简要总结

The aim of this study is to evaluate the effects of Levodopa-Benserazide drug combination on periodontal status and salivary cytokine levels in patients with Parkinson's disease. The study includes four groups: Parkinson's patients with periodontitis, periodontally healthy Parkinson's patients, participants without Parkinson's with periodontitis, and periodontally healthy participants without Parkinson's. Clinical periodontal parameters (Plaque Index, Gingival Index, Bleeding on Probing, Pocket Depth, and Clinical Attachment Loss) will be recorded. Unstimulated saliva samples will be collected to analyze the levels of TNF-alpha, RANTES, IL-10, IL-13, Total Oxidant Status (TOS), Total Antioxidant Status (TAS), and Malondialdehyde (MDA).

详细描述

Background and Rationale: Parkinson's Disease (PD) is a progressive neurodegenerative disorder characterized by the degeneration of dopaminergic neurons in the substantia nigra. Chronic inflammation and oxidative stress are considered significant factors in the progression of PD. Levodopa (L-DOPA), combined with Benserazide, remains the most effective pharmacological treatment for managing PD symptoms. Periodontitis is a chronic inflammatory disease that leads to the destruction of tooth-supporting tissues and is associated with elevated levels of local and systemic inflammatory cytokines such as TNF-alpha, IL-10, IL-13, and RANTES. Recent studies suggest a bidirectional relationship between systemic inflammation and neurodegenerative diseases. This study aims to evaluate the effects of the Levodopa-Benserazide drug combination on periodontal status and salivary inflammatory cytokine levels in patients with Parkinson's Disease.

Study Design and Setting: This cross-sectional, case-control study will be conducted in collaboration with the Department of Periodontology at the University of Health Sciences, Gulhane Faculty of Dentistry, and the Department of Neurology at Hacettepe University Faculty of Medicine.

Participants and Groups: The study will include a total of 136 participants divided into four groups (n=34 per group):

Parkinson's patients with periodontitis

Periodontally healthy Parkinson's patients
