| Statement of the Problem: Tooth color changes followed by treatment with bioceramic materials is always a matter of concern. In this article ,NFC as a new ceramic base material assessed for its ability to change the color of teeth. Purpose: The aim of the present in vitro study was to compare tooth discoloration that occurs in human teeth filled with ProRoot WMTA (DENTSPLY Tulsa Dental Specialties, Tulsa, OK) or NFC over the course of 3 months. Materials and Method: Thirty human intact premolars obtained and the root of all teeth was removed by horizontally cutting them about 2 mm below the cementoenamel junction, the pulp tissue was removed afterwards using a barbed broach (Mani, Tokyo, Japan).The teeth were randomly divided to 3 groups (n= 10 teeth per group);control (no material), ProRootWMTA and NFC. The experimental materials were condensed into the crowns and the tooth end sealed with light-cure glass ionomer cement (GC Corporation, Tokyo, Japan).Color was assessed at TBL: baseline (after preparation of the cavities but before placement of the materials), TPO: immediately after placement of the filling material and provisional restoration, T4: after 4 weeks of storage, and T12: after 12 weeks (3 months) of storage. Result: Discoloration was evident in all teeth, immediately (TPO) after applying MTA and NFC. The highest ΔΕ was noted in WMTA at 3 months, followed by NFC, but there was no significant difference between thediscolorations induced by these two materials. Conclusion: There was a similar level of clinically observable tooth discoloration detected using either WMTA or NFC. | ||
