RESUMO
Aim: To determine the prevalence of oral lesions (OL) in patients with psoriasis, and compare these findings withthe ones found in patients without this condition.Materials and methods: In the present observational and comparative study, we evaluated 207 patients, with andwithout psoriasis, attending the dermatological consulting service of a concentration hospital in Mexico City. Thepossible association between OL and psoriasis was analyzed through a logistic regression model; the Odds Ratio(OR) and its Confidence Interval (CI) was calculated to be 95%.Results: Two hundred and seven cases were examined (80 with psoriasis and 127 without psoriasis). Of these, 75(36.2%) were men and 132 (63.7%) women. Oral lesions were found in 54 (67.5%) psoriatic patients and in 63 (49.6%)of the comparative group (p <0.012). Fissured tongue (FT) was present in 47.5 % of the patients with psoriasis andin 20.4 % of the group without psoriasis, (OR=3.46, 95% CI [1.14, 10.5], p=0.001). Geographic tongue (GT) waspresent in 12.5 % of the group with psoriasis and 4.7 % in the group without this disease (OR=3.54 95 % CI [1.97,6.79], p=0.028). Likewise, six patients (7.5 %) with psoriasis and 3 (2.36 %) from the comparative group presentedsimultaneously GT and FT (p = 0.0776). The most frequent type of psoriasis was the vulgar psoriasis (90 %), inwhich a higher prevalence of FT (p <0.05) was present. There were no differences between both groups (p>0.05)regarding the use of tobacco. Alcohol consumption was greater (55.0%) among patients with psoriasis than amongthose without psoriasis (26.7%) (p<0.05), but when the association with GT and FT was analyzed, no significantdifferences were found among (..)
