Objective: To define the risk of development of periodontal diseases at vitamin D-resistant rickets. The material for the study was based on the data from 13 children of 0-18 years with vitamin D-resistant rickets (I group), 68 children with vitamin D-dependent rickets (II group), and the control group included 61 children of the same ages. The patients were divided into 3 age groups: I group of 0-5 years (deciduous/milk teeth occlusion), II group of 6-12 of years (mixed bite), III group of 13-18 years (permanent occlusion). For the qualitative data the differences between the groups were detected by using F criteria but for the quantitative data the differences between the groups were detected by Student's t test for independent selection. Mathematical processing was performed using statistical software SPSS-22. In all three groups the gingivitis of mild and moderate forms were fixed, among them acute course was revealed only in the group of vitamin D-resistant rickets. The rate of chronic, local, catarrhal and generalized gingivitis in the group of vitamin D-resistant rickets was reliably higher in comparison with both vitamin D-dependant rickets and control groups. In addition, a mild form of periodontitis with chronic course was revealed in all three groups the rate of which was reliably higher in the group of vitamin D-resistant rickets comparing with the ones of vitamin D-dependant rickets and control groups., Conclusion: the rate of inflammatory periodontal diseases in children with vitamin D-resistant rickets is higher than in children with vitamin D-dependent rickets and the control groups.

The aim of the study was to define interrelations between complications after veneer treatment with initial parameters of an oral cavity, state of an organism, social and biological factors. 65 patients with veneers treated between 2005 and 2009 at Margvelashvili Dental Clinic (Tbilisi) were investigated. Correlation analysis on Spearmen was spent with application of the package statistical programs SPSS 11.5. Chip of veneers finds out significant positive correlation with the following factors: a crossbite - r=0.2543, p<0.0409; decompensative caries - r=0.3189, p<0.0096; exhibiting of a pathological microflora - r=0.2879, p<0.0163; discoloration - patient with age 41-60 y. - r=0.3877, p<0.0014; focal infection contamination - r=0.2599, p<0.0366; often use of coffee - r=0.2819, p<0.0229; ulitis up to veneer - r=0.2444, p<0.0498; appearance line of demarcation - with the mechanical factor - r=0.3479, p<0.0045; use of synthetic fluids, - r=0.3823, p<0.0017; recurrence caries - with gastro-intestinal pathologies r=0.2924, p<0.0181; of a focal infection contamination - r=0.2756, p<0.0263; by feeding priority by carbohydrates - r=0.2324, p<0.0625; decompensate caries - r=0.2583, p<0.0377; Exhibiting of a pathological microflora - among males - r=0.2772, p<0.0254; by smoking - r=0.3227, p<0.0087; gastro-intestinal pathologies - r=0.2365, p<0.0579; by endocrine diseases - r=0.2546, p<0.0407; by focal infection contamination - r=0.5416, p<0.0000; decompensate caries - r= 0.2530, p<0.0420; by an ulitis - r=0.4551, p<0.0001; by a hygienic index - r=0.4611; p<0.0001; periodontal index - r=0.4611, p<0.0001; PMA index - r=0.3529, p<0.0039. The correlation circuit of the factors of complications after veneers will help the practical stomatologists with realization of purposeful prophylaxis.

The purpose of the research is to study local immunology of mouth cavity at complete prostheses with acrylic and polypropylene bases. Immunological parameters of saliva (sIgA, IgG and IgE), lysozyme activity at complete prostheses of teeth with acrylic and polypropylene bases in 40 patients from 45 to 75 were investigated. Lysozyme activity of mixed saliva was defined by turbidimetric method, concentration sIgA, IgG, and IgE - by method Mancini. The statistical data processing included calculation of average arithmetic sizes (X) and standard deviation. The authentic distinctions in immune parameters between groups were calculated (Student's coefficient). The analysis of the data was carried out with the help of a package of the applied programs SPSS 11.5. The comparative analysis immune of parameters of a saliva after complete prostheses with acrylic and polypropylene bases has shown that in a case acrylic of basis in comparison with polypropylene base, parameters IgA and lysozyme activity there are less, is higher IgG and IgE and factor immune of equation. Thus, after prostheses with acrylic of basis it is marked immunological shifts that can be infringement allergy by action acrylic base.
