    Bone has the ability to spontaneously regenerate itself. However, the treatment of critical size bone defects can be problematic. In this study, the healing potential of critical size neonatal mouse parietal defects was evaluated using a scaffold composed of poly (ε-caprolactone) (PCL) and polyvinyl phosphonic co-acrylic acid (PVPA) (referred to as PCL/PVPA). Full thickness 1.5mm circular defects were created in parietal bones obtained from one litter of 4-day-old CD1 mice. The bones were divided into two groups and embedded with PCL or PCL/PVPA scaffolds. The healing response was evaluated using microcomputed tomography, dissecting microscopy, phase contrast microscopy, scanning electron microscopy, and energy dispersive spectroscopy. There was a significant increase (P
