Chronic kidney disease is classified as a civilization disease and is being diagnosed in an increasing number of patients. Hypertension and diabetes mellitus often coexist in hemodialyzed patients. The aim of the present study was to identify publications on the oral cavity status of multimorbid hemodialyzed adult patients additionally diagnosed with hypertension and/or diabetes mellitus, published between 2012 and 2022 to establish evidence of the impact of hypertension and diabetes mellitus on the oral status of hemodialyzed patients. Scopus and Web of Science databases were searched. Eight articles were included in the review. In total, 3 articles discussed oral hygiene in hemodialyzed patients, 4 discussed periodontal status, 3 discussed mucosa condition and saliva parameters, and 3 discussed the problem of Candidiasis infections. The conclusions were as follows: there is still a limited number of publications discussing the oral status of hemodialyzed patients diagnosed with hypertension; involved articles have proven that coexisting diseases can influence the oral cavity status of hemodialyzed patients and cause periodontal disorders, lower hygiene status, saliva parameters and make the risk of Candida infections higher.
