[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.

[Device for studying and recording threshold values for tactile sensitivity for periodontal tooth receptors]. / Ustroistvo dlia issledovaniia i registratsii porogovykh znachenii taktil'noi chuvstvitel'nosti periodontal'nykh retseptorov zuba.

The paper gives data on a new original device and relevant methods for determining the threshold values of tactile sensitivity of periodontal receptors. Methods for studies, the arrangement of the device, and its control are fully described. The use of the device makes it possible to judge about the time course of changes in the periodontium in parodontium pathology and may render a considerable assistance in tooth prosthesis.
