|Title:||Microleakage evaluation of intraorifice sealing materials in endodontically treated teeth|
|Abstract:||Objective. Evaluate intraorifice sealing materials Cavit, Vitremer, and Flow-it for the prevention of coronal microleakage in root-canal treatment. Study design. Root-canal treatment was performed on 80 extracted human molars. Three millimeters of coronal gutta-percha was removed from the coronal aspect of the root canal and replaced with one of the 3 filling materials. After thermocycling (5 degrees C to 55 degrees C and 5 days of immersion in dye, the teeth were cleared for stereomicroscope evaluation for evidence of dye penetration into the sealing material and along canal walls. Results. All groups showed dye penetration into the root canal. Cavit sealed significantly better than the other groups (P <.01), preventing the coronal leakage in 90% of the specimens. Flow-it exhibited the highest leakage (65% of specimens) and did not differ significantly from the Vitremer group, which showed dye penetration in 55% of specimens. Conclusion. Cavit sealed significantly better than Vitremer and Flow-it when used as intraorifice filling materials.|
