title: Detection of presence or absence of herpes simplex virus,  Epstein Barr virus and human cytomegalovirus in infected pulp  using a polymerase chain reaction.
abstract: The development of methods to amplify nucleic acids has provided a way of identifying and quantifying infectious pathogens in infected pulp and periapical region. Recent studies have detected human herpes virus in periapical pathosis and periodontitis. The aim of this study is to detect the presence or absence of herpes simplex virus, human cytomegalovirus and Epstein Barr virus in an infected pulp. Ten pulp tissue samples from teeth with irreversible pulpitis and eight control samples were subjected to polymerase chain reaction(Perkin - Elmer Gene Amplification System) for detection of human herpesvirus. The results of this study did not reveal any human herpes virus in both the control and infected pulp tissue samples. According to this study, human herpes virus may not have an entry through the infected pulp to reach the periapical region and may not be a causative organism in the pulp.
