Psoriasis has been associated with other diseases, or comorbidities, within which the oral cavity is involved. However, there is no consensus regarding the clinical description. The objective of this study was to establish the oral and periodontal status in a group of patients with Psoriasis vulgaris in relation to markers of clinical severity.

Materials and Methods:

Descriptive, cross-sectional, and observational study. 71 Patients diagnosed with psoriasis at the Hospital Militar Central. The indexes PASI and DLQI to determine their clinical activity were evaluated. We also evaluated serum markers of activity, A direct observation, ganglion palpation, extraoral, intraoral examination, and periodontal clinical index. Chi-squared test for associations was performed, All analyses involved a significance level of 5% and were carried out using the statistical analysis program STATA, version 11.1.


Periodontal disease was present in 70% of our patients with a moderate degree of severity in most cases. The presence of P. gingivalis was detected in 23% of patients, 9% of patients with P. gingivalis presented with severe psoriasis (p: 0.189); of these patients, 55% also had periodontal disease (p: 0.189); although this was not statistically significant. Furthermore, 91% of our patients presented with some form of lesion or anatomical variation in the oral cavity; of these, 28% had a single lesion, 63% had multiple lesions and 81.80% of the subjects showed lesions with strong psoriatic association (p = 0.033), including fissured tongue (60.87%; p = 0.034), angular cheilitis (14.49%; p = 0.03) and oral erythematous lesions (13.04%; p = 0.023).


We did not detect statistically significant associations between the severity of psoriasis and periodontal disease but our findings related to oral changes could have good relevance for this type of patients. Our data indicate the need for multidisciplinary management between the clinician and specialists in periodontics and oral pathology.

"Open access will revolutionize 21st century knowledge work and accelerate the diffusion of ideas and evidence that support just in time learning and the evolution of thinking in a number of disciplines."

Daniel Pesut
(Indiana University School of Nursing, USA)

"It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor."

Jacques Descotes
(Centre Antipoison-Centre de Pharmacovigilance, France)

"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."

Patrice Talaga
(UCB S.A., Belgium)

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."

Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."

Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."

Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."

Richard Reithinger
(Westat, USA)

"Not only do open access journals greatly improve the access to high quality information for scientists in the developing world, it also provides extra exposure for our papers."

J. Ferwerda
(University of Oxford, UK)

"Open Access 'Chemistry' Journals allow the dissemination of knowledge at your finger tips without paying for the scientific content."

Sean L. Kitson
(Almac Sciences, Northern Ireland)

"In principle, all scientific journals should have open access, as should be science itself. Open access journals are very helpful for students, researchers and the general public including people from institutions which do not have library or cannot afford to subscribe scientific journals. The articles are high standard and cover a wide area."

Hubert Wolterbeek
(Delft University of Technology, The Netherlands)

"The widest possible diffusion of information is critical for the advancement of science. In this perspective, open access journals are instrumental in fostering researches and achievements."

Alessandro Laviano
(Sapienza - University of Rome, Italy)

"Open access journals are very useful for all scientists as they can have quick information in the different fields of science."

Philippe Hernigou
(Paris University, France)

"There are many scientists who can not afford the rather expensive subscriptions to scientific journals. Open access journals offer a good alternative for free access to good quality scientific information."

Fidel Toldrá
(Instituto de Agroquimica y Tecnologia de Alimentos, Spain)

"Open access journals have become a fundamental tool for students, researchers, patients and the general public. Many people from institutions which do not have library or cannot afford to subscribe scientific journals benefit of them on a daily basis. The articles are among the best and cover most scientific areas."

M. Bendandi
(University Clinic of Navarre, Spain)

"These journals provide researchers with a platform for rapid, open access scientific communication. The articles are of high quality and broad scope."

Peter Chiba
(University of Vienna, Austria)

"Open access journals are probably one of the most important contributions to promote and diffuse science worldwide."

Jaime Sampaio
(University of Trás-os-Montes e Alto Douro, Portugal)
