The purpose of the present research was to assess the efficacy of endodontic re-treatment of root canal filing and associated periapical changes based on radiographic interpretation.
Methodology
In our study around two hundred radiographs of endodontic treatment which has failed, were evaluated. In these cases, the periapical status was assessed with the help of scoring system known as periapical index (PAI). More than 3 PAI reveals presence of periapical lesion.
Results
A statistically noteworthy rise in score 1 as well as 3 and fall in scores 2,4,5, and 6 after the treatment (P<0.05). In 37% of cases, PAI score was >3 and later it decreased to 16 % after re-treatment. Before re-treatment, only 34% obturation was homogenous, after re-endodontic treatment 92.5 % became homogenous.
Conclusion
It was evident that there was clinical resolution of periapical lesions in cases of re-endodontic treatment when compared with initial root canal therapy.
