Aim : The aim of the present study was to evaluate the presence of Cytomegalovirus (CMV) and Epsteinbarr virus -1 (EBV-1)viruses in sub gingival plaque of chronic periodontitis (groupA), aggressive periodontitis patients (group B), periodontally healthy controls (group C) and to compare the clinical parameters between virus negative and positive sites in each of these groups. Materials and Methods : Sixty subjects were included in the study and equally divided into the 3 groups (group A - 20, group B - 20, group C - 20). Sub gingival plaque samples were obtained from the 3 deepest periodontal pocket sites in case of subjects suffering from periodontitis, and from one random bleeding site per quadrant in healthy groups. Clinical parameters like plaque index (PI), gingival index (GI), pocket depth (PD) and clinical loss of attachment (CAL) were recorded. Viral Deoxyribonucleic acid (DNA) was extracted using Proteinase-K DNA Extraction method, and the presence of CMV and EBV-1 was detected by polymerase chain reaction and 2% agarose gel. Results: Results of our study showed a 45% prevalence of CMV and EBV-1 in Aggressive periodontitis cases. Prevalence of CMV in chronic periodontitis and healthy subjects was 20% and 10%, respectively; while for EBV-1 it was 25% and 0%, respectively. In terms of comparison of the clinical parameters with virus presence, both CMV and EBV-1 positive sites showed a significantly higher mean pocket depth compared to virus negative sites. Conclusion: Our studyshowed that the prevalence of EBV1 was higher in chronic and aggressive periodontitis subjects compared to controls and the prevalence of CMV was higher in aggressive periodontitis patients. The virus positive sites showed higher pocket depth compared to virus negative sites.
