It is most commonly used during endodontic (root canal) surgery, such as an apicoectomy. Its plain purpose is to seal the root canal from the root tip side when a standard root canal approach is not enough. It helps reduce leakage of bacteria and fluids between the root canal system and surrounding tissues."}
