Abstract
Introduction: To compare the coronal sealing ability of SOR flowable Composite with other materials (f.iJ!E?K Z350 XT and GIC Fuji type II) and investigate the influence of different adhesive systems E?J19 V and Prime & Bond NT) on the sealing performance of SOR flowable Composite when used as an intra orifice barrier after root canal treatment.
Methods: 54 freshly extracted human mandibular first premolar teeth with single canal were selected for the experiment and root root canal treated. After completion of RCT the teeth were divided into two groups: experimental and control. The experimental group was further divided into four sub groups as XT group, SP group, SP group and GC group and the cont 394 words group was divided into two groups as PC group and NC group. The coronal 3.5 mm of gu. percha were removed from all the samples in the experimental group and and the prepared cavity is restored with the different restorative materials used in the experiment like f. iJ! E? - 9Q XT, SDR flow and GIC Fuji type II. The samples in the control group is simply left as it is with gutta percha till the coronal orifice. All the samples were then incubated for one yy h,Jh! TLQP.Y J. Q in hot and cold baths simultaneously for 500 cycles and finally stained in 1% Methylene blue solution for another one week in the incubator. The samples were then split longitudinally, and the depth of dye penetration was measured under a Stereomicroscope.
Results:
The rojs.; r: q.(P<0.05) l ft Sil.9 index of the SX group was significantly lower than the other groups while the coronal sealing ability of GC group was significantly lower than that of the other groups (P<0.05) and was not significantly different than the control group (P<0.05) CONCLUSION: GIC Fuji Type II can be considered unsuitable as an intra orifice barrier while SOR flowable composite in combination with J19 V can be used as an ideal intra orifice barrier after the completion of root canal treatment.
