[Algorithm for artificial teeth size estimation according to face morphological features in patients with complete adentia].

The aim of the study was to improve the prosthetic treatment of patients with complete absence of teeth, taking into account the development of an algorithm for determining the size of artificial teeth by the morphometric parameters of the face. The study involved 76 elderly and senile adults with a full adentia of permanent teeth, who turned to the clinic for a prosthetic treatment. The results of examination and orthopedic treatment of this category of patients made it possible to develop an algorithm for determining the size of artificial teeth during prosthetics of dentition defects, taking into account the original correction factors obtained by calculation and analytical methods using mathematical-graphic modeling.

[Variations of oral fluid microbiota in healthy children and adolescents].

The aim of the study was to establish the bacterial and viral associations of saliva and the immune resistance in 127 healthy people of different ages. The analysis sorted out three variants of oral fluid microbiota differing by certain combination of indigenous and facultative microflora. It was found that with age there is a significant increase in the number of adolescents with the third variant of the microbiota, characterized by a decrease in the number of indigenous microflora and increase in opportunistic microorganisms and viruses.

[INVESTIGATION OF BLOOD BIOCHEMICAL INDICES DURING BICYCLE ERGOMETRY].

Our investigations showed that physical work (bicycle ergometry) alters the biochemical status of male volunteers. On the 5th minute of bicycle endometry capillary blood looses significantly glucose and increases magnesium, phosphorus and particularly lactic acid. Creatine phosphokinase activity and trygliceride levels did not deviate much from baseline values.

[Peculiarities of microbiological composition of oral fluid during various stages of orthodontic treatment in children and adolescents].

The article presents the results of analysis of spectrum, the rate of frequency and the amount of microorganisms in oral liquid before the beginning of orthodontic treatment of dental abnormalities and deformations and in its stages (6 and 12 months later). As the result of the study the appearance of pathologic microorganisms Staphylococcus aureus and a great number of conditionally-pathogenic fungi of Candida family and Porphyromonas spp. were determined.

[Evaluation of clinical efficiency of various space maintainers in premature loss of deciduous molars].

The paper presents the results of two years observation of clinical application of three variants of space maintainers in early primary molars loss. Sixty-five children aged 6-12 years were included in the study. The most common problems when using fixed space maintainers is a deformation of intermediate part seen in 58.
