The University of Szeged is one of the oldest medical training establishments in Europe. Recently, it has been at the center of attention, as it has proved that a correlation exists between psoriasis patients who smoke, and the adverse effects that the two conditions combined have on the periodontium of the patient. This correlation is so strong that now there is a study that says without a shadow of a doubt that psoriasis patients who smoke are much more likely to catch a bad case of periodontitis.
