Obturation

  1. Debride, clean and shape the root canal system.
  2. Rinse the canals with a NaOCl solution (3.0 to 6.0%).
  3. Dry the canal well with paper points.
  4. For use with gutta percha, apply a light coating of MTA Plus (mixed with the gel to a syrupy, stringy consistency) to the canal walls. Coat the obturation points with the mixed MTA Plus material and insert in the canal.
  5. For complete obturation, make a thin mixture of powder and gel and apply to paper points. Use the paper points to place the material at the apex. Use a thicker mixture to gently compact MTA Plus material into the remainder of the canals.
  • DO NOT OVERFILL the root canals!
  • AVOID AIR BUBBLES in the material.
  • DO NOT PUMP the gutta percha point in the canal.
  • MINIMIZE OVEREXTENSION of the material beyond the apex.
  • Confirm placement of the material in the complete root canal system with a radiograph.

NOTE:  For removal in retreatment, use standard mechanical techniques. If only MTA Plus material is used for obturation, use ultrasonic instruments. Acetic acid can be used to assist with dissolution of MTA Plus.
