[Quality of life as the criterion of psychological status of patients with painful dysfunction of the temporomandibular joint].

The quality of life in patients with painful temporomandibular dysfunction and the efficiency of serotonin antidepressants as an element of therapy of these patients were evaluated. The quality of life is decreased in this patient population; they develop hypothymic reactions. Use of serotonin-positive antidepressants appreciably improved the quality of life.

[Complex approach to the problem of individual intolerance of orthodontic constructions made of different materials].

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.

[Potentialities of treating secondary dysthymia with painful dysfunction of temporomandibular joint].

The quality of life and presence of depressions were evaluated in patients with painful temporomandibular dysfunction and the advantages of serotonin antidepressants in combined therapy of this condition were discussed. The findings indicate a decrease of the quality of life and hypothymic reactions in this category of patients. Addition of serotonin antidepressants to combined therapy appreciably improved the quality of life and more rapidly led to reduction of depressive symptoms.

[Histamine-releasing activity of acrylic plastic materials].

The histamine-releasing activity of acrylic plastics (ftorax, stomacryl, ethacryl) used for denture making and maxillofacial prostheses was studied by automated and computer-aided fiber glass method for evaluating histamine release from whole blood basophils. The results indicate that some plastics made by the thermo-polymerization method (for example, ethacryl) are characterized by higher histamine-releasing activity than the plastics made by polymerization using superhigh frequency electromagnetic energy. The method is recommended for preliminary screening of new polymers intended for dentistry and for individual selection of materials with consideration for their safety and strength characteristics.

[Dynamic method for measuring the periodontal area].

The study was carried out on 21 teeth before and after their removal in 9 patients. Mechanical parameters of the dental supporting-retaining system were studied with a two-parametrical periodontometer, which evaluates the tooth mobility and angle of losses, characterizing the internal friction in the tooth-periodontium-bone system. The in vitro area of the periodontium was evaluated using millimeter paper. A direct relationship between the angle of losses and periodontal area was revealed. The authors suggest using a coefficient of propotionateness between the periodontal area and angle of losses; this coefficient does not depend on the tooth mobility and periodontal area.

[Results of measuring tooth mobility by a two-parameter periodontometer].

A new method for evaluating mobility of a tooth and area of its periodontium is suggested. The evaluation of elastic and viscous components of tooth mobility is based on theoretical estimations. Clinical evaluations of tooth mobility were carried out in patients with physiologically normal periodontium making use of a two-parametrical periodontometer. Experiments demonstrated that the ratio of elastic to viscous components of the tooth mobility is proportionate to periodontal area. Two-parameter periodontometer gives data on complete mobility of a tooth and periodontal area.

[Microwave technology for fabricating the bases of plate dentures].

Polymerization of basic acrylic heat-hardened plastic under the effect of UHF exposure is studied. Specimens and standard bases of dentures from Russian acrylic plastic widely used in orthodontics were used in experiment. Plastics polymerized in UHF field and in water bath were compared. Experiments helped develop a method for making removable dentures using microwaves.

[The prevention of intolerance for metal inclusions in the oral cavity].

The authors assessed the informative value of the Nakatani-ryodaraku and I. A.Lednev's methods of electroacupuncture diagnosis used to rule out the development of intolerance to metal inclusions in the oral cavity. Intratok and Eledia devices were used. Preliminary results are encouraging.

[The use of permanent magnets in the orthodontic clinic].

The author reviews published literature on the use of permanent magnets as an alternative to traditional methods of instrumental treatment in orthodontics. Use of magnetic technology in orthodontics should be further researched and improved.

[The effect of metal ceramic crowns on the enzymatic activity of the gingival fluid].

Analysis of the enzymic activities of the gingival fluid obtained round the teeth supplied with metal ceramic crowns with the edges situated on different levels as against the gingival sulcus has revealed an elevation of lactate dehydrogenase, acid and alkaline phosphatases, glutamyl transpeptidase and cholinesterase activities in the gingival fluid from sites where the metal ceramic crown edges were hidden under the gingiva. When the crown edges were on the edge of the gingiva the enzymic activities were found unchanged. The mechanisms of the detected shifts are discussed.

[The characteristics of obtaining functional impressions under unfavorable conditions of the prosthetic bed of the edentulous mandible].

The results of treatment of 680 patients with a drastic atrophy of the alveolar portion of the toothless mandible evidence the advantages of the method for making functional casts, suggested by the authors. This method is based on anatomic features of the denture bed, topography and function of the mimic and masticatory muscles. Making of a preliminary cast is described in detail, as is the preparation of a model, making an individual spoon and the final functional cast.
