With these concepts in mind, let us review the histology of the periodontal pocket, especially in the area of tissue destruction and healing after the periodontal therapy instituted. The periodontal pocket is described as one which occurred with destruction of the supporting periodontal tissues. Progressive pocket deepening leads to destruction of the supporting periodontal tissues and loosening and exfoliation of the teeth. The suprabony pockets are those which the bottom of the pocket is coronal to the underlying alveolar bone. The infrabony pockets are those which the bottom of the pocket is apical to the level of the adjacent alveolar bone and the lateral pocket wall lies between the tooth surface and the alveolar bone.

Pressure or mechanical resorption
Root resorption associated with pressure or mechanical stimulation may be seen in individuals undergoing orthodontic treatment and can be caused by the application of excessive force. It occurs in the apical region and the resorbed area undergoes repair and remodeling when the cause is removed. It is possible that excess force could cause an aseptic death of the periodontal ligament, followed by inflammation. Pressure may also be a factor in root resorption associated with tumors or, occasionally, cysts involving the roots of teeth. Continue reading

The natural shedding of baby teeth follows the progressive resorption of the roots by cells resembling osteoclasts (Cells that functions in the breakdown and resorption of bone tissue). This physiological resorption may be an inherent developmental process or it may be related to pressure from the permanent successor against the overlying bone or tooth. Continue reading
