Abstract
  • The purpose of this retrospective study was to evaluate the radiographic and clinical outcome of teeth with chronic apical periodontitis receiving primary root canal therapy when obturated with gutta-percha and Roth's Eugenol Sealer compared to Resilon and Epiphany Sealer. Radiographic outcome was evaluated using the Periapical Index, while clinical outcome was evaluated with objective and subjective tests on 141 teeth. Univariate analysis found the presence of a permanent restoration, pre-operative PAI score, tooth type and age to be significant in predicting radiographic outcome. Univariate and multivariate analysis found age and presence of a permanent restoration as significant predictors of clinical outcome (p<0.05). Placement of full coverage restorations was found to significantly impact survival (p=0.003), especially in teeth with at least one compromised marginal ridge (p=0.002). Teeth filled with gutta-percha or Resilon had statistically indistinguishable differences in radiographic and clinical outcome, and are comparable to outcomes presented in the endodontic literature.
