Further research to identify suitable filling materials and obturating systems to completely fill the resorbed area is essential (20).
Clinical efficacy of various root canal obturating methods in primary teeth: a comparative study.
For further refining and increasing the length of the obturating part, tray adhesive was applied on the extension of this part.
The quality of root canal filling was scored on the following modified three-point scale: (1) a good score for homogenous filling obturating the entire prepared root canal, well adapted to the canal wall, with only a few minor areas of relative radiolucency (diameter: [less than or equal to] 0.25 mm; without porosity); (2) a satisfactory score for imperfect filling with irregularities of [less than or equal to] 1 mm, where the filling may be slightly shorter (diameter: [less than or equal to] 0.5 mm) than the working length (few porosities); and, (3) a bad score for inadequately filled canals with irregularities (diameter: > 1 mm), where the filling diameter may be > 0.5 mm shorter than the working length (several porosities).
They compared the gutta-percha lateral compaction technique and obturating the entire canal length with MTA alone and concluded that gutta-percha provides better seal compared to MTA; however, the present study showed better seal with MTA.
The air may relocate right after a trauma or within two weeks, which is connected with a formation of scarce obturating the sinuses [8].
RealSeal 1, according to the manufacturer, bonds to both the obturating material and the root canal walls to provide a better seal of the root canal by creating a "monoblock".
According to Greg Palkowitsh, who engineered the bullet, the FPB has an obturating cup, otherwise known as a hollow base.
It uses a better grade of steel (to obtain thinner walls) and a more powerful explosive so as to provide the optimum fragmentation from the smaller payload, is well-shaped and provided with an efficient obturating ring which ensures that the propelling gas stays behind the bomb and gives it velocity instead of leaking past into the barrel.
[4] As the gutta-percha is solid core obturating material, voids are more commonly seen in the sealer mass or at the interface with the sealer which allows the passage of toxin to pass into the periapex and decreases the quality of obturation.
In-vitro studies with scanning electron microscopy of replicas of resected root ends have shown that commonly used burs for root-end resection may produce disruption of the obturating material (9,10).
