Pulp and periapical diseases are initiated primarily by microbial factors. Healing, therefore, occurs when the infection is properly controlled and the host-parasite relationship is made favorable for the host. This lecture will outline the etiology and clinical features of refractory endodontic disease. Extra-radicular endodontic infections (microbial and virus), 'sulfa-granules' and periapical biofilm will also be reviewed.
