Abstract

Background:  To evaluate coronal microleakage of MTA, Biodentine, Cention-N and Caviton as intraorifice barrier during nonvital bleaching. Materials & method- 40 single rooted maxillary anterior teeth were selected and divided in 4 groups. Group 1 – biodentine (n=10), group 2- MTA(n=10), group 3- cention - N(n=10), group 4- caviton(control)(n=10).root canal treatment was performed with cold lateral condensation technique.3mm intraorifice barrier was given with respective material.Teeth were coated with nail varnish. Sodium perborate and hydrogen peroxide were mixed and placed over barrier for 7 days and cycle was repeated for 21 days. Dye penetration was allowed with 2% basic fuschine dye. Sectioning of teeth were done and analysed under 10x magnification in stereomicroscope. Results –Results showed that there is no significant difference between Biodentine , MTA, Cention – N. But there were more samples with dye penetration in cention-N. Conclusion – Biodentine and MTA can be both used as intraorifice barrier in non-vital bleaching to prevent its complication.

Keywords: Walking bleach, Biodentine, MTA, Cention – N, dye penetration.
