Aim: The present study was conducted to evaluate the dentinal wall adaptation ability of different root canal sealers (mineral trioxide aggregate Fillapex [MTA], EndoSequence BC [ESBC] Sealer, and AH Plus) using a scanning electron microscope (SEM). Methods: Forty-five extracted single-rooted human maxillary incisor teeth were selected and divided into three equal groups (n = 15). Working length was established using a #15 K-type file. Canals were prepared with rotary Ni-Ti system to size 30/0.06 or 40/0.06 file using endomotor at 250 rpm, irrigated with 17% ethylenediaminetetraacetic acid, 3% NaOCl, and normal saline solution, and dried with paper points. Prepared canals were obturated with gutta-percha cones using the single-cone technique and appropriate sealers. Specimens were stored in saline solution at 37°C for 48 h and evaluated using a SEM. Unpaired t-test, one-way analysis of variance, and post-hoc tests verified the differences between groups and were considered significant at alpha = 5%. Results: None of the specimens showed a gap-free interface. Gaps compared between MTAF and ESBC did not show any statistically significant differences (coronal [P = 0.9757], middle [P = 0.5464], and apical [P = 0.2136] thirds). However, gaps found at the interface of sealer and dentinal wall in root canals filled with AH Plus showed extremely statistically significant differences when compared with MTAF and ESBC (P < 0.0001). Conclusion: Specimens obturated with MTAF and ESBC Sealer showed smaller gaps on SEM analysis than specimens filled with AH Plus. [ABSTRACT FROM AUTHOR] |
