[Association between periodontal abnormality phenotypes based on previous oral records and heart failure-related events in patients with type 2 diabetes mellitus: implications for nursing assessment].

Researchers examined whether periodontal abnormalities in diabetic patients predicted heart failure events during follow-up. While oral health indicators correlated with heart failure outcomes, this association weakened substantially when kidney function was considered, suggesting oral abnormalities reflect broader systemic health rather than independent heart failure risk.
