About this trial
This cross-sectional observational study will compare the gingival crevicular fluid metabolomic profile of 30 adults with periodontitis and 30 periodontally healthy adults. Participants will undergo a periodontal examination and gingival crevicular fluid collection during a single study visit. Targeted metabolomic analysis will be used to identify differences between the two groups and associations with periodontal clinical parameters.
