| Abstract | ||
| The efficiency of sodium alginate aqueous solutions in different concentrations for the consolidation of bone samples were evaluated in the present work. The bone surface was investigated using a digital light microscope, scanning electron microscope(SEM), and Attenuated total reflection – Fourier transform infrared spectroscopy (ATR-FTIR) in addition to change of color measurement. The results indicated that the total color difference (ΔE) increased by increasing Sodium alginate concentration and was acceptable till 2% polymer concentration. Morphological investigation of the treated samples proved the effect of the aging process on the untreated samples and also the improvement in surface morphology after treatment by sodium alginate at 1% and 2%. ATR/FTIR analysis stated that consolidation materials used led to the chemical stability of the bones in compared with the aged untreated sample | ||
