Issues associated with phonetic adaptation to bridgeworks made during different time intervals at clinics of Moscow and its suburbs are elucidated. The defects exposed in the designs of bridgeworks for the anterior maxdlary region affected the articulation ability. On the basis of morphometry research made on the diagnostic models and with respect to their adjustment, an optimal positioning of teeth was chosen for the intermediate stretch (IS) of the prosthesis; an optimal correlation of the IS with the maxillary alveolar process, and, an optimal inclination angle of teeth was selected in regard to the anterior palate region. Speech samples recorded before the old dentures were taken off, in the process of making of temporary plastic dentures and before the permanent bridgeworks were fixed verified, on the basis of the auditing and computer acoustic analysis, the correct choice of parameters in designing the permanent bridgeworks

The changed microflora and lysozyme level in the mouth fluid were studied in 30 patients with carcinoma of the tongue before and after the surgical treatment stage involving the routine general and local medicamental therapy plus 1% water-based chitosan solution of hydrochloric acid administered postoperatively. A lower rate of discharge and a decreased quantitative composition of opportunistically pathogenetic microorganisms were registered in the mouth fluid; besides, a trend was established towards a higher content of lysozyme in the mouth fluid of patients on days 9-11 after radical hemiglossectomy. A quantitative build-up of the normal flora on the average by 1.2 ± 0.8 Ig CFU/ml (p <0.05) and a lack of Candida fungi in inoculation were detected in patients after chitosan therapy, which was not the case in patients after routine therapy alone. The amount of lysozyme in the mouth fluid of group-1 patients (with chitosan) went up after treatment 1.6-fold to reach on the average 44.87 /jg/ml. An average 1.4-fold increase of lysozyme was registered in group-2 patients, the mean value was 35.9 /Jg/ml.

The paper presents a study of adhesive bridgeworks made of ormocer and fibrous materials. Adhesive bridgeworks were made in vitro for the purpose. Strength test was made by loading the bridgeworks' intermediates until visible destructions appear. The study results denote that the adhesive bridgework collapses when a load of 261 ± 5.2 kg is put on its intermediate part. Hence, the breaking load of the adhesive bridgework according to Chedisemov exceeds 3.2-fold the load that can be tolerated by the healthy parodentium

We made comprehensive stomatological examinations of 2216 children and teenagers with different conditions of the parodentium. The cluster analysis was made use of to share the children between groups with the most frequently combined morphofunctional peculiarities of the dentalmaxillary system. The system's anomalies aggravated by a variety of functional impairments complicated by unsatisfactory hygiene of the oral cavity and by unfavorable morphological peculiarities of the mouth vestibule are a more essential risk factor for the development of pathology of parodontal tissues than when only one of them is at work.

Discussed in the paper are the results of a study of biologically active chemical elements contained in blood mixed non-stimulated saliva and hard dental tissues of workers occupied at the Fergana Chemical Fibers Plant (FCFP); modern instrumental methods of the neutron-activation analysis were made use of. Changes in the microelements of blood, saliva and hard dental tissues as well as changes in the enzymatic saliva spectrum (conditioned to a great extent by hazardous occupational factors) were found in FCFP workers.
