Occlusal trauma does not initiate periodontitis, and there is weak evidence that it alters the progression of the disease. There is no credible evidence to support the existence of abfraction or implicate it as a cause of gingival recession. Reduction of tooth mobility may enhance the effect of periodontal therapy.

Is there an association between occlusion and periodontal destruction?

Is there an association between occlusion and periodontal destruction?: Yes–occlusal forces can contribute to periodontal destruction.

What is the most common manifestation of occlusal trauma?

The most common clinical feature of secondary occlusal trauma is significant tooth mobility. Other common findings (in addition to those noted with primary occlusal trauma) include drifting and tipping of the teeth.

Can occlusal trauma cause irreversible Pulpitis?

When patients present with signs and symptoms of irreversible pulpitis involving more than one tooth I’m always on the lookout for occlusal trauma. It is not unusual for these occlusal trauma patients to have severe pain with the patient imploring you to “do something”.

What are signs of occlusal trauma?

The signs and symptoms experienced by patients with occlusal trauma are mobility of teeth, temperomandibular joint pain, pain on mastication and periodontal disease. Early diagnosis, proper treatment plan and correction of malocclusion can lead to a successful outcome.

How is trauma occlusion diagnosed?

Clinical diagnosis that occlusal trauma has occurred or is occurring may include progressive tooth mobility, fremitus, occlusal discrepancies/disharmonies, wear facets (caused by tooth grinding), tooth migration, tooth fracture, thermal sensitivity, root resorption, cemental tear, and widening of the periodontal

What does PDL widening mean?

A vertical bone defect develops when bone loss progresses down the root of the teeth in association with a deep periodontal pocket. In its early stage, this phenomenon appears as abnormal PDL widening (Fig. 3).

Can occlusal trauma cause Pulpitis?

89 cases including 100 teeth with pulpitis and apical periodontitis caused by traumatic occlusion were clinically observed. All teeth are caries-free, no any dental disease, and no pocket formation. But there is a distinct evidence of marked occlusal trauma, such as premature contact and occlusal interference.

Can occlusal trauma cause pulp necrosis?

When it is not removed the etiological factor of long duration (occlusal trauma), aseptic pulp necrosis begins by destruction of the microvascular cells, lymphatic and nerve fiber systems.

What is necrotic pulp?

Necrotic teeth are dead teeth — dead because the nerve at the root is dead. This condition, also called necrotic pulp, occurs when the pulp within the tooth no longer has a viable blood supply, so the tissue dies.

What does irreversible pulpitis feel like?

Symptoms of irreversible pulpitis include: Intense pain. Spontaneous pain. Sensitivity to cold that lasts more than 30 seconds.

How is primary occlusal trauma treated?

For a bruxer, the treatment of the patient’s primary occlusal trauma could involve selective grinding of certain interarch tooth contacts or using a nightguard to protect the teeth from normal occlusal forces.

What causes widening of PDL?

PDL widening occurs in trauma from occlusion, but in association with angular bone defects and mobility of teeth. However, in scleroderma, involved teeth are often not mobile and their gingival attachments are usually intact.

Does occlusal trauma cause root resorption?

Occlusal interference associated with tissue lesions caused by occlusal trauma might lead to increased tooth mobility and ongoing root resorption, even after orthodontic forces are removed.
