Summary
Preparing post space immediately after obturation with AH Plus sealer maintained a superior apical seal compared to delayed preparation. This finding is crucial for endodontic treatment success and long-term restoration integrity.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- The apical seal is critical for endodontic treatment success.
- Post space preparation can potentially compromise the apical seal.
Purpose of the Study:
- To compare the effect of immediate versus delayed post space preparation on the apical seal.
- To evaluate the influence of timing of post space preparation on sealability using AH Plus sealer.
Main Methods:
- Forty-six single-rooted anterior teeth were instrumented and obturated with warm vertical compaction and AH Plus sealer.
- Post space preparation was performed immediately in one group and after one week in another.
- Apical seal was assessed by measuring dye penetration (India ink) after 72 hours.
Main Results:
- Significant differences in apical dye migration were observed between immediate and delayed post space preparation groups.
- Immediate preparation resulted in a better apical seal compared to delayed preparation.
Conclusions:
- Immediate post space preparation, when using AH Plus sealer and warm vertical condensation, is recommended to maintain a superior apical seal.
- Delayed post space preparation may compromise the integrity of the apical seal.
