title: Comparison of oral lesion prevalence between renal transplant patients and dialysis patients.
abstract: OBJECTIVE
  Renal transplantation is performed in patients with end stage renal disease as the best treatment plan. However, different complications may occur in these patients due to the direct consequences of the renal disease or drug-induced suppression of the body immune system. The main objective of the present study was to compare different oral lesions in patients receiving renal transplantation with the patients undergoing dialysis referred to two hospitals in Tehran, Iran.
  
  
  METHODS
  In this cross-sectional study, 93 renal transplant patients who had received renal transplant at least 6 months prior to our study, were selected from their records at the hospitals. Furthermore, 93 candidates of renal transplantation were selected as the control group. The patients in both case and control groups underwent oral examinations and the results were analyzed by chi-square test and Spearman correlation coefficient.
  
  
  RESULTS
  At least one oral lesion was found in 30 (32.2%) patients in the renal transplant group and 8 (8.6%) patents in the control subjects. The difference between the two groups was statistically significant (p<0.0001). The most prevalent lesion was xerostomia observed in 20 patients of the renal transplant group and 4 patients in the control group. The odds ratio of cyclosporine and amlodipine and the effect of these in increasing the risk of oral lesions was 1.21 and 1.02, respectively in renal transplant recipients.
  
  
  CONCLUSIONS
  The results of the study showed that renal transplantation significantly increases the risk of related oral lesions. Therefore, renal transplant recipients must undergo regular oral examinations in order to find any suspicious lesion(s) as soon as possible to treat them.
