“…Moreover, sealer penetration results were in agreement with Aydın et al (2019) (39) , who concluded that EDTA enhanced sealer penetration that was superior to chitosan nanoparticle penetration. On the other hand, previous researches contradicted this study's findings, which reported that 0.2% chitosan provided the same bond strength as 17% EDTA (26,31,56) and similar sealer penetration at the middle and apical thirds (31) .…”

Purpose: To evaluate the effect of 3% green tea extract (GTE) on wettability, depth of penetration, and push out bond strength (PBS) of AH Plus sealer to intraradicular dentin following the use of 0.2% Nano chitosan or 17% EDTA. Materials and methods: Twenty human radicular dentin segments were used for wettability assessment. Following immersion in 2.6% NaOCl solution, samples were divided into 2 groups (n=10) according to the chelating agent used: group I: 0.2% Nano chitosan, and group II: 17% EDTA, each used for 3 min, then the contact angle (CA) was measured. The samples were further immersed in 3% GTE solution for 5 min followed by CA measurement. Twenty human mandibular premolars were prepared up to # X4 ProTaper Next files, then divided into two groups as mentioned previously. Each group was subdivided into two subgroups based on the final flush used (n=5); subgroups A and B; no treatment, and 3% GTE, respectively. Samples were obturated by cold lateral compaction using AH Plus sealer and gutta-percha. PBS was measured using a universal testing machine and sealer penetration was assessed using confocal laser scanning microscopy. Results: Using 3% GTE following the use of 0.2% Nano chitosan significantly increased the wettability and PBS of AH Plus sealer to intraradicular dentin, while its use following 17% EDTA significantly decreased the wettability and PBS of AH Plus sealer. Using GTE increased the maximum depth of AH Plus sealer penetration into the dentinal tubules. Conclusion: GTE improved the wettability, depth of penetration, and push out bond strength of AH Plus sealer to intraradicular dentin treated with Nano-chitosan. Nevertheless, it adversely affected those properties of AH Plus sealer to EDTA-treated dentin.

“…Interestingly, chitosan nanoparticles (CSNPs) were demonstrated to be effective in eliminating the smear layer when utilized as a chelating agent (25) . However, studies concerning the effect of CSNPs on the adhesion of endodontic sealers to RC walls are limited (26) .…”

“…[ 16 ] The nanoparticle size of CS can increase irrigation fluid flow into dentinal tubules, hence increasing smear layer clearance. [ 17 ] Besides, CS polymer is hydrophilic. Thus, it supports close contact with root canal dentin that enables it to be easily adsorbed by the walls of the root canal and supplied deeper to the dentinal tubules.…”

Objectives: The objective of this study is to compare the efficacy of chitosan (CS) nanoparticles (CNPs), citric acid (CA), and ethylenediaminetetraacetic acid (EDTA) in removing the smear layer using two different irrigation needles. Materials and Methods: Palatal roots of 70 maxillary first molars were decoronated, instrumented, and divided into four experimental groups ( n = 20) and one control group ( n = 10). The groups received a final rinse of 0.5% CNPs, 10% CA, 17% EDTA, and distilled water for 3 min. Every group was subdivided into two subsections: IrriFlex ® endodontic or ProRinse ® irrigation needles. Specimens were divided lengthwise and viewed under a scanning electron microscope for evaluation. Statistical Analysis Used: Nonparametric Kruskal–Wallis and Mann–Whitney U -tests were used to compare the results ( P < 0.05). Results: CNPs were as efficient as CA and EDTA as a chelating agent. However, significantly more efficient apically. At all three levels, there was no significant difference between A1 and A2. At the coronal and middle levels, there was a significant difference between B1 and B2, as well as apically between C1 and C2. Conclusions: CNPs remove the smear layer with the same efficiency as other irrigants utilized in this study at coronal and middle levels and more efficiently at the apical levels. IrriFlex ® was more effective than ProRinse ® in removing the smear layer when used with EDTA and CA, while there was no difference when used with CNPs.

“… 75 On the other hand, a recent study found that conditioning dentine with a chitosan-hydroxyapatite precursor nanocomplex prior to tricalcium silicate sealer application resulted in significantly improved mean sealer penetration into tubules. 73 Coupled with its antimicrobial properties, chitosan nanoparticle solutions appear to be promising contenders for novel irrigants, 62 , 76 although it has been suggested that the prolonged treatment time and contact-dependent nature of chitosan nanoparticle-based irrigants are limitations that warrant further research to overcome. 64 …”

Nanotechnology has substantially progressed in the past decades, giving rise to numerous possible applications in different biomedical fields. In particular, the use of nanoparticles in endodontics has generated significant interest due to their unique characteristics. As a result of their nanoscale dimensions, nanoparticles possess several properties that may enhance the treatment of endodontic infections, such as heightened antibacterial activity, increased reactivity and the capacity to be functionalized with other reactive compounds. Effective disinfection and sealing of the root canal system are the hallmarks for successful endodontic treatment. However, the presence of bacterial biofilms and resistance to endodontic disinfectants pose a significant challenge to this goal. This has encouraged the investigation of antibacterial nanoparticle-based irrigants and intracanal medicaments, which may improve the elimination of endodontic infections. In addition, photosynthesizer-functionalized nanoparticles could also serve as a worthy adjunct to root canal disinfection strategies. Furthermore, despite the myriad of commercially available options for endodontic obturation, the “ideal” material has yet to be conceived. This has led to the development of various experimental nanoparticle-incorporated obturation materials and sealers that exhibit a range of favourable physicochemical properties including enhanced antibacterial efficacy and bioactivity. Nanoparticle applications also show promise in the field of regenerative endodontics, such as supporting the release of bioactive molecules and enhancing the biophysical properties of scaffolds. Given the constantly growing body of research in this field, this article aims to present an overview of the current evidence pertaining to the potential translational applications of nanoparticles in endodontics.
