“…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.

“… 26 27 The sealer should be labeled with rhodamine B because it allows for the identification of sealers within the dentinal tubules 28 and has no effect on its physical properties, as long as a small amount of dye (less than 0.2%) is used. 5 29 Rhodamine B is known to show a powerful affinity for moisture and has less affinity for calcium in the sealer composition. As a result, it can penetrate more deeply into the dentinal tubules, giving inaccurate results.…”

Objective The aim of this study was to compare the degree of dentinal penetration between an epoxy resin-based sealer applied by using two different filling methods and an ultrasonically activated calcium silicate-based sealer via confocal laser scanning microscopy (CLSM). Materials and Methods Forty-five extracted permanent maxillary premolars with type II canals (Vertucci’s classification) were subjected to the experiment. The root canals were instrumented and distributed randomly into the following three groups: AH Plus + continuous wave technique (AHC group); AH Plus + single cone technique (AHS group); and Endoseal MTA + single cone technique with ultrasonic activation (EMS) group. Each sealer was labeled with rhodamine B dye to allow visualization under CLSM. The sealer penetration depth in each sample was observed at 2 mm and 5 mm from the apex by using CLSM. The data were statistically analyzed by using analysis of variance or Kruskal–Wallis H test according to normality of variable (α = 0.05). Results In all groups, the maximum sealer penetration depth, mean fluorescence intensity, and sum fluorescence intensity values were higher at the 5-mm level than at the 2-mm level. At the 5-mm level, the EMS group showed the lowest value (p = 0.02). At the 2-mm level, there were no statistically significant differences among any of the groups. The AHC group showed higher values than the other groups, but there was no statistically significant difference in the apical area where access of instruments was difficult. Conclusion The AHC group showed the highest dentinal tubule penetration, but had questionable filing efficacy in the apical area, which is of particular importance for the success of root canal treatment. Therefore, in areas such as the apical 2 mm of premolars with type II canals, which are difficult to access by using instruments such as heat carriers, other appropriate approaches may be required accordingly.

“…Moreover, it can be used as an irrigant solution [ 47 , 58 , 59 , 60 ] with less toxicity than sodium hypochlorite or chlorhexidine [ 58 , 59 ], as an intracanal medication by itself [ 61 ], or as an adjunct to calcium hydroxide [ 62 , 63 ]. Chitosan can increase the antibacterial efficacy, bond strength, and penetration of root canal sealers, directly or indirectly [ 48 , 64 , 65 , 66 ]. In addition, some studies suggest that chitosan could be used as an auxiliary for procedures such as apexification [ 67 ], endodontic retreatment [ 68 ], pulp-capping [ 46 , 69 , 70 , 71 ], and pulpotomy [ 72 ], although it was not able to induce apexogenesis in immature necrotic permanent teeth [ 73 ] or to form new mineralized tissues along the root canal walls of immature dog teeth with apical periodontitis [ 74 ].…”

In recent years, nanoparticles (NPs) have been receiving more attention in dentistry. Their advantageous physicochemical and biological properties can improve the diagnosis, prevention, and treatment of numerous oral diseases, including dental caries, periodontal diseases, pulp and periapical lesions, oral candidiasis, denture stomatitis, hyposalivation, and head, neck, and oral cancer. NPs can also enhance the mechanical and microbiological properties of dental prostheses and implants and can be used to improve drug delivery through the oral mucosa. This paper reviewed studies from 2015 to 2020 and summarized the potential applications of different types of NPs in the many fields of dentistry.
