USE OF FIBRE MATRIX FOR PRESERVATION OF THE ALVEOLAR CREST'S GEOMETRIC PARAMETERS AFTER TOOTH EXTRACTION.

The objective of the research consisted in the evaluation of the possibility and effectiveness of fibre matrix use in order to maintain the original geometric parameters of the osseous crest in the places of alveolar sockets of the extracted teeth. Patients in the study group underwent filling of a post-extraction alveolar socket by fibre matrix, developed by the authors of the article, with further overlapping with a polymeric membrane (KLS Martin), which was modified in each certain case according to the peculiarities of defect configuration by means of thermoactive pressing method (Patent for invention of Ukraine №114143). Filling or overlapping of the post-extraction alveolar sockets were not performed in patients of the control group.

Two novel mutations in mitochondrial acetoacetyl-CoA thiolase deficiency.

We report a new patient with acetoacetyl-CoA thiolase deficiency in whom we found two new missense mutations.

[Genetic mental retardation in the district of Banská Bystrica].

The authors investigated the prevalence of mental retardation (MR) in 6-14-year-old children in the district of Banská Bystrica. The aim was to assess the prevalence of MR and the ratio and character of genetic factors participation in its genesis. The group was based on the Uniform records of defective children and health records of children from special schools and social care institutes in 1987.
