[Studies of parodontal results obtained for selected teeth and groups of teeth with particular reference to their predictive potential regarding an overall assessment (author's transl)].

With the support of a Cluster Analysis and other statistical methods we have found out the relative efficiency of some periodontal partial recording selections. Overrating or underrating evaluations arise from the registration of periodontal symptoms and signs by partial recording of special teeth or groups of teeth. The results of our investigations have demonstrated the higher quantitative and qualitative coincidence of the RAMFJORDS teeth with the periodontal status as the frontal region of the lower jaw.
