted premolarswere utilized as a part of this investigation, the roots were prepared by wave one (large file) as master file, samples randomization was categorized into three categories harmonious root filling materials, group(I) lateral compaction with Endofill sealer, group(II) single cone obturation with Adseal sealer, group(III) Gutta Flow2 with master cone. After incubation period for three days, all samples covered with two layers of nail coating aside from two mm at the zenith. Samples immersion was done in staining solution for 2 days, then the roots sectioned longitudinal and the depth of the color pathway from above was analyzed utilizing a stereomicroscope. The Gutta Flow2 group has lowest mean values(0.6660)mmof apical dye penetration in comparison with other groups, and the lateral compaction with Endofill sealer has highest mean values (0.7490)mm of apical dye penetration.
