Subgingival irrigants used in Periodontal Therapy

Currently, the focus in periodontal medicine has changed from periodontal surgery to periodontal medicine. The major cause of periodontal disease is the chronic inflammation caused due to the accumulation of dental plaque. Much of the new research is directed at more ergonomic and economic means of plaque control that have the efficacy over traditional methods. Due to the shift in the focus from periodontal surgery to periodontal medicine, the field of plaque chemotherapy is expanding with the new and improved methods of application of antiplaque chemical agents in the interdental and subgingival sites of the intended action. The main purpose for the use of subgingival irrigants is to non-specifically reduce the bacteria and their by products that often lead to initiation or progression of the periodontal disease. Supragingival irrigants help to disrupt and dilute the marginal bacteria and their byproducts, thus helps to prevent gingivitis. Subgingival irrigants interfere with the complex ecosystem that is responsible for the destruction of the periodontium in susceptible host
