| 17. 1-2mm of the gutta-percha is removed by a heat carrier. |
| 18. A plugger without binding the canal wall is again used to compact the next layer of warm gutta-percha. |
| 19. The heat carrier is again used to remove more gutta-percha 1-2mm alternating between transferring carrier and the plugger. |
| 20. As the canal narrows, a smaller plugger is selected to compact in a more apical direction, i.e. #11-10-9-8. (Obtura Condenser use 4,3,2,1) |
| 21. Each plugger is measured in the canal to access the level at which the gutta-percha is being removed and compacted. Refer to your note on the measurement make previously and stay short of these depths. A radiograph should be taken to evaluate the progress in compaction. |
| 22. Vertical compaction progresses by alternating heat and compacting (packing rhythm) until the smallest size is reached to a depth of at least 5-7mm from the apical opening. A radiograph may be taken at this point to confirm the apical packing. |
| 23. The back packing will be performed without any sealer, if a post and core restoration is not planned. |
| 24. Trim off 3mm of fine-medium gutta-percha and place it into the canal touching the base of the gutta-percha or Obtura II gun. |
| 25. Use the heat carrier to shear off the gutta-percha about 2-3mm below the orifice. |
| 26. Compact the warm gutta-percha down to the base with the smallest plugger. |
| 27. As second piece is added in the same manner by repeating warming with the heat carrier and compacting with the smallest plugger. |
| 28. Continue backpacking until the gutta-percha reaches to the level 2mm from the gingival margin. |
| 29. Take a radiograph to evaluate the homogeneity of the backpacking. |
| 30. Place cotton pellet Cavit into the access opening. |
| 31. Remove rubber dam and take a post-operative radiograph. |
