Study models

Study models, either conventional or digital, can be useful in the monitoring of gingival recession.

Clinical photographs

Clinical photographs, calibrated by the inclusion of a probe, can also be a useful way of monitoring gingival recession (see figure: Measurement of recession).

Occlusal examination

Occlusal trauma does not cause periodontitis but may, in some circumstances, accelerate periodontal bone loss or increase tooth mobility. Where teeth are drifting or increasing in mobility, occlusal examination is particularly important to investigate the causes of this and to inform a management plan. Occlusal examination and therapy is complex and in many cases will require extended examination and skills.

Testing for the presence of fremitus (i.e. vibration or movement of a tooth when teeth come into contact) may be helpful during the initial examination.

Trauma from the occlusion can increase the complexity of management and periodontal or prosthodontic specialist referral may be necessary.

Further information about occlusal examination and management is beyond the scope of this guidance.

Sensibility testing with cold/hot/EPT

Pulp sensibility tests (both thermal and electric) can be used to determine the status of the dental pulp when pulpal disease is suspected. Sensibility testing may be useful when periodontal bone loss is severe or where an endodontic-periodontal lesion is suspected (see Combined endodontic-periodontal lesions).
