Abstract
Kidney transplant patients (KTPs) have a potential tendency to develop oral lesions due to the administration of immunosuppressive drugs, but their prevalence is still obscure. The aim of the present study was to investigate the oral clinical findings in a group of renal transplant patients in comparison with age-and sex-matched healthy controls (HCs). Three hundred KTPs who underwent transplantation at least six months earlier and 296 HCs were examined clinically for the presence of any oral lesions. Demographic and additional details regarding medications, systemic diseases and duration after transplantation were recorded. Statistical analysis was performed using the Chi-square test, with significance set at P < 0.05. The prevalence of oral lesions in KTPs was 56.8% as compared with 29.7% in HCs. The most common lesion observed in KTPs was gingival overgrowth (21.8%), followed by candidiasis (17.1%). Coated tongue (15.9%), followed by leukoplakia (11.3%), were common in HCs. Both gingival hyperplasia and coated tongue were significantly related to poor oral hygiene (P < 0.05), but were not significantly related to the immunosuppressive therapy (P > 0.05). The findings of the present study indicate the need for a routine and regular oral health check-up, with emphasis on maintenance of oral hygiene for renal transplant patients.
