[Incidence of malocclusion in children living in areas with high fluoride content in water].

The paper presents the results of orthodontic examination of 503 schoolchildren from the region with high content of fluoride in drinking water. It was found that the prevalence of malocclusions in the examined population subgroup was 71.38 ± 2.02%. The highest rate was revealed in the village of Sosnivka 73.69 ± 3.20% followed by 69.04 ± 3.71% and 70.89 ± 3.61% in the cities of Chervonograd and Dobrotvir. Deep bite was diagnosed in 16.70 ± 1.66% and distal occlusion in 13.32 ± 1.52%. Open bite and mesial occlusion were diagnosed in 7.35 ± 1.17% and 4.38 ± 0.92%. Transversal plane malocclusions were observed in 11.53 ± 1.42%, in 5.37 ± 1.00% cases the cause was narrow dental arch, in 2.48 ± 0.69% - disproportions of the width of the upper and lower dental arches. It was revealed that only 3.58 ± 0.83% of all examined children were receiving orthodontic treatment.

[The morphological changes in the periodontal tissues of outbred white rats during ontogeny]. / Morfologicheskie izmeneniia tkanei parodonta belykh besporodnykh krys v protsesse ontogeneza.

Morphologic studies, carried out by three methods, by van Gieson's, Schmorl's methods, and with the use of 0.1% solution of safranin T, have revealed heretofore unknown structures lying beyond the tooth rudiment of white noninbred rats and disappearing in the course of ontogenesis. The mechanism of the formation of autonomic circulation of the dental follicle, unrelated to the animal body, has been shown. Dental follicular tissues were found grown together with the gingival epithelium and they ruptured during tooth eruption.

[The oral status of children and adolescents undergoing treatment at Truskavets]. / Sostoianie polosti rta u detei i podrostkov, nakhodivshikhsia na lechenii v Truskavetse.

A total of 579 children, treated at the Truskavets health resort for visceral abnormalities were examined. Caries intensity in children suffering from cholecystitis pas made up 5.1 carious teeth, that in gastritis 4.4 teeth, that in liver diseases 4.1 teeth. The incidence of periodontal diseases has made up 57.5, 71.2, and 45.5%, respectively. The oral cavity was found neglected in the majority of children sent to the health resort.

[Dental caries in preschoolers living in a rural locality]. / Karies zubov u detei doshkol'nogo vozrasta, prozhivaiushchikh v sel'skoi mestnosti.

The examination has involved 211 children aged 3 to 6, whose mothers were exposed to pesticides when pregnant. Clinical examinations have shown a much higher incidence rate of caries and intensity of the teeth involvement in the children whose mothers were exposed to pesticides than in those whose mothers had no contacts with these chemicals. To prevent caries in children, one should persuade their mothers to breast-feed their babies during the first year. It is desirable that contacts with pesticides be ceased during pregnancy, i.e. that pregnant women be given other work; if that is impossible reliable protection means should be employed.

[The incidence of acute herpetic stomatitis in children in the Carpathian area]. / Rasprostranennost' ostrogo gerpeticheskogo stomatita u detei v Prikarpat'e.

In the city of Chernovtsy the incidence of acute herpetic stomatitis (AHS) was 8.7%, in Ternopol 9.8% and in Lvov 5.7% of a total of children patients primarily referring to dentists. An age group of 1 to 3 years was most numerous. The increasing incidence of AHS requires preventive measures among which information of population is of a principal value.

[Effect of the rearing in the 1st year of life on dental caries incidence in preschoolers]. / Vliianie vskarmlivaniia na 1-m godu zhizni na porazhaemost' zubov kariesom u doshkol'nikov.

A total of 222 children born after physiological course of pregnancy were investigated. The relation of the pregnancy course and the first-year rearing with dental caries was followed. Pathological pregnancy (toxicoses) and the character of rearing both had a major impact on the caries susceptibility. These factors should be considered in detection of the risk groups in preschool age and in planning preventive and treatment measures. Obstetricians, gynecologists, pediatricians and pediatric dentists should make considerable efforts to prevent and treat the pregnancy complications, ensure sufficient and long-lasting lactation.
