Nanogel-Based Scaffold in EndodonticsAim: The purpose of this study was to evaluate a degradable nanogel-based scaffold with antibacterial content. Methods: This nanogel design consisted of the cross-linker, polyethyleneglycol (PEG 4600) with 3-dimensional network. This polymer degrades over time (~30 days), delivering a controlled release of antibiotic. Amoxicillin was added to the scaffold with 25 wt% (n=26). Nanogel-scaffold only and amoxicillin only were used as controls. Agar diffusion test against E. faecalis was performed at eight time intervals (days 1, 3, 5, 7, 10, 14, 21, 30). One-Way ANOVA was used to compare the antibacterial properties of experimental groups at the eight different times. Results: The antibacterial properties for experimental plates, at the different times, were not significantly different (F=.624, p=.74). Based on the profile, the scaffold-only group showed a smaller inhibition zone compared to the two other groups. The antibacterial profiles for the experimental group and the antibiotic-only group were similar. Conclusion: This particular scaffold presented antibacterial properties. Findings suggest that nanogel-modified scaffolds may have potential use for drug-delivery in endodontics.
