    Area of Science:

    • Analytical Chemistry
    • Spectroscopy
    • Materials Science

    Context:

    • Calculus Bovis, a dental calculus, presents distinct color layers.
    • Characterizing these layers is crucial for understanding its composition and formation.
    • Traditional analytical methods may require extensive sample preparation.

    Purpose:

    • To investigate the characteristics of different color layers of Calculus Bovis.
    • To evaluate the applicability of Fourier Transform Infrared Photoacoustic Spectroscopy (FTIR-PAS) for this analysis.
    • To determine if sample pretreatment is necessary and if samples can be reused.

    Summary:

    • Fourier Transform Infrared Photoacoustic Spectroscopy (FTIR-PAS) was employed to analyze the distinct color layers of Calculus Bovis.
    • The study found that FTIR-PAS can effectively differentiate and characterize these layers without any prior sample treatment.
    • Importantly, the analyzed Calculus Bovis samples remained intact and suitable for reuse after the FTIR-PAS analysis.

    Impact:

    • This research introduces a rapid, accurate, and user-friendly analytical technique for Calculus Bovis.
    • The elimination of sample preparation and the possibility of sample reuse significantly streamline the analytical workflow.
    • The findings facilitate more efficient and accessible research into the composition and properties of dental calculus.
