Summary

Immediate or delayed immersion and centrifugation of teeth in India ink did not significantly affect apical leakage after root canal obturation. This finding is crucial for understanding factors influencing seal quality in endodontic procedures.

Area of Science:

  • Endodontics
  • Dental Materials Science
  • Biomaterials

Background:

  • Apical leakage is a critical factor in endodontic treatment success.
  • Understanding factors influencing the seal of root canal fillings is essential for preventing bacterial re-infection.

Purpose of the Study:

  • To evaluate the impact of immediate versus delayed immersion time on apical leakage.
  • To assess the effect of passive dye immersion versus centrifuged dye on apical leakage measurements.

Main Methods:

  • Eighty-four extracted human teeth underwent root canal instrumentation and obturation with thermoplasticized gutta-percha and sealer.
  • Teeth were divided into four groups: immediate immersion, delayed immersion (72h), and passive versus centrifuged immersion in India ink.
  • Ink penetration was measured after 72 hours using a stereomicroscope.

Main Results:

  • No statistically significant difference in apical leakage was observed between immediate and delayed immersion groups.
  • Centrifugation of teeth in India ink did not significantly alter leakage measurements compared to passive immersion.
  • The tested variables (immersion timing and centrifugation) did not influence the apical sealing ability.

Conclusions:

  • The timing of India ink immersion (immediate vs. delayed) does not significantly impact apical leakage assessment.
  • Centrifugation during India ink immersion does not significantly affect apical leakage measurements in obturated root canals.
  • These findings suggest that variations in these procedural steps do not compromise the evaluation of root canal sealers.
