Oral Hygiene and Systemic Biomarkers in Polycystic Ovary Syndrome: Exploratory Phenotype-Specific Associations with Salivary Zonulin

Background/Objectives: Polycystic ovary syndrome (PCOS) is heterogeneous, and oral hygiene indices may not capture the microbial and inflammatory features relevant to different phenotypes. We evaluated oral hygiene, salivary microbiota, salivary zonulin, and systemic biomarkers in classical PCOS and non-classical PCOS (Rotterdam phenotypes C and D).
