Improvement of salivary biomarkers vitronectin and fetuin-A levels in periodontitis patients with coronary artery disease post scaling and root planing.

Introduction: Two biomarkers that are gaining attention for their roles in the progression of both periodontal and cardiovascular diseases are vitronectin and fetuin-A. This study evaluated vitronectin and fetuin-A expression in saliva samples of periodontitis (P) patients with and without coronary artery disease (CAD) after scaling and root planing (SRP).

Methods: Sixty patients were divided into three groups: PH + SH (periodontally and systemically healthy), P (stage II/III grade B periodontitis), and P + CAD (periodontitis with CAD). Demographic, periodontal, and cardiac parameters were recorded. Unstimulated saliva samples were collected at baseline (day 0) and after SRP. On day 90, periodontal parameters and vitronectin/fetuin-A expression were reassessed.

Results: P + CAD patients had higher age, weight, BMI, and lower income (p < .001, .025, .002, < .001, respectively), along with elevated plaque index, bleeding on probing, probing pocket depth, and reduced clinical attachment levels (p < .001). Vitronectin was elevated, while fetuin-A was lower in P + CAD, but both improved post-SRP (p < .001).

Conclusions: Enhanced vitronectin and fetuin-A levels post-SRP indicate their potential as biomarkers and therapeutic targets for both periodontal and CAD.
