To assess and compare the demographic variables, periodontal parameters, cardiac parameters and the expression of periodontal viruses (CMV, HSV and EBV) and inflammatory biomarkers(PTX-3, TLR-2 & TLR-4) in periodontally healthy and generalized periodontitis patients with and without coronary artery disease(CAD).

A total of 240 subjects will be recruited based on the power of the study. The selected subjects will be divided into four groups based on the inclusion and exclusion criteria.

1. GROUP I: 60 healthy subjects ( No generalised periodontitis and no CAD)
2. GROUP II: 60 generalised periodontitis subjects without CAD
3. GROUP III: 60 CAD subjects without generalised periodontitis
4. GROUP IV: 60 subjects with Generalised periodontitis and CAD

Sub-gingival plaque samples will be collected from the subjects of all the four groups. Coronary artery plaque samples will be collected from the patients who were indicated for coronary artery bypass graft surgery (CABG) among group III and group IV.

The demographic variables , periodontal parameters , cardiac parameters , expression of periodontal viruses and inflammatory biomarkers will be measured in all four groups ,

Inclusion Criteria:

1. Patients willing to participate in the study.
2. Patients with 30 to 65 years of age group
3. Both genders
4. Patients should have minimum of 10 natural teeth.
5. In case of group III and IV patients with coronary heart disease to be included.

1. Patients who had undergone periodontal therapy within the previous 6 months.
2. Type I and II Diabetes mellitus
3. Sarcoidosis patients.
4. Carcinoma patients.
5. Rheumatic arthritis patients.
6. Tuberculosis patients.
