Abstract
ObjectiveRegenerative dentistry (RD) is an innovative strategy for treating necrotic teeth and regenerating damaged dental tissue. Biocompatible materials are pivotal for the advancement of RD, and the rising interest in environmental sustainability drives exploration of sustainable materials for dentistry. Bacterial nanocellulose (BNC) has emerged as a promising eco-friendly option and this study aims to assess BNC's suitability as scaffolds for regenerative dentistry applications. MethodsDifferent in vitro methods have been utilized to characterize the properties of BNC scaffolds in regenerative dentistry, such as scanning electron microscopy (SEM) to analyse surface property and porosity, as well as examining their absorption behaviour using phosphate-buffered saline and bovine serum. Dental pulp stem cell (DPSCs) attachment, viability, and proliferation were evaluated using SEM, live and dead, and tetrazolium reduction assays. The odontogenic potential of the scaffold was evaluated using Alizarin Red staining and qPCR (14 and 21 days). ResultsScanning electron microscopy (SEM) images and ethanol displacement method demonstrated the porous architecture of the BNC scaffold with an average porosity of 70.02 ± 4.74% and 50.26 ± 1.43% respectively. The scaffold absorbed 2846.54 ± 258.95 of BSA and 1648.63 ± 50.37% PBS after immersion in solution for 1 h, following pseudo first and second order kinetics. The biocompatibility assay indicated that cell density increased with time and that the scaffold was appropriate for cell adhesion and migration. Moreover, the BNC led to significantly higher mineralization and odontogenic expression compared to the control (BNC in conditioned media). SignificanceBNC showed fast adsorption of bovine serum, allowed DPSC attachment, migration, and odontogenic differentiation. This suggests its suitability as a biocompatible scaffold for triggering in situ mineralized tissue regeneration for regenerative dental applications.
