Abstract

INTRODUCTION:

The aim of this retrospective cohort study was to assess the treatment outcome of orthograde perforation repair using bio-ceramic based materials.

METHODs:

Data from the VCU graduate endodontic practice were analyzed retrospectively. Treatment had been conducted by VCU endodontic residents under the supervision of qualified endodontists during the period from August 2014-December 2020. All cases in which a bio-ceramic based material had been used as a perforation repair material were included. Bio-ceramic based materials included MTA, EndoSequence Root Repair Material Putty and Paste (ERRM), and iRoot BP Plus Root Repair Material (BP-RRM). Perforation repair was performed using a dental operating microscope. Two calibrated examiners assessed the radiographic outcome 6 to 24 months after treatment. The relationship between the pre-operative factors and treatment outcome was analyzed using binary logistic regression analysis.

RESULTS:

Forty-seven cases were initially identified from August 2014 to December 2020. Of these, 24 cases were examined at follow-up (51% recall rate). Overall, 16 of the included teeth (66%) were classified as healed/healing, and 8 teeth (33%) were classified as non-healing. The results of the binary logistic regression analysis showed that none of the 7-pre-operative variables included in the model were significantly associated with the outcome (p > 0.05).

CONCLUSION:

Based on the binary logistic regression model, newer calcium silicate-based materials, ERRM and BP-RRM, are comparable to the clinical performance of MTA in perforation repair procedures.
