Bioceramic root canal sealers offer superior sealing compared to resin-based options. This study found bioceramic sealers provide better adaptation and less void volume for predictable endodontic obturation.

Area of Science:

  • Endodontics
  • Dental Materials Science

Background:

  • Achieving a hermetic seal in root canal therapy is crucial for long-term success.
  • Limited comparative data exists for contemporary bioceramic and resin-based root canal sealers.

Purpose of the Study:

  • To compare the sealing ability of three bioceramic sealers against two resin-based sealers.
  • To evaluate sealer adaptation and void volume using micro-computed tomography.

Main Methods:

  • Utilized 75 extracted human premolars.
  • Obturated canals with single-cone (bioceramic) or warm vertical compaction (resin-based) techniques.
  • Assessed three-dimensional void volume and sealer adaptation via micro-computed tomography.

  • Bioceramic sealers showed significantly lower total void percentages (0.89–1.24%) than resin-based sealers (1.78–2.15%) (p < 0.001).
  • EndoSequence BC Sealer HiFlow exhibited the best canal wall adaptation and minimal void volume.
  • Bioceramic sealers demonstrated superior sealing efficacy.

    • Conclusions:

    • Contemporary bioceramic sealers offer enhanced sealing ability and canal wall adaptation.
    • Bioceramic sealers support predictable root canal obturation in endodontic therapy.
    • Results support the clinical use of bioceramic sealers.
