[Complex approach to the problem of individual intolerance of orthodontic constructions made of different materials]. / Kompleksnyi podkhod k probleme individual'noi neperenosimosti stomatologicheskikh konstruktsii iz razlichnykh materialov.

The problem of intolerance of materials used in dentistry is reviewed in brief. Characteristic situations when this intolerance manifests are described. Approaches (practical and organizational) which can help reduce the incidence of individual intolerance of dentures and materials used in dentistry are outlined. Methods for individual selection of materials are analyzed. The possibility of using electropuncture methods for this purpose is demonstrated. Arguments in favor of creating a special laboratory for studies of specific problems of dentistry are presented and the list of problems to be solved by this laboratory is offered.

[Comparison of the effectiveness of various types of therapy]. / Sravnenie éfektivnosti razlichnykh vidov terapii.

The paper deals with the analysis of one of the most characteristic problems in medical statistics,--comparison of the efficiency of various therapies (including those with different drugs) from clinical evidence; it gives a detailed account of the applied issues--identification of homogeneous groups and obtaining the estimates of distributed characteristics) of the required accuracy. Standardly, the best agent is identified, by comparing the mean values of the distributed characteristics. Such an approach cannot be considered satisfactory for some reasons. To arrive at a conclusion that it is advisable to introduce a new drug or a new treatment, the appropriate distributions should be more fully compared. A complete analysis of all these aspects has been made on a common basis and a general scheme of their practical decision has been identified.
