To clarify the divergent viewpoints with respect to method of instrumentation in asymptomatic teeth with pulpal necrosis and associated periapical radiolucent lesions (PN/PL), this prospective study was undertaken. The subjects were 106 patients with quiescent cases of PN/PL. Alternately, 53 had periapical instrumentation and 53 had intracanal instrumentation. Prophylactic antibiotics were not administered but the patients were told to take an antibiotic at the first sign of swelling. Flare-ups, non-flare-up-associated swelling and pain, and cases in which there were no postoperative problems were evaluated at 1-day, at 1 week, and at 2 months. A 6.6% incidence of flare-up was found with no statistically significant difference between periapical instrumentation (7.5%) and intracanal instrumentation (5.7%). A 27.4% incidence of swelling was found with no statistically significant difference between periapical instrumentation (24.5%) and intracanal instrumentation (30.2%). A 43.4% incidence of pain was found, with no statistically significant difference between periapical instrumentation (15.1%) and intracanal instrumentation (47.2%). When moderate pain and severe pain were combined, the incidence was 21.7%, with no statistically significant difference between periapical instrumentation (15.1%) and intracanal instrumentation (28.3%). An incidence of patients having no postoperative problems of 41.5% was found, with no statistically significant difference between periapical instrumentation (47.2%) and intracanal instrumentation (35.8%). When flare-ups were combined with swelling, the incidence was 34.0%, with no statistically significant difference between periapical instrumentation (32.1%) and intracanal instrumentation (35.8%). When flare-ups were combined with pain, the incidence was 50.0%, with no statistically significant difference between periapical instrumentation (47.2%) and intracanal instrumentation (52.8%).(ABSTRACT TRUNCATED AT 250 WORDS)

D003790 Dental Pulp Necrosis Death of pulp tissue with or without bacterial invasion. When the necrosis is due to ischemia with superimposed bacterial infection, it is referred to as pulp gangrene.
