“…Dentin pretreatment with SNP positively affected the bond strength of etch-and-rinse and self-etch adhesives in a previous study (16). Also, no negative effect on the interface permeability and bond strength values of fiber posts to intraradicular dentin was observed when silver nanoparticle solution was applied as an irrigation agent in post space prior to fiber post cementation process (6). Zinc oxide nanoparticles (ZNPs) demonstrated potent antibacterial effects against several types of dental plaque bacteria including S. mutans and Lactobacillus (17).…”

“…Bacteria may still persist in the root canal system even after careful chemo-mechanical preparation and obturation of the root canals (5). One proposed method for reducing intracanal bacteria is to use antibacterial irrigants before fiber post cementation (6). However, the antibacterial irrigant should not negatively affect the bond strength of fiber posts to root dentin (6).…”

Effective dentin hybridization which is necessary for the bonding of fiber post to radicular dentin is affected by root regions, irrigants, adhesive systems, and post space preparations (6). One of the most common root canal irrigating solutions is sodium hypochlorite (NaO-Cl) which has antimicrobial properties and the ability of organic tissue-dissolving.…”

“…However, a disadvantage reported for CHX is its probable leaching out of the hybrid layers within 18 to 24 months (10). It could also have some negative effects on the interface permeability and bond strength of fiber post to root dentin (6). Recently, metal nanoparticles have gained popularity in various dentistry fields.…”

Background: This study was undertaken to investigate the effect of intraradicular dentin pretreatment with silver nanoparticles (SNPs), zinc oxide nanoparticles (ZNPs), and titanium oxide nanoparticles (TNPs) on the push-out bond strength (PBS) of fiber posts to root dentin using two types of resin cements. Material and Methods: Eighty single-rooted human premolar roots were randomly divided into eight groups after endodontic treatment and post space preparation, according to the type of intraradicular dentin pretreatment with different nanoparticle solutions (n=20). The groups included no pretreatment (control) and pretreatments with SNPs, ZNPs, and TNPs. Each group was divided into 2 subgroups (n=10) according to cementation: Excite DSC/ Variolink II and ED Primer II/Panavia F2.0. The PBS values were measured in different areas of the post space. The data were subjected to the three-way analysis of variance and Tukey tests (p=0.05). Results: The SNP-pretreated groups showed significantly higher PBS values than the other groups. No significant differences in PBS were noted among the control, ZNP-pretreated, and TNP-pretreated groups. There was no significant difference in the PBS of the fiber posts with respect to cement type. The PBS was significantly lower in the apical region than in the other two regions. There was no statistically significant difference between the PBSs of the cervical and middle thirds. Conclusions: Intraradicular dentin pretreatment with SNPs, TNPs, and ZNPs did not interfere with the PBS of the fiber posts. The best result was obtained for the SNP-pretreated groups for both types of cement. Also, the lowest PBS was found in the apical third of the root canal spaces.
