[The status and functional characteristics of the organs of the oral cavity in children with chronic gastroduodenitis].

The status and functional characteristics of the oral cavity organs were studied in 85 children aged 7 to 12 with chronic gastroduodenitis with various gastric acid production and in 32 age-matched healthy children. Under study were mixed saliva pH values, oral mucosa temperature, Iakovets and Iasinovskiĭ's tests, nonspecific resistance of the oral mucosa, that were examined over the course of hospital treatment. The findings evidence a higher dissemination and intensity of caries, a worse status of the oral cavity, and a higher incidence of periodontitis in the children suffering from gastroduodenitis as against the reference group. The patients' salivary pH values were found changed, oral mucosa temperature and defense potential reduced, oral mucosa saturation with ascorbic acid insufficient, and leukocyte migration into the oral cavity increased.
