"Dentis", new glass-polyalkene cement, is not inferior to the modern Russian and foreign analogues in as far as its parameters of adhesion to metal are concerned. Sandblasting is the most acceptable method of preparing the metal surface prior to fixation by "Dentis". The oxide film on the metal surface does not reliably enhance the adhesion of cements and, in some cases, it even reduces it. According to the study results, the "Dentis"cement can be recommended for permanent fixation of fixed dentures in clinical orthopedic stomatology.7

The submicron perftoran emulsion, unlike erythrocytes, can penetrate through narrowed and spasmodic vessels. An experimental study was made in animals for the purpose of defining the above capacity of perftoran. The obtained data demonstrated that the preparation can be used in clinical practice. A group of patients with maxillofacial pathology, who underwent the reconstructive surgery on soft and osseous tissues, was composed. A 4-fold increase in the maximum value of the linear blood flow and in the mean velocity of the volumetric blood flow was registered in one hour after administration of perftoran in small doses. The index of the distal vascular resistance was normalized

The results of mandibuloplasty by the "collapan" biomaterial performed in 1182 patients are described in the paper. Eight groups were composed with respect to a surgical technique; they are: group 1 - the biomaterial was administered post-apically in the treatment of chronic destructive periodontitis (511 patients); group 2 - "collapan" was used in tooth extraction to keep up the osseous tissue volume (82patients); group 3 - "collapan" was used in tooth-preserving procedures (262patients); group 4 - "collapan" was used in immediate intraosseous implantation (132patients); group 5 - delayed intraosseous implantation with "collapan " (Inpatients); group 6 - plastic surgery of the alveolar process in the upper and lower jaws (different modifications) with "collapan" (402 patients); group 7 - reconstruction of the upper jaw with shifting of the maxillary-sinus bottom, "collapan" was used as biomaterial (110 patients); group 8 - surgical repositioning of the lower alveolar nerve including the use of "collapan" (6 patients). According to osteogenesis, reorganization was registered in 211 patients of groups 1,2,3,4 and 8; remodeling of the material into the mature bone by 50% of the initial material volume occurred in 902 patients of groups 5 and 6; and the fibrous or osteoid tissue formed in 69 patients (group 7) after the plastic surgery. "Collapan" is not inferior to foreign biomaterials "Bio- Oss" or "Osteo-Graf. Antibacterial preparations and antiseptics, when added to "collapan", ensure a favorable postoperative course

The research results of bone anatomy of the skull as observed in sagittal synostosis are described in the paper.

Adhesion of the widely spread types of optionally anaerobic and obligatorily anaerobic (including parodontopathogenic) microbes to the basic plastics ofFtorax and Stomacryl were studied experimentally in vitro for the purpose of optimizing the choice of a construction material and its polymerization regime in manufacturing the therapeutic devices for patients with acquired jaw defects.

The authors undertook complex examinations of and treated 57patients with xerostomia concurrent with pathologies of the salivary glands. "Mexidol" was used for treatment: it was administered as the external Novocain block in the salivary glands region. A dynamic follow-up showed a pronounced clinical effect in 67% of patients: the dry mouth syndrome disappeared or diminished; the general health state and sleep improved; pain and swelling in the salivary glands smoothened or disappeared altogether

The results of a study on morbidity involving temporary disablement (TD) among the dentists and related medical personnel, which was conducted in the Belgorod and Samara Regions, are described in the paper. Morbidity accumulated during a period of 3 years by dental orthopedists was evaluated on the basis of sociological questioning. The morbidity rate plus TD is analyzed versus the accumulated morbidity among the dental orthopedists
