Bone Regeneration Using N-Methyl-2-pyrrolidone as an Enhancer for Recombinant Human Bone Morphogenetic Protein-2 in a Rabbit Sinus Augmentation Model

<div>Histologic observations in the experimental groups (Masson’s trichrome stain). ((a)–(c)) Overall views of the augmented sinus (original magnification, ×20). ((d)–(l)) High-magnification views of the boxed areas in panels (a)–(c) in each group (original magnification, ×200). Arrowheads, new bone; asterisks, residual bone material.</div>
