Raman Spectroscopy for Assessment of Hard Dental Tissues in Periodontitis Treatment

Area of Science:

• Biomedical Engineering
• Dental Science
• Spectroscopy

Background:

• Professional oral hygiene and curettage are common dental procedures.
• Assessing the long-term effects of these treatments on hard dental tissues is crucial for understanding oral health.
• Raman spectroscopy offers a non-destructive method for analyzing tissue composition.

Purpose of the Study:

• To evaluate hard dental tissues (dentin, cementum, enamel) using Raman spectroscopy after professional oral hygiene treatment and curettage.
• To develop a discriminant model to identify spectral changes in dental tissues.
• To determine the condition of dental tissues six weeks post-procedure.

Main Methods:

• Raman spectroscopy was employed to analyze spectral changes in dentin, cementum, and enamel.
• A discriminant model was developed based on the intensity of specific Raman lines.
• Tissue analysis was conducted before and at six weeks after dental procedures.

Main Results:

• Spectral changes in hard dental tissues were identified and modeled.
• The developed discriminant model indicated no significant differences in hard dental tissues six weeks after treatment.
• These findings suggest similar conditions for biofilm formation, tissue repair, and root surface reattachment.

Conclusions:

• Raman spectroscopy is effective in assessing spectral changes in dental tissues post-treatment.
• Hard dental tissues return to a similar state six weeks after professional oral hygiene and curettage.
• The findings have implications for understanding oral biofilm dynamics and tissue regeneration.
