A Spectro Photometric Comparative Evaluation of Apical Sealing Ability of Three Different Sealers; Calcium Hydroxide Based, Resin Based and Zinc Oxide Eugenol Based Sealers

BACKGROUND: The aim of this study was to quantitatively analyze the amount of dye leakage with AH26, Sealapex and Tubliseal sealers in endodonticaly treated teeth. MATERIALS AND METHODS: A total of 36 extracted mandibular molar specimens were divided into three groups; Group I: Sealapex, Group II: Tubliseal, Group II: AH26 with 12 samples in each group. Standard access cavity and biomechanical preparation was done with step back flare technique. Obturations were done using respective sealers in the three different groups. Then, samples were subjected to spectro photometric analysis using a filter of 670 nm. Spectrophotometric analysis was performed to quantitatively analyze the amount of dye leakage with all three sealers. RESULTS: Tubliseal exhibited the least microleakage. In comparison to Sealapex, Tubliseal showed a significant difference. Compared to Sealapex, AH26 showed no significant difference. Comparisons made between Tubliseal and AH26 showed no significant difference. CONCLUSION: In the present study, Tubliseal sealer showed least microleage compared with Sealapex and AH26 sealer.
