Patients With Periodontal Disease
Conditions
Brief summary
This is a transversal double-centre study. Patients will be recruited from outpatient consultations. They will have buccal inflammation caused by periodontal disease (frequent oral infections, mostly with GRAM (-) bacteria). Three groups of 80 patients, corresponding to slight, moderate and severe periodontal disease, will be formed according to the results of radiological and clinical examinations.
