[The sensitivity of clinical indices for periodontal studies]

Some of the clinical indices that are most frequently used in periodontal examinations were tested for sensibility. When chosen with regard to the objective of the respective examinations, they are a great help in evaluating gingival changes. Their shortcomings become manifest especially when compared with objective data (pO2, pH, resistance, volume pulse, responsiveness tests). The requirements that should be met under these conditions are formulated.
