Sargenti paste contains paraformaldehyde which can cause irreversible damage to tissues near the root canal system including the following: destruction of connective tissue and bone; intractable pain; paresthesia and dysesthesia of the mandibular and maxillary nerves; and chronic infections of the maxillary sinus.
