“…The cleanliness of the root canal wall from the smear layer increases bond strength to dentin and reduces microleakage for sealers by enhancing the sealer penetration into the dentinal tubules resulting in mechanical interlocking to the canal walls [ 8 ]. Several previous studies were in accordance with this study which stated that 0.2% chitosan produced the same bond strength as 17% EDTA [ 34 , 35 ] and greater sealer penetration with a variety of application times [ 36 , 37 ].The advantage of chitosan compared to EDTA as the final irrigation material is chitosan has antibacterial properties, while EDTA has no antibacterial properties [ 16 ], although antibacterial properties of chitosan were not tested in this study.…”

Background/Objectives. Root canal irrigation is a crucial stage during root canal treatment since it can affect the root canal obturation; as a result, the success of root canal treatment can be achieved. The objective of this study is to evaluate the effect of 0.5% chitosan nanoparticles as a final irrigation solution with different application times on the apical sealing ability and the bond strength of root canal obturation. Materials and Methods. Fifty-six premolars were used in this study and divided by two evaluations: 28 teeth for apical sealing ability and 28 others for bond strength. Each study was assigned randomly into two groups of fourteen teeth: Group-1, final irrigation with 17% EDTA; Group-2, with 0.5% chitosan nanoparticles. Each group was further divided into two groups of 7 each: Group-A, final irrigation was applied for 1 minute; Group-B, for 3 minutes. All teeth were obturated with epoxy resin-based sealer and gutta-percha. In the apical sealing ability study, the obturated teeth were immersed in 2% methylene blue and observed under a stereomicroscope (8x magnification). In the bond strength study, the teeth were tested using the push-out technique and observed under a stereomicroscope (40x magnification) to determine the failure type. Data from each evaluation were analysed with two-way ANOVA followed by the LSD test. Results. Final irrigation using 0.5% chitosan nanoparticles produced the same apical sealing ability and bond strength as 17% EDTA (p>0.05). A significant difference occurred between application times (p<0.05). The failure type was observed predominantly as cohesive, and the least was adhesive. Conclusion. Regardless of the final irrigation solution used, 3-minute application time produced greater apical sealing ability and push-out bond strength than 1-minute application time.

“…With regarding to ability of smear layer removal at different level of the root canal, current results of both tested solutions showed maximum smear layer removal at both coronal and middle thirds and the least cleaning efficacy was at apical third and the difference was statistically significant. This result agrees with different studies which evaluated effect of EDTA on smear layer removal (42)(43)(44)(45)(46) . This result may be due to stagnation plane of the residual fluid of irrigant at apical third that attributed to irrigation technique (42) .…”

Purpose: To evaluate the impact of 10% Boswellia sacra water extract (B. sacra) as a final irrigant on smear layer removal consequent to primary irrigation with 2.6% sodium hypochlorite (NaOCl). Material and Methods: Thirty-six palatal &distal roots from extracted maxillary & mandibular molars have being instrumented and categorized into 3 experimental groups depending on the final irrigant used: (12 samples each), Group I: irrigated with 10% B. sacra extract. Group II: irrigated with 17% EDTA. Group III: control group irrigated with sterile saline. Irrigation was performed with 5ml of test substances for 1 minute. Scanning electron microscopic analysis was performed to assess smear layer removal on the coronal, middle, and apical portion for each root canal. Results: no statistically significant difference between using 10% B. sacra extract & 17% EDTA for smear layer removal at the entire root canal levels (P=0.000). However, there was statistically significant difference between tested irrigant (10% B. sacra extract & 17% EDTA) compared to control group. Comparison of the capability to remove smear layer among different root canal levels for each group showed a significant difference in smear layer removal on coronal and apical part for all assessed groups. Conclusion: The current in-vitro study demonstrated that 10% B. sacra water extract have a chelating potential similar to that of EDTA 17%. Boswellia sacra as natural product is a promising chelating agent.

“…According to Mjör et al. (29), the cervical third has a larger number and diameter of dentinal tubules compared with the other thirds, which could favour tagging and mechanical retention of filling material (9,30).…”

This study evaluated the syringe/needle (SN), passive ultrasonic irrigation (PUI) and XP‐endo Finisher (XP) in the removal of Ca(OH)2‐based paste and the bond strength (BS) values of an epoxy resin (AH Plus) and silicate (MTA)‐based sealers to root dentin. Eighty lower premolars were assigned: control group (CT), SN, PUI and XP, and subdivided according to the sealer (n = 10) for BS. SN has the lowest removal followed by PUI and XP. AH Plus had higher BS for CT compared with SN in all root thirds. CT and XP presented similar BS in the apical and middle thirds and higher than SN and PUI. For MTA, similar BS was observed in the cervical and apical thirds, and in the middle third, CT, PUI and XP presented similar values and higher than SN. PUI and XP methods presented higher efficiency in the Ca(OH)2 removal, and the residual Ca(OH)2 provides a reduction in BS of the AH Plus.
