This video shows a 3-root maxillary bicuspid being obturated through a single chip camera attached to a Zeiss microscope.
Key Learning Points:
- Direct line access allows visibility of the obturation process to the point of the deepest pack level
- Gutta percha cones are placed with sealer circumferentially coating the apical third
- Only a microfilm of sealer is required to fill in the space between gutta percha cone and the dentin wall
- Excess sealer is gently expressed coronally during the multiple waves of compaction minimizing propulsion of sealer apically
- Multiple waves of heating and compaction are necessary to create apical deformation of the gutta percha into the apical terminus
