Abstract

Abstract
Aim of the study: this study was designed to compare penetration ability of two different obturation techniques into simulated lateral canals. Materials and methods: sixty-eight non carious freshly extracted teeth were decoronated, instrumented up to size 30/.04,Irrigated with 17% EDTA and 5% NaOCl. Simulated lateral canals were Created in each third, at 3, 6, 11 mm short of working length, while diaphonization of the specimens, with size 10 ISO k-files. Samples were divided into two equal groups (n=34) In accordance with obturation methods, Guttacore and Continuous wave of condensation and examined under stereomicroscope after obturation. Mann Whitney and Kruskal Wallis tests were used to statistically analyze the data. Results: For Guttacore group, showed significantly higher median score for filling penetration ability than continuous wave group at apical third (p>.043), while continuous wave penetration ability was significantly higher at the apical third (p>.048). There was no significant difference in filling penetration among the three thirds for continuous wave (p>.679). for Guttacore technique apical third showed significantly higher filling penetration ability than both coronal and middle thirds (p>.001). Conclusion: both Guttacore carriers and continuous wave techniques exhibited proper penetration into simulated lateral canals. While Guttacore carriers provided better filling ability in the apical area, The Continuous wave vertical condensation had superior filling ability in the middle third of the root canal.
