ABSTRACT

OBJECTIVE: The objective of this study was to determine if hemodialysis patients who have undergone an invasive dental treatment are at risk of developing infective endocarditis.

MATERIALS AND METHODS: This study was a cohort case-control design and used secondary data collected from the National Health Insurance Research Database of Taiwan. The case group and the control group were each comprised of 19,602 hemodialysis patients. The control group was matched for four variables: age, gender, a medical history of diabetes mellitus, and a cerebrovascular event. After matching, the case group and the control group were each comprised of 19,602 hemodialysis patients. Cox regression analysis determined hazard ratios and 95% confidence intervals.

RESULTS: Patients were followed up at 1 month and 3 months after receiving invasive dental treatment. The results showed the cohort case-control hazard ratio was 0.88 (95% CI, 0.49, 1.57) 1 month after receiving invasive dental treatment. Three months after receiving IDT, the cohort case-control hazard ratio was 1.04 (95% CI, 0.71, 1.52). Hazard ratios did not differ significantly between groups.

CONCLUSIONS: Hemodialysis patients who received invasive dental treatment had no greater risk of developing infective endocarditis than matched control patients. The results of this study should alleviate concerns for hemodialysis patients and dentists about invasive dental treatment procedures. We recommend hemodialysis patients undergo invasive dental treatment when needed.

CLINICAL RELEVANCE: The results of this study showed that invasive dental treatment did not increase their risk of developing infective endocarditis. Hemodialysis patients in need of an invasive dental procedure should be encouraged to undergo treatment if the dentist deems it necessary.
