Abstract

The concept of Free radicals and the damage they cause in the biological systems has been getting a lot of attention over the past few years. They have been recently known to be the fore bringer of many inflammatory diseases. Periodontal disease is no exception the accumulation of these various toxic free radicals that are a byproduct of inflammatory change in the different structural components of the periodontium lead to a condition known as oxidative stress, which predispose a positive environment for the aggravation of periodontal disease. Of late there are various therapeutic modalities used for neutralizing this harmful process and can be used as a preventive mechanism for progression of disease. This article is a humble attempt to give an insight to this process and how this knowledge can be applicable for future therapeutic modalities.
