Positively charged polyvinylidene fluoride (PVDF) membrane: A potential alternative for absorbent paper points in endodontics
View through CrossRef
Aim The purpose of the study was to evaluate the performance of Polyvinylidene Fluoride (PVDF) as an alternative to paper points (PPs) for endodontic treatments. Methodology The paper points and the PVDF membrane were evaluated for endotoxin binding using Limulus Amebocyte Lysate (LAL) assay. New paper points and the PVDF membrane were evaluated for the presence of endotoxins. Results Absorbency and endotoxin removal with the 0.22µm PVDF membrane was significantly greater than any of the paper points tested. There was significantly more endotoxin found in new paper points compared to the PVDF membrane. Conclusion In conclusion, our study showed that the 0.22μm PVDF membrane was significantly more absorbent and removed more endotoxins than PPs.
