Role of absorption coefficient on biomaterials
AbstractThe study of absorption coefficient of various biomaterials have been an important part of research work in the field of radiation biology. Absorption coefficient has an important parameter for study of interaction of radiation with matter. Biomaterials were nonviable materials used in a material device intended to interact with biological systems. An explicit phenomena related to the gamma ray interaction with biomaterials were reported. Results showed that composite resin had lowest absorption coefficient and Zinc oxide had highest absorption coefficient values. We observed that composite resin biomaterial has lowest absorption coefficient than other investigated materials. The biological shielding material could expect lowest absorption coefficient. The significant role of absorption coefficient on biomaterials shown unique nanoscale morphology of biomaterials. Absorption coefficient of biomaterial increased by reducing the sample thickness at nano scale. This absorption phenomenon indicates the role of the unique biological shielding effects on biomaterials. Enhanced γ-ray biological shielding effects of the biomaterials were ZnO, TiO2 , Dycal (DC) and Composite resin (CR). A statistical analysis of the data using an ANOVA test between the groups was signifi-cant difference between the surface micro hardness of these groups p<0.05. Biomaterials were used in Dentistry in such restorative procedures as dental restorations, dentures, dental implants. Therefore, biomaterials could now be used in the fabrication of light weight biomedical safety equipment such as dental materials and devices. Biomaterials can also be used as a bone sub-stitute and pH-values of the material used for health and therapeutic applications.
