Experimental single controlled study of burned bones: contribution of scanning electron microscopy

Area of Science:

• Forensic Science
• Materials Science
• Biomaterials

Background:

• Understanding bone thermal alteration is crucial for forensic investigations and material science applications.
• Previous studies have explored macroscopic changes in burned bone, but microscopic details require further investigation.

Purpose of the Study:

• To investigate the microscopic alterations in burned bone using Scanning Electron Microscopy (SEM).
• To determine the relationship between controlled heating temperatures and SEM-observed bone morphology.

Main Methods:

• Bone samples were obtained from a maxillary-mandibular block during an autopsy.
• Samples were subjected to controlled heating in a furnace, ranging from 150 to 1150 degrees Celsius for 60 minutes.
• Scanning Electron Microscopy was employed to analyze the microstructural changes in the heated bone fragments.

Main Results:

• Significant microstructural alterations were observed in the bone samples.
• The severity of bone alterations increased progressively with rising temperatures.
• A precise correlation between specific temperatures and observed SEM patterns was difficult to establish.

Conclusions:

• Heating causes discernible microscopic changes in bone structure.
• SEM analysis shows temperature-dependent bone alterations, but precise thermal correlation remains complex.
• Further research may refine the understanding of SEM patterns for thermometry in forensic contexts.
