“…Another study showed that only irrigation was failed to remove this precipitate and instrumentation of the root canal walls, which causes a new smear layer, is needed after formation of this precipitate (Guneser, Dincer, & Arslan, 2017). A recent study reported that no precipitation was occurred when NaOCl and SmearOFF solution—contains CHX and EDTA—used consecutively (Piperidou, Sodhi, Kolosowski, & Basrani, 2018). In this study it was aimed to evaluate the effect of SmearOFF solution on smear layer removal.…”

“…On the other hand, SmearOFF is a one‐step final rinse and the manufacturer claims that it is safe to use with sodium hypochlorite inside the root canal without precipitation (24). Interaction of SmearOFF with sodium hypochlorite on the dentin surface did not result in the formation of a precipitate (25). Therefore, clinicians can obtain antimicrobial benefit without the need for a water/saline rinse (26).…”

The aim of the study was to assess the depth of sealer penetration into dentinal tubules following different final rinses and indirectly evaluate precipitation of irrigating solutions. Methods: 52 extracted maxillary incisors were prepared to size 40/04 with 6% sodium hypochlorite irrigating solution. Following power analysis, teeth were randomly divided into 4 groups (n = 13) according to final rinse. Group 1 – 17% EDTA, Saline and 2% Chlorhexidine solution; Group 2 – SmearOFF™; Group 3 – Qmix®; and Group 4 – saline control. Obturation was performed with gutta percha and resin sealer mixed with rhodamine‐B‐isothiocyanate dye using warm vertical compaction. Teeth were sectioned into apical, middle, and coronal thirds using Buehler diamond saw at 3, 6 and 9 mm from the apex. Sections were examined under confocal laser scanning microscopy, and images were exported to Image J software to measure the maximum depth of sealer penetration circumferentially. Data were analysed using a generalised linear model and post hoc multiple comparisons with significance set at P < 0.05. Group 3 had the highest depth of penetration. There were statistically significant differences between Groups 2 and 3 and control for all sections, Group 1 and control in apical section only. Conclusion: Recently developed final rinses produced higher sealer penetration and more patent dentinal tubules than using EDTA and chlorhexidine sequentially.

Polyurethane (PU) has an eminence potential to be used as a urinary catheter because of its physicochemical properties. The biofilm accumulation on the surface of polyurethane is the biggest hindrance for its usage as a safe and prolonged catheter. Herein, the antimicrobial polyurethane was developed via wet chemistry method. Alkaline hydrolysis using NaOH was used for the generation of hydrophilic (amine) functionality on polyurethane surface. The reactant concentration and reaction time was investigated in terms of good amine functionality. The amine content at optimized condition was found to be ~4 μM/g in 8 h after treating with 10% NaOH. The surface morphology of hydrolyzed polyurethane was characterized using SEM and atomic force microscopy (AFM) technique, which confirmed the formation microdomains on the PU surface due to hydrolysis. Chlorohexidine digluconate (CLX) was used as model drug and CLX was simply incorporated by immersion of the PU in the CLX solution. The immobilization of drug was confirmed using surface chemistry analysis, that is, X‐ray photoelectron spectroscopy and energy‐dispersive X‐ray mapping technique. The cumulative release of drug was observed with varying concentration of drug. Excellent bacteriostatic and bactericidal efficiency were observed for drug immobilized polyurethane against both gram‐positive bacteria S. aureus and gram‐negative bacteria E. coli. The designed CLX‐PU film did not allow the bacteria to adhere on its surface and mitigate the risk of biofilm formation.
