Q) I teach nephrology at a local PA program, and they want us to integrate dental care into each module. What’s the connection between the two?

Dental health is frequently overlooked in the medical realm, as many clinicians feel that dental issues are out of our purview. Hematuria worries us, but bleeding gums and other signs of periodontal disease are often ignored. Surprisingly, many patients don’t seem to mind when their gums bleed every time they brush; they believe that this is normal, when really, it’s not.

Growing evidence supports associations between dental health and multiple medical issues—chronic kidney disease (CKD) among them. Periodontal disease is one of several inflammatory diseases caused by an interaction between gram-negative periodontal bacterial species and the immune system. It manifests with sore, red, bleeding gums and can lead to tooth loss if left untreated.

Chronic inflammation in the gums is a good indicator of inflammation elsewhere in the body. In and of itself, periodontitis can set off an inflammatory cascade in the body. Poor dentition can also lead to poor nutrition, which then causes a feedback loop, leading to even more inflammation.

Patients with periodontal disease have higher levels of C-reactive protein and a higher erythrocyte sedimentation rate than those without the disease. 1 And a recent study by Zhang et al showed that periodontal disease increased risk for all-cause mortality in patients with CKD. 2

The high cost of CKD from both a financial and personal view makes any intervention worth exploring, as the risk factors are difficult to modify and the CKD population is growing worldwide. We, as medical providers, should reiterate what our dental colleagues have been saying for years: Encourage patients with CKD to practice good dental hygiene by brushing twice a day and flossing daily, in an attempt to improve their overall outcomes. — JT
