[Prevalence of secondary deformities of dentition and diseases of temporomandibular joint in the population of Far East].

Epidemiological survey of 1161 indigenous people (I group) and 1000 people came (II group) of the population of Far East in the age over than 20 years was conducted. Established that the deformation of dentitions at diagnosis was found in 22.13% I group, 20.

[Regulatory peptides influence on hypoxia induced tooth germ pathology of new born albino rats].

Intrauterine hypoxia decreased the nucleolar organizator quantity in enameloblasts of newborn albino rats tooth germ. Influence the leu-encepgalin synthetic analog dalargin and non-opiate synthetic leu-encephalin on newborn rats from 2 to 6 day abolished the intrauterine hypoxia affect. The main mechanism of peptide antioxidant effect may be NO system stimulation.

[Effect of intrauterine hypoxia upon newborn albino rat tooth germ cells anabolic activity].

The aim of this study was to examine the intrauterine hypoxia influence on dental hard tissue development. Pregnant rats were exposed in hypoxic environments between day 14 and 19 of pregnancy. The study was performed on 36 newborn albino rats.

[Features of blood's microelement structure of children of Khabarovsk area with dentition anomalies].

The content of microelements in blood corpuscles and in serum of children was defined by atomic-absorption method. Deficiency of essential microelements (iodine, copper, nickel) was established and the content of selenium and zinc in the majority of the surveyed children was raised.

[Antenatal hypoxia influence upon osteogenesis processes].

It was described the results of antenaltal hypoxia's influence upon osteogenesis processes. Reliable changes of the ossification nodus of the lower jaw, that in turn, influenced the frequency of occurrence of dentition anomalies were determined.
