Professional oral hygiene sessions are used to maintain the patient's residual health. Periodontal health, namely tissues supporting the tooth, is measurable through an examination called PSR (Periodontal Screening and Recording) which is performed at each session of oral hygiene in our clinic.
Between the tooth and gingiva there is a space called the biological amplitude and in a healthy state, it can measure from 1 to 3 mm in depth, beyond this value a pathological condition, such as gingivitis or periodontitis, may be present.
Periodontal disease is diagnosed with a periodontal evaluation, by interposing a millimeter probe between a tooth and gingiva and detecting the depth of pocket, where more than 4 millimeters is diagnosed with periodontal disease. When 4mm is identified in a given site during the PSR, it is advisable to consult with a periodontologist and complete a more detailed examination, the Periodontal Charting, which involves recording the sites of the entire mouth, evaluating both bleeding and retraction compared to the previous original condition, this type of examination is often supported by specific radiographic investigations.
