Abstract

The obturation with GuttaFlow Bioseal (GFB) in curved root canals is not clearly investigated due to the new generation of root filling material. This study compared the obturated surface area, extrusion of root filling material beyond the apical foramen and duration of obturation procedure in curved root canals using monocone obturation technique. Access cavity was prepared on twenty human mandibular molars. The root canal curvature of more than 10° determined according to Schneider’s method was included. Samples were prepared using Hyflex CM rotary files and divided into two groups (n=10). Group 1 [gutta-percha (GP) cone and GFB] and Group 2 [GP cone and RoekoSeal Automix root canal sealer]. The duration of obturation procedure was recorded and the obturation radiograph was taken. Samples were bisected and the mesial roots were sectioned horizontally to obtain 3 root segments; apical, middle and coronal. All resected roots were mounted on brass stubs, sputter-coated with thin platinum coating and observed under scanning electron microscope (SEM) at 70x magnification. The SEM images were transferred to the SketchAndCalc Area Calculator software. There were no statistically significant differences on the obturated surface area and extrusion of root filling material between Group 1 and 2 irrespective of the status of root canal curvature. The duration of obturation procedure in severe root canal curvature between Group 1 and 2 exhibited statistically significant difference. The obturated surface area and extrusion of root filling material were not affected by the status of root canal curvature. The duration of obturation procedure with GFB in severe root canal curvature was slightly longer. Neither root filling material was able to seal the curved root canal of mandibular molars completely. Both root filing materials in the present study can be opted depending on the clinical cases, material availability and clinician preference.
