Abstract

Objective. Determination of the effect of dentin bonding agent (DBA) on the prevention of tooth discoloration produced by mineral trioxide aggregate (MTA). Methods. 50 teeth were endodontically treated and after removal of 3 mm of obturating materials were divided into five groups. In white MTA (WMTA) and grey MTA (GMTA) groups, these materials were placed in root canal below the orifice. In DBA + WMTA and DBA + GMTA groups, DBAs were applied in the access cavity. Then, 3 mm of WMTA and GMTA was placed. The last 10 teeth served as control. All of teeth were restored and color measurement was recorded for each specimen at this time and 6 months later. Results. The mean tooth discoloration in WMTA and GMTA groups was significantly more than DBA + WMTA and DBA + GMTA groups, respectively. There was no significant difference between DBA + WMTA and DBA + GMTA groups and control group. Conclusion. Application of DBA before MTA may prevent tooth discoloration.

Highlights

Mineral trioxide aggregate (MTA) is a biocompatible material with high sealing ability which has been used for various purposes in endodontics, including root end filling, sealing of perforations, treatment of teeth with open apices, and as a pulp capping agent [1,2,3].The color of original MTA was grey and it had a potential of tooth discoloration
There was no significant difference between dentin bonding agent (DBA) + white MTA (WMTA) group and control group in mean discoloration
No significant difference was observed between control and DBA + grey MTA (GMTA) groups
