Raman spectrometry and dental age estimation
Aim: Dental age estimation is one of the main challenges in forensic dentistry since it contributes to the identification of individuals. Age estimation in adults is less accurate and requires population specific references. Raman spectroscopy is a spectroscopic technique used to observe vibrational, rotational, and other low- frequency modes in a system relying on Raman scattering of monochromatic light. By exploring three points on each tooth (enamel, tooth neck, tooth apex) we sought to find a correlation between noticeable variability on Raman spectra and age. Materials and methods: For this purpose 37 human extracted molars were analyzed by Raman spectroscopy. Each point was recorded with 10 spectrums (100 scans and 500 mW) and PCA regression was calculated. Results: The best age estimation results were achieved on the tooth apex, with an error of predicted and measured age of 2.24 years. Conclusion: There is a significant correlation between variability on Raman spectra and age.
