Abstract
Background:
The present study was conducted to assess quality of root canal (RC) filling before and after RC re-treatment.
Materials and Methods:
Two hundred and thirty-eight radiographs of failed endodontic treatment were assessed. The periapical status of the endodontic treatment was evaluated with periapical index (PAI) scoring system. PAI <3 showed absence and PAI >3 showed presence of periapical lesion.
Results:
There was a statistically significant increase in scores 1 and 3 and decrease in scores 2, 4, 5, and 6 after treatment (P < 0.05). PAI score >3 was seen in 37% before which decreased to 16% after endodontic retreatment. 34.6% obturation was homogenous and 65.4% was nonhomogenous before endodontic retreatment. After endodontic retreatment, 95.2% became homogenous and 4.8% nonhomogenous. The reason for endodontic failure was furcation in 2%, iatrogenic causes in 3%, loss of coronal seal in 16%, periapical pathology in 25%, and inadequate root filling in 54%.
Conclusion:
There was significant improvement and decrease in size of periapical lesions in re-endodontic cases as compared to primary RC treated teeth.
