What are the main oral manifestations in heart transplant patients? A scoping review

ObjectiveThe purpose of this scoping review is to evaluate the oral manifestations (OM) of heart transplant (HT) patients undergoing immunosuppressive therapy (IT).Material and methodsA literature search was performed using keywords and MeSH terms related to OM and HT in the Medline/PubMed, Web of Science, Cochrane Library, Scopus, LILACS/BBO databases and in gray literature without language or date restrictions until June 2023. Studies that evaluated HT individuals who used any IT and who reported the occurrence of OM were considered eligible. The results from the search were imported to EndNote Web, and duplicates were removed followed by title/abstract and full-text analysis.ResultsA total of 402 nonduplicated studies were found and 13 fulfilled the criteria and were included in the present review: 10 cross-sectional, 2 cohorts, and 1 clinical trial. The most reported OM were periodontal diseases, including drug-induced gingival enlargement (DIGE), gingival bleeding, gingivitis, and periodontitis. Reported in a minority of studies are oral cancer, opportunistic infections (oral hairy leukoplakia and erythematous candidiasis), enamel defects, and burning mouth.ConclusionConsidering the methodological heterogeneity of the studies analyzed, DIGE is the most commonly observed oral manifestation in HT individuals.
