| Summary: | The sympathetic nervous system (SNS) is crucial for stress response regulation and immune modulation. Prolonged SNS activation, often induced by stress exposure, disrupts immune homeostasis and intensifies inflammatory processes, contributing to periodontal disease progression. This study investigates the relationship between SNS activity and periodontitis severity, utilizing salivary biomarkers chromogranin A (CgA) and alpha-amylase (sAA) alongside pro-inflammatory cytokines interleukin-1β (IL-1β) and interleukin-6 (IL-6). Saliva samples from 67 patients, categorized by periodontitis severity (Stages I/II and III/IV), were analyzed using enzyme-linked immunosorbent assay (ELISA). The results revealed significantly higher median levels of CgA (9.45 vs. 3.93 pmol/mL) and IL-1β (257.81 vs. 220.11 pg/mL) in patients with Stage III/IV periodontitis compared with those with Stage I/II, indicating heightened SNS activity and inflammatory response. Correlations between these biomarkers and clinical periodontal parameters, such as probing depth and clinical attachment loss, further support these findings. Despite elevated sAA levels in severe cases, statistical significance was not achieved. IL-6 levels also showed no significant variation across disease stages, although trends aligned with increased severity. This study highlights the interplay between SNA activation and periodontal inflammation, as evidenced by elevated salivary levels of CgA and IL-1β in patients with advanced periodontitis. By integrating neuroendocrine and inflammatory biomarkers into the diagnostic process, clinicians may be able to better identify patients at increased risk for periodontal breakdown and to consider adjunctive interventions such as stress management, thereby supporting more personalized approaches to periodontitis treatment. |
