Three-Root Maxillary Bicuspid Obturation: Video

Jun 25, 2018

This video shows a 3-root maxillary bicuspid being obturated through a single chip camera attached to a Zeiss microscope.

Key Learning Points:

  1. Direct line access allows visibility of the obturation process to the point of the deepest pack level
  2. Gutta percha cones are placed with sealer circumferentially coating the apical third
  3. Only a microfilm of sealer is required to fill in the space between gutta percha cone and the dentin wall
  4. Excess sealer is gently expressed coronally during the multiple waves of compaction minimizing propulsion of sealer apically
  5. Multiple waves of heating and compaction are necessary to create apical deformation of the gutta percha into the apical terminus

Carrier Retreatment Detailed

Jan 28, 2018

Learn a specific technique for carrier obturator removal

Patient: 25 year-old male with asthma and seasonal allergies

Chief Complaint: Patient complained of “pressure around his back right tooth”

Dental History: Endodontic treatment had been performed with carrier obturation 2 years prior to the author’s examination. A core without a final full-coverage restoration had been placed.

Significant Findings (#30): Localized moderate gingival inflammation, draining buccal sinus tract, periapical radiolucencies (mesial and distal roots), radiolucent band along the furcation side of the mesial root, and one of the mesial root canals filled grossly short
