Abstract
Periodontal disease is considered an inflammatory disorder that damages tissue through the complex interactions between periodontopathic bacteria and host defense systems. It is likely that the role of reactive oxygen species (ROS) is common to both bacterial- and host-mediated pathways of tissue damage. In recent years, there has been a tremendous expansion in the medical and dental research concerned with free radicals (FR), ROS and antioxidant defense mechanisms. This review is intended to provide a critical up-to-date summary of the field with particular emphasis on the evidence for oxidative damage
and compromised antioxidant status in periodontal diseases.
