Treponema parvum in the bacteria under the gums of people with periodontitis

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study will collect subgingival plaque samples using sterile paper points and record clinical periodontal measurements from enrolled participants. Samples will be analyzed by quantitative PCR (qPCR) to detect Treponema parvum and estimate its relative abundance in the biofilm. The study will relate T. parvum presence and quantity to clinical parameters such as pocket depth and attachment loss. Findings aim to clarify whether T. parvum is associated with periodontitis and could guide future diagnostic or treatment research.
