This study aims to investigate the effects of adding nano-hydroxyapatite (nHA) electrospun polycaprolactone (PCL) membranes for use in dental root regeneration. Porous containing varying amounts nHA (0, 1, 1.5, and 2.5 wt%) were fabricated using electrospinning method. The physicochemical, mechanical, biological properties evaluated. synthesized particles had an average size 52 nm. Electrospun exhibited uniform fibrous morphology with porosities ranging from 56% 86%. Cyclic thermal stress (5°C-50°C) improved mechanical composite membranes, resulting a decrease ultimate tensile strength (UTS) pristine PCL 3 ± 0.12 MPa 1.7 0.11 MPa, while UTS 1.5% increased 3.3 0.30 4.18 0.28 MPa.

ABSTRACT To examine natural bone's bioelectrical traits, notably its piezoelectricity, and to look into how these characteristics influence bone growth repair. In the context of exploring potential piezoelectric biomaterials, such as biopolymers bio‐ceramics, towards orthopedic regeneration applications, research seeks evaluate significance piezoelectricity‐driven osteogenesis. The paper reviews recent on electrical dielectric properties, surface polarization/electrical stimulation effects interacting with cell activity effectiveness biomaterials support tissues' regenerative process. study includes a number materials, collagen, polyvinylidene fluoride (PVDF) barium titanate. applications organic polymers, polymers are particularly highlighted. Piezoelectric being shown in studies enhance cellular metabolism vitro well promote tissues vivo, especially when paired electric field or interface polarization. bio‐ceramics like magnesium silicate titanate, collagen PVDF, have possibilities for applications. However, there several challenges regarding manufacturing specific compositions having desired properties. This review highlighted special emphasis bioceramics. Therefore, types materials huge because they can mimic properties allow better advances tissue engineering medicine. date, little is known about their mechanism action, modifications needed improve efficacy clinical uptake.
