Clinical outcome of root canal obturation using different based sealers: a retrospective cohort study.

BACKGROUND

This study aimed to assess and compare the performance of root canal treatment obturated either with calcium silicate-based or epoxy resin-based root canal sealers on retreatment cases with periapical lesions.

METHODS

Patients' radiographic data and clinical records were obtained retrospectively from the computerized patient record system. A total of 44 teeth, 28 teeth treated with calcium silicate-based sealer and 16 teeth treated with epoxy resin-based sealer, were included in the study. The mean follow-up period was 11.9 months for calcium silicate-based sealer and 23.6 months for epoxy resin based sealer groups. The outcome was evaluated based on radiographic findings and clinical records of the patients. Chi-square test and Fisher's Exact test were used to examine the differences between categorical variables. An independent samples t-test was used to compare the initial and final PAI differences based on sealer type.

RESULTS

The success rate was 100% for calcium silicate-based sealer and 93.75% for epoxy resin-based sealer. Calcium silicate-based sealer showed a faster healing capacity than epoxy resin-based sealer.

CONCLUSIONS

Both sealers are viable options for retreatment cases, but calcium silicate-based sealer has a faster healing potential.
