Microorganisms cause virtually all pathoses of the pulp and periradicular tissues. To effectively treat endodontic infections, clinicians must recognize the cause and effect of microbial invasion of the dental pulp space and surrounding periradicular tissues. Once bacterial invasion of pulp tissue has taken place, both non-specific inflammation and specific immunologic response of the host have a profound effect on the progress of the disease. Knowledge of the micro organism associated with the endodontic disease is necessary to develop a basic understanding of the disease process and a sound rationale for effective management of patients with endodontic infections although the vast majority of our knowledge deals with bacteria, we are now aware of the potential for endodontic disease to be considered associated with fungus and viruses. More than 300 bacterial groups of species of bacteria are today recognized as normal inhabitants of the oral cavity. The bacteria present in the infected root canals include a restricted group of species compared with total flora of the oral cavity.
