Tooth mobility and fremitus are hallmarks of occlusal trauma because trauma is the primary cause of clinical attachment loss when occlusal trauma is present.

Question

The statement is correct, but the reason is not correct. This is because both tooth mobility and fremitus , terms that refer to movement of the tooth within the socket, are hallmark s of occlusal trauma. Mobility refers to movement when buccal - lingual lateral pressure or vertical pressure is applied to a single tooth that is not occluded, whereas fremitus refers to movement when teeth are occluded and moved in protrusive and lateral directions. Both are caused by excessive trauma causing destruction of ligament fibers, appearing as a widened periodontal ligament space radiographically and lateral bone resorption. These clinical findings are not related to the apical migration of bone in occlusal trauma; the apical migration of bone and connective tissue, or attachment loss, is a hallmark of periodontitis.
