Abstract

Drug-induced immunosuppression can predispose kidney transplant patients to different complications including chronic infections and oral lesions. We surveyed oral hygiene habits and conducted detailed periodontal examinations for status assessment.

Appropriate oral hygiene and regular professional control can reduce number and severity of complications, which might be preventive for transplant rejection.

Methods

The investigations were carried out at the Surgery Clinic and at the Dental and Maxillofacial Clinic of the University of Pécs. We compiled a dental questionnaire survey and administered it to 178 kidney-transplant patients, of whom 14 patients volunteered for dental examinations; 14 similar-aged healthy individuals were also recruited as a control group (Table 1). The transplant patients included 7 women and 7 men, whereas the control group included 6 women and 8 men. The average age of the

Results

A significant decrease in the amount of saliva (1.74 ± .29 mL, P = .0002) was found in renal transplant patients compared to the control group (5.39 ± .31 mL). Gingival hyperplasia developed in 57.12% of the transplant patients, which was categorized as stage I in 42.86% of these patients and stage II in 14.26%, based on the hyperplasia. The control group did not develop gingival hyperplasia, indicating a significant difference between the 2 groups (P < .001).

Of the patients suffering from

Conclusion

Results showed a higher incidence of oral lesions in transplant patients, confirming the results of previous studies [12]. With regard to dry mouth, the amount of saliva had significantly decreased in transplant patients compared to the control group. Dry mouth can develop as a result of taking antihypertensives or different drugs acting on the immune system, as well as fluid intake habits [13], [14].

There was no discrepancy in the pH values of the saliva, indicating that the transplanted
