About the Book

The 4-6 years outcome of initial endodontic treatment was assessed for Phase III (1998-1999) of the "Toronto Study". Of 532 teeth treated, 248 were from discontinuers (relocated or deceased). 142 from dropouts (non-responders or subjects who declined participation), 10 extracted, and 132 (50% recall) examined for outcome: "healed" (no apical periodontitis [AP], signs, symptoms) or "diseased". Phase III was analyzed then combined with Phases I and II (n = 373 teeth) for further analysis. The Phase III healed rate (86%) differed significantly for pre-operative AP. The combined Phase I to III healed rate (85%) differed significantly for pre-operative AP, gender, number of canals, and intra-operative complications, and logistic regression revealed an increased risk of persistent disease for pre-operative AP (OR = 3.6), multi-rooted teeth (OR = 2.2) and complications (OR = 2.2) and, among teeth with pre-operative AP, for step-back/lateral compaction technique (OR = 2.8) and complications (OR = 2.7).
