Summary
GuttaFlow-2 and warm vertical compaction best filled internal root resorption defects, showing fewer voids than bioceramic sealers. Micro-computed tomography assessed obturation quality.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- Internal root resorption presents a significant challenge in endodontic treatment.
- Accurate obturation of resorptive defects is crucial for long-term treatment success.
Purpose of the Study:
- To evaluate and compare the effectiveness of different obturation techniques in filling internal root resorption perforations.
- To assess the quality of fill and void percentage using micro-computed tomography.
Main Methods:
- Three-dimensional models of a maxillary central incisor with internal resorption were created using cone-beam computed tomography.
- Four obturation techniques were tested: GuttaFlow-2, NeoSEALER Flo (two variations), and warm vertical compaction with ADSeal.
- Micro-computed tomography was used to quantify the percentage of voids in each obturation group.
Main Results:
- Bioceramic-based sealer groups (NeoSEALER Flo) exhibited a significantly higher volume of voids.
- GuttaFlow-2 (polydimethylsiloxane-based sealer with gutta-percha) and warm vertical compaction techniques demonstrated the lowest void volumes.
Conclusions:
- GuttaFlow-2 and warm vertical compaction are superior techniques for obturating internal resorptive defects.
- These methods provide a more effective seal compared to the tested bioceramic sealer, NeoSEALER Flo.
