Mice were orally inoculated with gram negative anaerobic bacteria Escherichia coli as a gold standard bacteria in research on systemic immune responses or periodontal pathogenic bacteria Porphyromonas gingivalis. The change in the level of nitric oxide was evaluated in kidneys, as a result of swallowing of bacteria.

COBISS.SI-ID: 3690106Under the supervision of prof. Petelin, Eva Skalerič determined the dental status and condition of periodontal tissues, periodontal treatment needs and risk factors affecting the progression of periodontal disease in the 10- to 20-year period, in the inhabitants of Ljubljana. It was determined examining 247 subjects aged 35 to 85 years that their dental status and condition of periodontal tissues has worsened comparing to their status 10 and 20 years ago, when they already were examined in epidemiological studies. The author has estimated the size of periodontal wound using an innovative approach. Active/bleeding wound around the teeth was defined in the subjects examined, demonstrating that inflammatory burden of periodontal disease is associated with the level of C-reactive protein in serum, which is an indicator of the systemic response of the organism. She also evaluated a new risk factor for periodontal disease, the gene polymorphism for IL-1. A combination of determination of gene polymorphisms of IL-1 with the already known risk factors would lead to an earlier diagnosis of periodontal disease and determining the person's susceptibility to the disease development.

COBISS.SI-ID: 266646784Background:Swallowing pattern is important in the aetiology of unilateral posterior crossbite (ULCB). The aim of this study was to assess the swallowing pattern and tongue function during swallowing in children with ULCB in deciduous dentition using B-mode and M-mode ultrasonography.Materials and methods:Twenty-three children with ULCB, aged 4.1-6.6 years, and 22 children without ULCB, 5.7-6.7 years, were examined with simultaneous B- and M-mode ultrasonography. The swallowing pattern was assessed according to the action of genioglossus muscle in ultrasound images with the scan line of the ultrasound transducer set through the tongue tip. The tongue movements (duration, range, and speed) were compared within each subphase (I, IIa, IIb, IIIa, and IIIb) and in the entire swallowing cycle between the children with ULCB and without ULCB.Results:The visceral swallowing pattern was found in 83 per cent of children with ULCB and in 36 per cent of children without ULCB; the difference was statistically significant. The duration of phase IIb and the entire swallowing act was found to be statistically significantly prolonged in the ULCB group. Furthermore, the range of the tongue movement in phases and in the entire swallowing act was statistically significantly larger in the ULCB group. The speed of the tongue movement was statistically significantly higher in the ULCB group in phase IIa.Conclusions:The 2D ultrasonography was used to evaluate the prevalent type of swallowing in children with ULCB. Visceral type of swallowing pattern and the changed tongue function during swallowing seem to be important factors in the aetiology of ULCB.
