Comparison of Apical Leakage in Single Cone Obturation Using Bioceramic and Polydimethylsiloxane Sealer

Objectives: To evaluate the comparison of the apical leakage between obturation using Bioceramic sealer (BS) and Polydimethysiloxane sealer (PS).
Methods: Thirty six mandibular premolars were equally divided into two groups and obturated with single cone technique. The sealer used for Group I and Group II were BS and PS respectively. After the obturation, the samples were incubated (37°C, 24 h), sealed with two coats of nail polish except for 2 mm from the apex, immersed in the Indian ink for 7 days, decalcified, dehydrated, and made transparent according to Robertson technique. Dye penetration were evaluated under stereomicroscope. Sample with no dye penetration were given score 0, ≤ 0.5 mm dye penetration were given score 1, 0.051 - 1 mm were given score 2, and > 1 mm were given score 3.

Results: The largest proportion distribution in BS was at the score 1 (55.6%) and in group PS at the score 2 (44.4%)
Conclusions: Bioceramic sealer showed similar apical leakage to Polydimethylsiloxane sealer.
