Official title
Prevalence of Treponema Parvum in Subgingival Microbiome of Patients With Periodontitis: A Case-Control Study
Overview
The current study primarily aims to evaluate the presence of T. parvum in periodontal health and disease, and its correlation with clinical parameters. Subgingival plaque samples will be collected using sterile paper points then the samples will be analyzed using quantitative polymerase chain reaction (qPCR) to detect T. parvum and estimate its relative amount in the biofilm. The results may help clarify the association between T. parvum and periodontitis.
Primary outcome measures
- Relative abundance of T. parvum in subgingival biofilm [Time frame: At enrollment]
