“…This indicates high bond strength of an epoxy resin sealer to root dentin. The adhesive failure was found only in the control group because the dense smear layer along the whole canal inhibited the bond of an epoxy resin sealer and the collagen 32) . The coronal third slices of the specimen were excluded in this study because they were unable to obtain circular shape canal.…”

This study aimed to investigate the effect of epigallocatechin-3-gallate (EGCG) from green tea extract on the push out bond strength of an epoxy resin sealer to root dentin. Seventy single root canal premolars were decoronated and instrumented. The roots were randomly irrigated with different final irrigation protocols (n=16): 17%EDTA (EDTA), 17%EDTA followed by 2.5%NaOCl (EDTA+NaOCl), 17%EDTA followed by 1 mg/mL EGCG (EDTA+EGCG) and 1 mg/mL EGCG (EGCG). Other six root canals were received only 2.5%NaOCl as a control group. One root from each group (n=1) was excluded and prepared for SEM investigation. All root canals were then obturated and horizontally sectioned to perform the push out test. EDTA+EGCG group had the highest bond strength (p<0.05). EGCG group showed higher bond strength than EDTA group (p<0.05). The use of EGCG as a final irrigant significantly increased the push out bond strength of an epoxy resin sealer to root dentin.

“…Endodontic sealers play an important role as they aid sealing the endodontic cavity by filling re-entrances, irregular spaces and dentinal tubules, all areas inaccessible for endodontic instruments, thus improving the adaptation of root filling at the dentin-material interface (4,5). Penetration of endodontic sealers also presents advantages because they are biologically beneficial, due to their antibacterial effects on the infected dentinal tubules (6).…”

The aim of this study was to evaluate the filling effectiveness and dentinal penetration of the sealers AH Plus, Pulp Canal Sealer EWT, Sealapex and MTA Fillapex applied according to the vertical condensation technique using thermoplastic gutta-percha. Forty singlerooted teeth were selected. After chemical-mechanical preparation and root-canal filling, sections of the root (2, 4 and 6 mm from the apex) were obtained and analyzed by stereo microscopy and confocal laser scanning microscopy. Data were tabulated and statistically analyzed. With regard to the assessment of void spaces in the filling material at 2 mm from the apex, the sealers showed similar results, but at 4 and 6 mm from the apex, MTA Fillapex had inferior performance compared to AH Plus (at 4 mm), Pulp Canal Sealer EWT (at 4 and 6 mm) and Sealapex (at 6 mm) (p<0.05). With regard to the penetration into dentinal tubules at 2 mm from the apex, the sealers also showed similar results, but at 4 and 6 mm Pulp Canal Sealer EWT had an inferior performance compared to MTA Fillapex and AH Plus, respectively (p<0.05). All four sealers were found to be similar regarding adaptation of the filling material to the root canal walls, except the MTA Fillapex, which showed failures at 4 and 6 mm from the root apex. With regard to the ability to penetrate into the dentinal tubules, the sealers were found to be equivalent, except for the Pulp Canal Sealer EWT as it had poorer results at 4 and 6 mm compared to MTA Fillapex and AH Plus, respectively.

“…Boutsioukis et al reported that MTA when applied throughout the root canal, becomes very difficult to remove. 44 Bortoluzzi et al also advocated that discolouration is caused by grey MTA due to the presence of a toxic element arsenic when it is applied on the coronal region of the root canal. Therefore, it is suggested to apply MTA only in apical part of root canal.…”

BACKGROUNDThe ultimate goal of root canal treatment is to seal the root canal both apically and coronally through obturation and restoration in order to prevent recontamination of the disinfected canals. Even after root canal treatment, there can be problems due to failure. The major causes of root canal failure are persistence of microbes or entry of microbes through coronal or apical leakage. If the reinfection occurs, in most of the cases surgical intervention is required followed by retrograde filling to achieve hermetic apical seal. Various retrograde filling materials have been advocated but MTA was found to be more appropriate as the literature suggested. However, Biodentine has also been used since last few years. The aim of the retrograde filling is to seal the canal in order to prevent passage of bacteria or their toxins from the canal space into peri-radicular tissues and vice versa. MTA and Biodentine has been shown to have a biocompatible nature and have excellent potential in endodontic use.The aim of this article is to comparatively review the properties such as biocompatibility, sealing ability, antibacterial effect and tissue response in both MTA and Biodentine as root-end filling material.
