Abstract

Aim: The purpose of this study was to compare the effect of immediate versus delayed post-space preparation on the apical seal using AH Plus sealer. Materials and Methods: Forty-six single-rooted anterior extracted teeth were instrumented and divided into four groups: Twenty teeth in Groups 1 and 2 and three teeth in Groups 3 and 4. In Groups 1 and 2, each canal was obturated using warm vertical compaction and AH Plus sealer. In Group 1, the post-space was made immediately at the time of obturation, and in Group 2, the post-space was made after placing the teeth in saline at 37°C for 1 week. Groups 3 and 4 represented positive and negative control groups, respectively. The teeth were placed in India ink for 72 h. The teeth were sectioned and the amount of apical dye migration was measured. Results: Significant differences were found between teeth whose post-spaces are prepared at the time of obturation versus 1 week later using warm vertical condensation and AH Plus sealer. Conclusion: Apical seal is well maintained when post-space is prepared immediately after obturation.
