[Characteristics of fungi and attempts of their elimination from the oral cavity in children treated with orthodontic appliances]. / Charakterystyka grzybów i próba ich wyeliminowania z jamy ustnej dzieci leczonych aparatami ortodontycznymi.

Microbiological evaluation of oral cavity was performed in 112 children, aged 6-18 years, with retrogenic defects (group I) and other defects (group II). The material for microbiological investigation consisted of contents of oral cavity cultured on the Sabouraud broth. Isolated abacterial strains of fungi were differentiated according to their morphological and biochemical properties. Among isolated fungi, independently of the bite defects and age of children, highest percentage of strains of Candida albicans was noted. Remaining species represented genus Candida (C. glabrata, C. guilliermondii, C. krusei, C. parapsilosis, C. pseudotropicalis, C. zeylanoides), Geotrichum (G. candidum), Rhodotorula (R. rubra) and Trichosporon (T. cutaneum). Fungi were present in oral cavity in 45% (age 6-8 years) and 36.4% (age 9-18 years) of group I patients. In group II these percentages were respectively 15.2 and 58.7. In control groups occurrence of fungi was 3-4 times lower. Despite application of disinfectants and treatment with nystatin, frequency of isolation of fungi did not change.

[Qualitative and quantitative assessment of occlusion in a selected group of children]. / Jakosciowa i ilosciowa ocena zgryzu wybranej grupy dzieci.

The occlusion of 102 children from the Province of Krosno was assessed by means of the diagnostic principles of Orlik-Grzybowska and a scoring system of Masztalerz. The complex of morphological-functional features proper for age was found in 30.39% of children, while malocclusion was diagnosed in 69.61% of them. On the other hand, in the point score evaluation normal occlusion was found in only one child. This indicates a lower sensitivity of the qualitative assessment of occlusion. In the studied group of children posterior malocclusions were most frequent--27.45%, and crowding was second in frequency--26.47%. The occurrence of malocclusion was increasing, from 57.5% in 1966 to 69.61% in the present study which points to a need for extending the orthodontic health care in prevention and treatment even in regions with good climatic conditions.

[Physical development and teeth age of children aged 7-10 years]. / Rozwój fizyczny a wiek zebowy dzieci w wieku 7-10 lat.

The reported stomatological and paediatric examinations were carried out in 876 children aged 7-10 years. In the studied material accelerated eruption of permanent teeth coexisted with excessive body mass or height, and delayed eruption was related to below normal body mass and height.
