Active cytomegalovirus infection in human periodontitis

Abstract

This study used the reverse transcription polymerase chain reaction method to determine mRNA transcription of subgingival human cytomegalovirus (HCMV) in six adult and three localized juvenile periodontitis patients. The oligonucleotide primers targeted the major capsid protein gene to determine active HCMV infection. HCMV major capsid protein transcript was detected in deep periodontal pockets of two adult and two localized juvenile periodontitis patients but not in any shallow periodontal sites. The findings suggest that active HCMV replication can occur in periodontal sites. Further studies are necessary to establish whether periodontal reactivation of HCMV correlates with the initiation or progression of destructive periodontal disease.
