Brief Summary

Periodontal disease is a multifactorial inflammatory disease of infectious origin. The last epidemiological study concerning periodontitis in France was carried out in 2002-2003 by Bourgeois et al and shows that 95.4% of the patients have a loss of attachment and 82.23% have associated periodontal pockets. The presence of bacteria, mostly Gram-negative anaerobes, is not sufficient to explain the heterogeneity of clinical forms. Indeed, there are different risk factors influencing the frequency and severity of periodontitis. Moreover, the link between systemic pathologies and periodontitis has been widely established: it concerns metabolic syndromes, cardiovascular pathologies, premature pregnancies, autoimmune diseases and Alzheimer disease. Some research has been done on biomarkers found in periodontitis. Among them, the investigators quote the study which took place within the laboratory of Biochemistry - Clinical Proteomics of Pr Lehmann Sylvain by Mertens et al. It is the only study to date that has established an LC-MRM proteomic profile characteristic of periodontitis: indeed, 4 proteins of plasma origin were highlighted thanks to this technology: hemopexin (HEMO), plasminogen (PLMN), apolipoprotein H and α-fibrinogen (FIBA) were correlated with the presence of periodontitis compared to the control group (p\<0.05).

Outcome Measures

Primary Outcomes (1)

  • Comparison of plasma protein concentration between the two groups

    Salivary and crevicular concentrations of each of the plasma proteins (FIBA, PLMN, ApoH, HEMO), measured by ELISA in the case and control groups (in µg/mL). Salivary and crevicular samples will be analyzed using specific ultra-sensitive Meso Scale Discovery (MSD) immunoassay kits.

    1 day

Secondary Outcomes (5)

  • Comparison of plasma protein concentration according to the stages and grades of periodontitis (in case group).

    1 day

  • Comparison of plasma protein concentration according to the presence or absence of diabetes (in case group).

    1 day

  • Quantitative measure

    1 day

  • Comparison of salivary and crevicular protein profiles and protein levels after mass spectrometry analysis between subjects with periodontitis and a control group

    1 day

  • Comparison of level of free nucleosides found in saliva and crevicular fluid by mass spectrometry between subjects with periodontitis and a control group.

    1 day

Study Arms (2)

Group of patients with periodontitis (cases)

EXPERIMENTAL

Patients with periodontitis according to the Chicago 2018 classification criteria

Other: Salivary and crevicular samples

Control group

OTHER

Patients with periodontal health according to the 2018 Chicago Classification

Other: Salivary and crevicular samples

Interventions

The samples will be taken from patients in both groups who meet the selection criteria during consultations at the Montpellier University Hospital's Odontology Department. During these consultations, a sample will be taken after rinsing the oral cavity with a glass of water. The samples will be taken before the periodontal assessment in order to avoid bleeding.

Control groupGroup of patients with periodontitis (cases)
