Comparative evaluation of retreatability of three different bioceramic sealers using xylene in root canal retreatment - An cone-beam computed tomography analysis.

AIMS

The study aimed to evaluate and compare the efficacy of xylene in dissolving newer bioceramic sealers versus an epoxy resin-based sealer during endodontic retreatment.

SUBJECTS AND METHODS

Comparing AH Plus to gutta-percha (GP) and CeraSeal (Meta Biomed), Prashanti Bioceramic Sealer, and MTA-Fillapex (Angelus), a total of 72 ( = 18) extracted human permanent teeth with a single root and a single canal were prepared to size F3 and obturated. The ProTaper Universal Retreatment technology was then used to retreat the canals. The percentage volume of remaining filling material was determined by measuring the amount of residual material following retreatment using cone-beam computed tomography.

STATISTICAL ANALYSIS USED

The Tukey's post hoc test and one-way ANOVA were used to analyze the data.

RESULTS

Dissolving sealers with xylene showed varying degrees of efficiency. The results showed statistically significant difference between resin sealer and bioceramic sealers but no statistical difference among bioceramic sealers in the amount of residual after retreatment ( < 0.05). MTA Fillapex had the greatest retrievability, whereas AH Plus had the lowest.

CONCLUSIONS

Bioceramic sealers were more easily dissolved by xylene than epoxy resin-based sealers. The variability among bioceramic sealers suggests that their composition significantly influences their retreatability to consider in endodontic retreatment planning.
