There are many factors involved in the etiology of TFO. Trauma from occlusion can be defined as structural and functional changes in the periodontal tissues caused by excessive occlusal forces 3.Injury resulting in tissue changes within the attachment apparatus as a result of occlusal force(s) 2.According to world health organization (WHO), 1978, trauma from occlusion is “damage in the periodontium caused by stress on the teeth produced directly or indirectly by the teeth of the opposing jaw.”.The resultant injury is termed as trauma from occlusion 1. When occlusal forces exceed the adaptive capacity of tissues, tissue injury results.Definitionįollowing definitions are commonly used to describe trauma from occlusion, In the following discussion, we shall try to analyze our current understanding of TFO and its association with inflammatory periodontal diseases. Although many studies have been done to evaluate any relation between progressions of gingival inflammation and trauma from occlusion, conflicting results have been encountered. But, when both the conditions are present simultaneously, it becomes a matter of discussion to designate them as entirely non-associated, partially associated or completely associated conditions. It is generally accepted that trauma from occlusion (TFO) or occlusal traumatism is a separate entity, not related to periodontitis. Periobasics Clinical Periodontology, Recent Posts Introduction to trauma from occlusionĭo abnormal occlusal forces play a significant role in the initiation and progression of periodontal diseases? This question has been our focus of attention for many years.
