Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study examines the relationship between serum vitamin D levels and bone metabolism markers-osteocalcin and N-terminal telopeptide (NTx)-in gingival crevicular fluid (GCF) of periodontally healthy and periodontitis patients. A total of 120 male participants (60 healthy, 60 with periodontitis) aged 25-40 were included and categorized based on their serum vitamin D levels.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Recent evidence suggests that vitamin D, a key regulator of bone metabolism, may play a role in periodontal health by influencing bone turnover markers such as osteocalcin and N-terminal telopeptide (NTx). This study aims to investigate the effects of serum vitamin D levels on these bone metabolism markers in gingival crevicular fluid (GCF) of periodontally healthy and periodontitis patients.

A total of 120 male participants aged 25-40 years were enrolled, comprising 60 periodontally healthy individuals and 60 patients diagnosed with periodontitis. Participants were further categorized into subgroups based on their serum vitamin D levels (0-10 ng/ml, 11-20 ng/ml, and 21-30 ng/ml). GCF samples were collected from maxillary premolar and molar sites and analyzed using enzyme-linked immunosorbent assay (ELISA) to measure osteocalcin and NTx concentrations.
