Brazil research links oral health to chronic kidney disease risk

Research conducted in Brazil has identified potential links between oral health and chronic kidney disease (CKD). A study by the Unesp Botucatu Medical School found that individuals with poor oral health or those who have lost teeth have a significantly higher risk of developing CKD. Specifically, those who rated their oral health as regular had a 1.63 times higher chance of the disease, while those with poor oral health faced a 2.02 times higher risk. Additionally, losing teeth in both the upper and lower jaws was associated with a 30% increase in the likelihood of CKD.

Conversely, frequent dental hygiene appears to be a protective factor. Individuals who brush their teeth three times a day showed up to a 66% lower chance of developing the disease. Researchers noted that while these associations are strong, further studies are required to confirm a direct cause-and-effect relationship.

In a separate observational study, the Federal University of Ouro Preto (UFOP) analyzed the demographic profiles and oral health knowledge of undergraduate students receiving dental services. The study aimed to characterize the habits and knowledge levels of this population to develop targeted educational materials for better oral health prevention and self-care.
