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.
