Abstract
The objective of this work was to use Raman spectroscopy to assess hard dental tissues after professional oral hygiene treatment and curettage. Spectral changes were identified, and the discriminant model of the specific changes of intensity of the Raman lines (i.e., of dentin, cementum, and enamel), before and after the dental procedures, was developed. This model showed that 6 weeks after the procedures, the hard dental tissues did not have differences and, thus, provided similar conditions for bio-film and dental plaque formation, tissue repair, and new attachment to the surface of the root.
Highlights
In recent years, there has been a sharp increase in the prevalence of periodontal disease
All samples were divided into three main groups: the first group—the teeth diagnosed with chronic periodontitis, removed without prior dental procedures; the second group—the teeth diagnosed with chronic periodontitis, removed six weeks after the professional oral hygiene procedure; the third group—the teeth diagnosed with chronic periodontitis, removed six weeks after the procedure of closed curettage
We considered the average normalized Raman spectra of the studied tissues of teeth of the three main groups (Figure 1)
Summary
There has been a sharp increase in the prevalence of periodontal disease. Periodontal disease is a medical and social problem, as periodontitis causes tooth loss, and infections in periodontal pockets could affect one’s body in general [1]. Periodontal inflammatory diseases represent some of the most common dental problems. The prevalence of periodontal inflammatory diseases among the adult population of Russian Federation has reached 80%, and in people over age 65, it is more that 90% [2]. The course of disease is characterized by increasing severity and intensity and the formation of chronic odontogenic center of infection [3]. Chronic catarrhal gingivitis and chronic generalized periodontitis in the early stages are characterized by low-manifestation or a latent period of infection, making it difficult for prompt diagnosis, causing treatment delays; more that 60% of patients seek treatment for moderate periodontitis [4]
