Hello Dr. Nasseh
Thank you for these CBLs. I feel confident wanting to do root canals after watching these. I have a question regarding the obturation. I was taught to use the System B to remove the coronal gutta percha to leave around 5 mm of apical gutta percha and then backfill with the Calamus or Obtura. When and why was this indicated?
