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, 3mm 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.
Objective:The purpose of this study was to compare the depth of dentinal tubule sealer penetration in the apical thirds of severely curved root canals obturated with Resilon/Epiphany self‑etch (SE) or gutta‑percha/AH Plus using scanning electron microscopy.
