This study investigates whether there is an association between periodontal disease (gum disease) and chronic neck pain and related functional disability. Participants aged 30-55 years will be grouped based on their periodontal health status (healthy, gingivitis, or periodontitis). Neck pain intensity will be assessed using the Visual Analog Scale (VAS), and functional disability will be measured using the Neck Disability Index (NDI). The study aims to determine whether periodontal disease severity is linked to the severity of neck pain and disability, which may help clarify a potential connection between oral health and musculoskeletal health.
