“…Primary studies have focused on the chemical composition of synthetic bone grafts and scaffolds. Calcium phosphates are conventionally used because they are similar in composition to the inorganic components of human bone [8][9][10][11][12][13][14][15][16]. Although the scaffold composition determines the presence or absence of osteoconductivity, the scaffold structure provides most of the important characteristics for bone regeneration, such as mechanical strength, cell migration, ingrowth of bone and blood vessels, protein adsorption, and nutrient permeation.…”

Generally, ceramics are brittle, and porosity is inversely correlated with strength, which is one of the challenges of ceramic scaffolds. Here, we demonstrate that lamellar septum-like carbonate apatite scaffolds have the potential to overcome these challenges. They were fabricated by exploiting the cellular structure of the cuttlebone, removing the organic components from the cuttlebone, and performing hydrothermal treatment. Scanning electron microscopy revealed that the scaffolds had a cellular structure with walls between lamellar septa. The interwall and interseptal sizes were 80–180 and 300–500 μm, respectively. The size of the region enclosed by the walls and septa coincided with the macropore size detected by mercury intrusion porosimetry. Although the scaffold porosity was extremely high (93.2%), the scaffold could be handled without disintegration. The compressive stress–strain curve demonstrated that the scaffolds showed layer-by-layer fracture behavior, which seemed beneficial for avoiding catastrophic failure under impact. When the scaffolds were implanted into rabbit femurs, new bone and blood vessels formed within the scaffold cells at 4 weeks. At 12 weeks, the scaffolds were almost entirely replaced with new bone. Thus, the lamellar septum-like cellular-structured carbonate apatite is a promising scaffold for achieving early bone regeneration and compression resistance.

Recent advancements in medical applications like detecting bone density in early stages is utmost necessary to save human lives. In this connection finding the amount of mineral or calcium content present in the bone or bone tissue plays a critical role, for that Bone Densitometer are utilizes to find exact Bone Mineral Density(BMD) or bone density values that give information about the structure of bone. Generally, Bone Densitometer gives two forms of results one is T-score and the other is Z-score. If the value of T-score and Z-score is less than the threshold value, then the density of bone is reduced and it will lead to chances of bone fracture. Frequently used bone densitometers are like Dual Energy X-ray Absorptiometry (DEXA) and Radiographic machines like CT and MRI. This review article describes the volumetric and critical review on various techniques exists so far to determine the bone density from these it was observed that CT and MRI are most expensive and it generates more radiation which causes problems for human. Till now in literature the recorded accuracy with these methods are low. Finally, the inference drawn from literature had given a thought thatthe usage of normal X-Ray machine when compared to existed methods may give better accuracy.
