HerPerio: Association of Herpesvirus and Periodontitis
Study Details
Study Description
Brief Summary
A significant influence of the Herpes viruses family in the progression of periodontal disease has been suggested. The aim of this study was to investigate the potential association of four Herpes viruses (HSV-1, HSV-2, CMV and EBV) with periodontal disease using a qualitative test for evaluating the presence or absence of viral DNA in crevicular fluid samples of both healthy periodontal patients and periodontal compromised patients.
Adult patients with healthy periodontium or periodontally compromised attending the Egas Moniz university dental clinic (Almada, Portugal) are eligible to participate The study involves a periodontal diagnosis and collection of unstimulated crevicular fluid from saliva samples.
There will be no direct benefits for patients, but indirect benefit of advancing science in the study of potential involvment of Herpes viruses in periodontitis. No risks of participating are antecipated as the study material and data will be anonymized.
The study runs from the the Cooperativa de Ensino Egas Moniz and is expected to run for 3 months.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Cases Periodontally compromised patients attending the Periodontology Department during periodontal diagnosis appointments at the point of first diagnosis. |
Genetic: Sampe collection
Unstimulated crevicular fluid samples are collected using two sized 35 paper cones per subject, both used in the sampling process. The DNA is extracted from the samples through multiplex PCR at the Egas Moniz Applied Microbiology Laboratory (LMAEM).

| Controls Periodontally healthy patients attending the remaining specialty departments ath the same clinic at the point of first diagnosis. |
