Abstract
OBJECTIVES: Children and young patients with chronic kidney disease (CKD) are at persistent risk of gingivitis despite usual preventive measures. This clinical study aimed to determine the efficacy of an intensive oral preventive programme (OPP) for young patients with CKD in treating plaque-induced gingivitis modified by systemic factors. METHODS: Young patients with CKD (N = 30) were recruited/randomised to a need-related OPP (n = 15) or treatment as usual (TAU) including mainly motivation and instructions (controls, n = 15) followed by a single intensive prophylactic appointment after 3 months. For the OPP group, depending on the baseline degree of inflammation (PBI) professional mechanical plaque removal, local chlorhexidine gel application and mouth rinse were applied at need-related appointments focussing on local plaque control and reduction in inflammation. RESULTS: After 3 months OPP, lower plaque indices were found (2.62-0.66, p < 0.05) in contrast to TAU (2.32-2.05, p > 0.05) with differences between study groups (p < 0.05). Regarding gingivitis, lower PBI values than baseline were observed in OPP (1.03-0.05, p < 0.05) than TAU (1.15-1.00; p > 0.05); OPP reductions (effect size) were higher than after a single intensive appointment (1.00-0.36; p < 0.05). Degree of immunosuppressive therapy did not differ between groups throughout the study. CONCLUSIONS: Young patients with CKD suffer from generalised gingivitis with increased bleeding sites. This moderate degree of inflammation shows a normal distribution of high and low plaque responders, with no pattern of impact for the degree of immunosuppression. Effectiveness and duration of preventive measures follow a dose-response principle. Therefore, need-related preventive measures should be implemented and maintained in future regular care for CKD patients.
