Bottom Line: There was significant difference found between immediate and delayed post space preparation in Resilon-Epiphany group (P = 0.0109) as well as in AH plus-GP group (<0.0001).No statistically significant result was found between the two obturating materials when post space was prepared immediately (P = 0.0875).Resilon-Epiphany shows better results when post space is delayed amongst the two whereas in immediate post space preparation there is no significant difference.

ABSTRACT

Aim: To evaluate the influence of immediate and delayed post space preparation on sealing ability of Resilon-Epiphany and Gutta percha-AH plus.

Materials and methods: Eighty extracted permanent maxillary central and lateral incisors were decoronated. Roots canals were prepared and obturated. Samples were divided into four groups depending on the time of post space preparation and obturated material. Group I and II: Immediate and delayed post space preparation respectively with Gutta percha/AH plus as obturating material. Group III and IV: Immediate and delayed post space preparation with Resilon/Epiphany as the obturating material. The samples were kept in methylene blue dye, sectioned and then measured under stereomicroscope and studied under SEM.

Statistical analysis: The data was subjected to statistical analysis using unpaired t-test.

Results: There was significant difference found between immediate and delayed post space preparation in Resilon-Epiphany group (P = 0.0109) as well as in AH plus-GP group (<0.0001). Difference in the sealing ability of the two materials was seen in delayed group (P = 0.0202). No statistically significant result was found between the two obturating materials when post space was prepared immediately (P = 0.0875).

Conclusion: Within the limitations of this study, there was significantly less leakage when post space is prepared immediately in both the groups. Resilon-Epiphany shows better results when post space is delayed amongst the two whereas in immediate post space preparation there is no significant difference.

Mentions: For dye leakage entire root length was painted with nail varnish except apical 4 mm and teeth were immersed in 2% methylene blue dye for 48 hours. All the samples were grooved longitudinally in bucco-lingual direction using a double diamond disc in low speed under constant cooling with distilled water without disturbing gutta-percha filling, they were split with the help of a chisel. All the samples were observed under microscope and 10 samples from each group were randomly selected for scanning electron microscopy (SEM) analysis to qualitatively analyse the leakage. The adaptation of the obturation material to dentinal walls and the interface were examined under SEM at apical 4 mm and microphotographs were taken from 50× to 300× magnification [Figure 1]. Later the obturation material was gently removed from all the samples and the specimens were viewed under stereomicroscope.
