Chronic kidney disease (CKD) appears to be associated with a higher risk of tooth loss, with a higher prevalence of CKD seen among individuals with fewer than 20 teeth, according to researchers in South Korea.
As described in a study published in Renal Failure, a team from the Chonnam National University used data from the Korea National Health and Nutrition Examination Survey (KNHANES) to confirm the association between CKD and number of teeth. Raw data was obtained from the sixth and seventh KNHANES, targeting 16,125 adults aged 40 years or older.
The researchers found that CKD prevalence was significantly higher among individuals with fewer than 20 teeth. After adjusting for age, sex, household income, education, alcohol consumption, smoking, body mass index, hypertension, diabetes mellitus, angina, myocardial infarction, stroke, dyslipidemia, and performance of an oral examination within one year, daily toothbrushing frequency, and hygiene product use, CKD was associated with having fewer than 20 teeth.
“When establishing a comprehensive health prevention and management plan for individuals with CKD, it is thought that efforts to link programs to improve oral health will be necessary,” the authors wrote.
