Brief Summary:
Obesity is recognized as a major public health problem. Recent research suggests the involvement of the gut microbiota in the development of obesity. Indeed, obese people are characterized by a dysbiotic intestinal microbiota. Periodontitis are chronic inflammatory oral pathologies linked to an imbalance between the bacterial etiological factor, oral dysbiosis, and the host's immune defenses.They lead to the destruction of the supporting tissues of the tooth and an apical migration of the periodontal attachment system, thus leading to the formation of the pathognomonic entity of the disease, the periodontal pocket.the presence of bacteria of oral origin such as Porphyromonas gingivalis (Pg) has been demonstrated in the adipose tissue of obese patients inducing a chronic low-grade inflammatory response by macrophages which leads to the proliferation of adipocyte precursors predisposing to obesity. The main objective is to assess the average amount of Porphyromonas gingivalis (Pg) in the saliva of obese people (BMI ≥ 30) with periodontitis.

Prospective patient recruitment:
During the patient's visit to the periodontology department, if the patient has periodontitis and has given his non-objection, he will be included in the study. A routine check-up in odontology will then be carried out: complete medical questionnaire (general, hygiene and dietetics), clinical examination (visual examination and statement of periodontal indices), radiological examination. Samples of saliva and periodontal plaque, conventionally taken in current dental surgery practice in the periodontal management of patients, will be used to carry out bacterial assays. CThe saliva samples, which are part of the usual treatment, will be carried out before and after the non-surgical periodontal treatment.
