Authored by Navneet Kaur, Introduction Periodontal disease is a chronic inflammatory process characterized by bacterial etiology. It results in progressive, sitespecific destruction of the supporting tissues of the tooth, resulting in a typical pathological lesion [1]. The main aim of pocket therapy is to eliminate the microbial causative factors of periodontal disease. It is a well-established fact that periodontal diseases are caused by bacteria. Over time, this supra gingival plaque becomes more complex, leading to a succession of bacteria that are more pathogenic. Bacteria grow in an apical direction and become sub gingival, and eventually, as bone is destroyed, and periodontal pocket is formed. In periodontal pockets the bacteria form a highly structured and complex biofilm. As this process continues, the bacterial biofilm extends so far sub-gingivally that the patient cannot reach it during his regular oral hygiene regime. Bacteria within the biofilm are well protecte...
