It is classified as supra bony and infra bony based on its depth in relation to alveolar bone. Mucogingival defect
If the destruction continues unabated apically and reaches the junction of the attached gingiva and alveolar mucosa, the pocket would thus be in violation of the mucogingival junction and would be termed a mucogingival defect. Pocket formation
For the periodontal pocket to form, several elements need to be present. It all starts with the dental plaque . The invasion of the bacteria from the plaque eventually triggers inflammatory response. This in turn results in the gradual destruction of the tissues surrounding the teeth, known as the periodontium. Plaque that has been present long enough to harden and calcify will welcome additional bacteria to the pocket and make it virtually impossible to clean by means of a traditional toothbrush. Continuous destruction of surrounding tissues due to inflammation will lead to degradation of attachment and bone, eventually causing tooth loss. Certain circumstances can worsen the condition and are known as risk factors. These can either be systemic (like diabetes or smoking) or local (like overhanging dental restorative materials causing food trap). It is, therefore, important to manage plaque levels by appropriate oral hygiene measures. The importance of using interdental brushes along with standard or electric toothbrushing should be stressed early on. Early detection of high plaque levels at routine dental visits are found to be beneficial to avoid progression of the pocket formation.
