Evaluation of age estimation using alveolar bone images.

Area of Science:

• Forensic Anthropology
• Dental Radiology
• Biometrics

Background:

• Alveolar bone exhibits age-related changes that can be observed in radiographic images.
• Quantitative analysis of these changes can provide insights into aging processes.
• Dental imaging techniques are valuable tools in forensic and clinical settings.

Purpose of the Study:

• To quantitatively assess time-related changes in alveolar bone using 2D radiographic images.
• To develop an age estimation method based on alveolar bone changes.
• To evaluate the utility of panoramic X-rays and CT scans for age assessment.

Main Methods:

• Utilized 238 panoramic X-ray and 140 CT panoramic reconstructed images.
• Applied Procrustes analysis with landmark methods for inter-group comparisons.
• Performed age estimation using antemortem panoramic and postmortem CT images.

Main Results:

• Both panoramic and CT imaging revealed significant age-related alterations in alveolar bone.
• Age estimation using postmortem CT images demonstrated reliable assessment capabilities.
• Quantified changes in alveolar bone were observed across different age groups.

Conclusions:

• Clinically observed alveolar bone changes over time were successfully quantified.
• The study suggests the feasibility of age estimation based on alveolar bone morphology.
• An updatable clinical database of coordinate values could enhance future age estimation accuracy.
