Role Of Phospholipid Transfer Proteins (Pltp) On Endotoxemia Caused By Buccal Inflammation

Study Overview
=================
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.
