Summary

A new classification of periodontal diseases was created in 2018. the investigators want to know if this clinical classification is based, or not, on a biological reality. To do this, the investigators will collect data from the clinical examination (clinical assessment and radiological assessment) as well as non-invasive samples of subgingival plaque and crevicular gingival fluid (CGF). The subgingival plaque samples will be analyzed to define the microbiotic profiles of the patients and the CGF determined to define their inflammatory expression profiles. These results will then be linked to the diagnosis of severity of periodontitis.

Conditions

  • Periodontitis

Interventions

OTHER

subgingival plaque sample

for subgingival plaque sample, on three affected sites (PD\>3mm) and three healthy sites (PD≤3mm), after supra-gingival plaque removal, sterile endodontic paper points were inserted in selects pockets for 30s to collect the subgingival plaque. The material was transferred into eppendorf tube, one for affected samples and one for healthy samples.

OTHER

CGF sample

each site was sampled with a PerioPaper Strip® (Oraflow), and the volumes collected were measured with a Periotron® (Oraflow). Then samples of affected sites were stowed in an eppendorf tube with 120µL of PBS Tween. The same procedure was performed for the healthy sites
