Method & Evidence

AimHow can the design of hybrid scaffolds, mimicking the natural microenvironment of dentin, stimulate cell colonization and proliferation for improved regenerative outcomes?
MethodExperimental Research
ProcedureA novel hybrid scaffold was designed by synthesizing magnesium-doped hydroxyapatite (MgHA) nanocrystals on a gelatin (Gel) matrix to create Gel/MgHA flakes. These flakes were then incorporated into a chitosan (Chit) and Gel polymer blend and processed using controlled freeze-drying to achieve a 3D porous, aligned structure. The scaffold's composition, structure, stability, and ability to support cell adhesion and proliferation were analyzed.
