Introduction: Root remediation when the initial treatment fails is the most basic treatment before any other surgical procedure. The aim of this study was to evaluate the factors affecting the success and failure of endodontic treatment in a period of 6-24 months.Materials and Methods:This cross-sectional analytical study was performed during 1996-94 with the participation of 76 patients, 19 (25%) male and 57 (75%) female who were referred for non-surgical re-treatment of endodontics after failure of initial treatment. Took. The re-treatment method was conventional. Radiographic and clinical signs were compared before and after re-treatment. These changes were categorized according to Heald, Healing & (success) and non-healed (Failure). The ability to chew was also recorded after the follow-up period. Wilcoxon signed test, rank regression test (Ordinal regression analysis), Mc Nemar test were used for statistical analysis.
Results: The improvement of clinical symptoms was 98.7% (P = 0.0001). And (88.2%) patients had full ability to chew after re-treatment of the root. Following rank regression test, canine teeth had a higher chance of recovery than other types of teeth (P <0.000). With age, the chance of recovery decreased (P = 0.033). The left teeth were more likely to recover (P = 0.008). Goodness of Fit, measured by Pearson chi-square test, confirmed the findings (χ2 = 87.667, P = 0.942). McNemar analysis confirmed the positive effect of therapeutic intervention on patients’ success (success) (p <0.001).
Conclusion:Following re-treatment and follow-up of dental treatment in this study, re-treatment is still the first non-invasive step in achieving success in achieving tooth
preservation.
