Aims: To identify the main types of oral lesions associated with psoriasis.
Methods and results: It was a systematic review, based on a search performed in the PubMed/Medline, and Scielo databases, and an associated manual search. Descriptors were selected from DeCs/MeSH and the PICOS strategy (population, intervention, comparison, outcomes, and study design) was applied. Randomized clinical trials and retrospective and prospective studies published from 2000 to 2022 were included, according to the PRISMA parameters (Preferred Reporting Items for Systematic Reviews and Meta-Analysis), registered in the PROSPERO platform. The STROBE quality scale (Strengthening the Reporting of Observational studies in Epidemiology) was also used. One hundred fourteen articles were identified using the search strategy, and nine articles were found in the manual search. Of the sixty-six preselected articles, seven were included in the study. Although it was not possible to identify a specific oral lesion associated with psoriasis, there was a greater occurrence of geographic tongue, fissured tongue, and Candida sp. infection CONCLUSION: Evidence shows that although patients with psoriasis may exhibit lesions in the oral mucosa, they are not specific to this condition. Further epidemiological studies are needed to address the association of psoriasis with possible changes in the oral mucosa.
