A periapical radiolucency associated with tooth No. 21, which had inadequate root canal therapy with an adequately sealing crown 3 years previously.

Figure 1

A #15 scalpel is used to incise 360° in the sulcus and perform a supra-crestal fiberotomy.

Figure 2

Minimum elevator use is employed to loosen the tooth.

Figure 3

The root surface was examined carefully for cracks and determined to be completely intact.

Figure 4

A 3-mm apicoectomy was performed using a 1557 SaberCut Bur.

Figure 5

Retropreparation was performed using a #2 surgical-length slow-speed bur to a depth of 3 mm, connecting the isthmus in this oval canal.

Figure 6

Retropreparation was performed using a #2 surgical-length slow-speed bur to a depth of 3 mm, connecting the isthmus in this oval canal.

Figure 7

Retropreparation was performed using a #2 surgical-length slow-speed bur to a depth of 3 mm, connecting the isthmus in this oval canal.

Figure 8

EndoSequence RRM was injected to the depth of the retropreparation and filled to the cavosurface margin. A layer of EndoSequence RRM Putty was then placed on top of the RRM, and the excess was removed with a micro-brush.

EndoSequence RRM was injected to the depth of the retropreparation and filled to the cavosurface margin. A layer of EndoSequence RRM Putty was then placed on top of the RRM, and the excess was removed with a micro-brush.

After suctioning the clot in the socket, the tooth was repositioned back in the socket and some pressure was applied.

Figure 12

Immediate postoperative radiograph shows a dense retrofilling deep into the canal.

Figure 13

The 6-month recall radiograph shows complete healing of the apex.

Figure 14

The 6-month recall photograph also shows clear clinical appearance without any mobility.

Figure 15

The 6-year recall radiograph shows that the tooth is still functioning and lacking any pathology.
