RESUMO
The aim of the study was to analyse and compare the most frequent clinical oral symptoms, signs and lesions at end-stage renal disease (ESRD), before kidney transplantation (BKT) and after kidney transplantation (AKT). A total of 35 subjects with ESRD were included, 19 in group A (BKT) and 16 in group B (AKT). Oral lesions were classified according to referent clinical diagnostic criteria: Serum albumins, urea, creatinine and salivary urea, creatinine uremic acid were determined by standard biochemical spectrophotometric methods (Human, Germany). For serum albumin concentration measurement (g/L) the method of bromcresol green assay was used while serum and salivary uric acid determination (µmol/L) was performed according the uricase/PAP method. Serum creatinine concentration was measured (µmol/L) with the Jaffe kinetics method, without deproteinization. Oral signs, symptoms and lesions were higher in group A: metallic taste (O.R. = 6.61/ ± 95% CI : 1.13 < O.R. < 38.69), dry mouth (O.R. = 30/ ± 95% CI : 3.15 < O.R. < 285.71), uremic stomatitis (O.R. = 6.5/ ± 95% CI : 1.47 < O.R. < 28.80 and coated tongue (O.R. = 11.73/ ± 95% CI : 2.31 < O.R. < 59.54). On the other hand, in group B, gingival enlargement (O.R. = 59.5/ ± 95% CI : 7.41 < O.R. < 478.05) was more common. High statistically significant differences were recorded between group A and B for dry mouth and gingival enlargement (p > 0.001). Blood urea, creatinine and albumin levels, as well as salivary urea creatinine and uraemic acid values, were significantly higher in group A. Chances of the appearance of all symptoms, clinical signs and lesions, except gingival enlargement, were greater in group A as against group B. Some of our findings correspond with the stage of the disease and some with the use of medicaments in treatment.
