This study assessed the four to eight year outcome of apical surgery performed by graduate students in Phases I and II of the "Toronto Study". The study cohort included 155 teeth in 138 patients. Outcome was assessed by a blinded and calibrated examiner. Clinical and radiographic measures were used for a dichotomous outcome: "healed" (no signs and symptoms and Periapical Index score & le;2 or scar), or "diseased" (presence of signs and symptoms, or Periapical Index score & ge;3). The recall rate was 85% and the overall healed rate 74%. Bivariate analysis revealed a significantly higher healing rate for teeth with pre-operative lesion size 55 mm (86%) than>5 mm (65%), (chi2, P = 0.02). Logistic Regression revealed an increased risk of disease persistence for teeth with larger pre-operative lesions [OR = 3.81 (1.2--12.1 C.I.)], and pre-operative root-filling of adequate length [OR = 3.7 (1.2--11.8 C.I.)]. In conclusion, pre-operative lesion size and root-filling length may be significant predictors of outcome of apical surgery.
