Fig. 2.

Relative DNA contributions are increased in diseased gingival crevicular fluid groups. The shaded areas highlight DNA-specific signals in gingival crevicular fluid. The inset traces are an enlarged area of another important DNA band, 1713 cm⁻¹, arising from DNA pair base vibration after Fourier self-deconvolution. Also shown are histograms representing the integrated area (relative DNA content) in the mean spectra from the three groups. ${\mathrm{s}\text{Po}}_2^{-}$, symmetric ${\text{Po}}_2^{-}$; as ${\text{Po}}_2^{-}$, asymmetric ${\text{Po}}_2^{-}$.
