title: Apical quality and adaptation of Resilon, EndoREZ, and Guttaflow root canal fillings in combination with a noncompaction technique.
abstract: The objective of this study was to compare the quality of Guttaflow (Coltene/Whaledent, Langenau, Germany), Resilon/Epiphany (Jeneric/Pentron, Kusterdingen, Germany), and EndoREZ (Ultradent Products, Inc, South Jordan, UT) root canal fillings. Thirty single-rooted teeth were randomly assigned to three groups: Resilon/Epiphany, EndoREZ, and Guttaflow. After radiography of the root canal fillings, the roots were sectioned horizontally at the level of 2 mm and 4 mm from the apex. The area of voids and adaptation to canal walls and points were evaluated using light microscopy and calculated through a computer program. The radiographs showed no significant differences between the materials (p > 0.05, Mann-Whitney U test). Evaluation of cross-sections revealed sealer adaptation >99% to the root canals and >98% to the points. Resilon/Epiphany had significantly higher values at 98.8% (standard deviation [SD] = 3.9%) than EndoREZ at 98.7% (SD = 1.1%), and Guttaflow at 98.5 (SD = 2.1%) (p < 0.05, Mann-Whitney U test). The absolute difference compared with Resilon/Epiphany was at 0.84% (0.44%-1.76%) for EndoREZ and at 1.08% for Guttaflow (0.00%-2.08%) (95% confidence interval, Hodges-Lehman). This outcome indicated an effective apical obturation using any of the three materials in combination with a noncompaction technique.
