Influence of Periodontal Treatment on Systemic Inflammatory Mediators (Perio-CHD)

October 13, 2016 updated by: Syed Akhtar Hussain Bokhari, Sheikh Zayed Federal Postgraduate Medical Institute

Influence of Periodontal Treatment on Systemic Inflammatory Mediators:hsC-reactive Protein, Fibrinogen and White Blood Cells in CHD Patients

Currently the research issue in establishing the role of periodontal disease (PD) in coronary heart disease (CHD) risk is to define the pathways that lead to cause-effect relationship between PD and CHD. There is no consensus on definition of a periodontal disease case or the threshold level that may give clear indication for this relationship. Periodontal therapy has been used in different studies with the hope that a change in periodontal disease status may modify the factors associated with CHD risk. Many of these studies, on role of periodontal therapy in the reduction of CHD associated risk-factors, were based on small study samples, and very few studies were randomized controlled trials. So a need for large prospective studies is warranted in literature.----------- A single-blind parallel-arm randomized controlled clinical trial was designed to observe the influence of periodontal treatment on serum inflammatory mediators of hsC-reactive protein, white blood cells and fibrinogen in CHD patients.

Hypothesis: Periodontal therapy in CHD patients, by reducing periodontal inflammation, may decrease the host systemic inflammatory burden associated with atherogenic processes.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
