Salivary Lactoferrin Levels and Polymorphisms in Down Syndrome Individuals with Periodontitis.

ABSTRACT: Background/Objectives: Lactoferrin, a protein involved in the immune response, plays a significant role in the etiopathogenesis of periodontitis in the general population. This cross-sectional study aims to determine the salivary concentration of lactoferrin in Down syndrome individuals with periodontitis. Methods: A convenience cohort of 76 Down syndrome individuals was established, including 34 with periodontitis, 29 with gingivitis, and 13 with healthy gums. Unstimulated saliva samples were collected and processed to quantify the lactoferrin concentration using the Human Lactoferrin ELISA kit, the total protein concentration (bicinchoninic acid assay [BCA]) using the BCA Protein Assay Kit (Pierce, Rockford, IL, USA), and the lactoferrin/BCA ratio. Additionally, the Lf rs11
