occlusion is one of the most controversial factors in determining the etiology of periodontal destruction.Traumatic occlusion,a pathologic state of occlusion,could lead to migration of epithelial cuff,localised bone loss and ultimately increased pocket depth.A series of studies have been conducted to evaluate the interactions between periodontal trauma in relation to the initiation,progression and treatment of periodontal diseases.According to the studies done in squirrel monkeys and beagle dogs where jiggling forces were introduced upon existing marginal periodontitis, the dog models showed increased loss of attachment as well as bone levels as compared to monkey models.The results of various studies conducted so far show that traumatic occlusion on a healthy periodontium leads to an increased tooth mobility but no attachment loss.In inflamed tissues however it resulted in more severe inflammation and ultimately bone loss.After the resolution of inflammation,remaining mobility does not result in increased loss of connective tissue attachment.On a clinical level for periodontal disease treatment,decreased emphasis is placed upon management of mobility and increased emphasis upon resolution of inflammation. The main aim of this review is to evaluate the effects of traumatic occlusion in the initiation, progression and management of periodontal diseases.
