Binary Titanium-tantalum alloys and their Biocompatibility
S. Bartáková, P. Prachár, J. Kudrman, B. Podhorná, P. Černochová, V. Březina
Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2009; 109(3): 37-40
The paper deals with investigation of biological properties of binary alloys of titanium with tantalum in relation to the ratio of mass share of tantalum in the alloy. Tests of cytocompatibility and genotoxicity have been made. The tests of cytocompatibility included those of cell growth, cell adherence, dilation test, tolerance test in monolayer, and in suspension. The genotoxicity tests encompassed those of induction of atypical mitoses, induction of chromosomal aberrations in a cell line and in human peripheral lymphocytes. Based of the evaluation of these biological tests the authors determined suitability of using such alloys in oral implantology....
Tooth Autotransplantation. A Review
P. Černochová
Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2009; 109(3): 41-48
Objective: The present articles reviewed literature deals with tooth autotransplantation as far as the successfulness is concerned. Material and methods: The authors searched internet databases (Medline, EBM, Embase, Web of Science, Lilacs) with the assistance of a professional librarian. The search was supplemented with the author's in the PubMed database in the lists of used literature of the available full texts of papers dealing with the evaluation of successfulness of tooth autotransplantation. The detailed analysis selected articles fulfilling entry criteria - tooth autotransplantation in human subjects, well described methodology...
Salivary Markers for Diseases of Periodontium and other Organs

The determination of biomarkers in saliva has become an important part of laboratory diagnostics and prediction of diseases concerning periodontium as well as other organs. Salivary biomarkers (e.g. enzymes, protein markers or markers of oxidative stress) may serve for the determination of activity as well as prognosis of periodontium diseases.Saliva also contains a series of markers which make it possible top predict the risk of some general diseases (e.g. diabetes mellitus, cardiovascular, oncological, endocrinological or psychiatric diseases).The proteomic study of salivary components makes it clear that there is an association between periodontium...
Biophysical Mechanism Determining Dental Implants Biocompatibility and Conditioning their Osseointegration
S. Bartáková, P. Prachár, S. Hasoň, R. Silvennoinen, L. Cvrček, L. Strašák, L. Fojt, A. Avranas, V. Vetterl

Adsorption of biopolymers at the titanium and titanium carbide surface increases the optical roughness as well as the thickness and refractive index of the surface layer. Fibrinogen is better adsorbed at the titanium surface which is treated by polishing and etching than at the surface treated only by polishing. The best adsorption of fibrinogen was observed at the titanium carbide surface prepared by plasma-enhanced chemical vapour deposition, the optimal ratio was Ti0,38 - C0,62 a Ti0,09 - C0,91. The surface of dental implants treated by this way should speed up their osseointegration and healing. The single...
Healing of Pathologic Bone Cavities of Jaws after Augmentation
M. Machálka, O. Bulik, O. Liberda
Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2009; 109(3): 54-57
Pathologic bone cavities of jaws are related to occurrence of bone cysts and tumors. In an extensive bone cavity after cystectomy, the post-operative haematoma may disintegrate due to inflammation at the dehiscence of the mucosa suture. The cavity originated by the cyst is connected with the oral cavity; the healing is complicated and long-continuing. We endeavor to fill this cavity with some kind of material that would not only reduce the cavity extent but also stimulate the bone re-creation.Within the framework of our research activity, we applied three shares of human lyophilized bone mash and one share of tricalcium-phosphate, which were mixed...
Effect of the Implant Length on its Primary Stability
L. Dzan, L. Čapek
Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2009; 109(3): 58-62
Dental implantology is one of the fastest developing areas of stomatology. An implantologists needs to have good quality medically proven information so that they can provide the best care for the patience from what today's science and market offers. Long term correct functioning of the implants is influenced by their design (size, surface, diameter and length) and surgical procedure of the implantation. The subject of this work is the evaluation of the influence of the length of the implant on its primary stability measured by Resonance Frequency Analysis (RFA) and a resulting set of parametric calculations with using the method of the sinite elements.
Case Report
Papillon-Lefevre Syndrome
L. Izakovičová Hollá, A. Fassmann, M. Kukletová, V. Sazmová
Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2009; 109(3): 31-36
Papillon-Lefevre syndrome (PLS) is a rare autosomal recessive disorder characterized by severe early-onset periodontal destruction involving both the deciduous and permanent dentition and skin lesions of palmoplantar hyperkeratosis. Recently it was found that PLS patients carry loss-of-function mutations in the gene encoding cathepsin C (CTSC). The aim of this study was analyzed the CTST gene in one Czech family with PLS. Peripheral blood samples were obtained from individuals belonging to this family for DNA isolation. Mutations were identified by direct sequencing of genomic DNA amplified for selected regions of the cathepsin C gene. 12-old year...
