The study has analysed situation in non-cooperative children admitted for dental treatment in 2004. The aim of the study was to evaluate the prevalence of dental caries in 6-19-year-old children (N = 78) treated under general anaesthesia (GA), and to compare the treatment plan based on a child patient's preliminary examination and the treatment need assessed during the respective therapy. The type of health insurance, reason for poor cooperation and referring facility were followed as well. Dental records of 78 children (mean age 11.5, SD 3.27) were used, the data were gathered and evaluated. The children were divided into 4 groups based on the diagnosis:...

This study examined the mechanical and biological properties of titanium alloy implant cores with a buffer layer from zirconia and a coating of hydroxyapatite created with pulsed laser deposition (PLD). The thickness of the zirconia layer was 50 - 100 nm and the hydroxyapatite layer ~600 nm. We measured crystallinity, morphology, wettability and Ca/P ratio of the hydroxyapatite layer. The methods used for physical evaluation were electron microscopy, X-ray diffraction, goniometric measurement of contact angle and wavelength dispersive X-ray analysis. The physical tests summarized good mechanical properties and a satisfactory adhesion to a titanium...

In some patients, a blue-grey stained areas (pigmentation) developed after a certain period of time in the area of tooth crown. The paper infers the mechanism of pigmentation development, which is based on corrosion processes of materials used in the tooth reconstruction. In order to determine the conditions to which metal materials are exposed in vivo, oxidation-reduction potentials and pH of saliva and sulcular fluid were measured. The pH of saliva was in the range of 4.8 - 7.8 and that of sulcular fluid was 6.3 - 7.8. The oxidation-reduction potentials reached the values of 0.109-0.432 V/SHE in saliva and 0.149-0.344 in sulcular fluid. The analysis...
Direct Applications of Fiber. Composites Substitution of Missing Frontal Teeth
L. Roubalíková, J. Vaněk, J. Jančář
Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2007; 107(1): 10-15
Introduction: The use of resin pre-impregnated fiber reinforced composite (dentapreg) materials in dentistry has been growing rapidly over the last 10 years in applications such as splinting, orthodontic retention as well as single tooth fixed partial dentures (FPD) and reinforcement of temporary as well as definitive bridges. Aim: The aim of this contribution was to evaluate whether adhesive bridges prepared using dentapreg frameworks can provide a functional, temporary prosthetic solution. Material and methods: The frameworks were formed using commercial grade pre-impregnated FRC strip (DentapregTM Bridge) adhesively...

Internal Granuloma - Present State of the Problem
J. Netolický, E. Záhlavová
Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2007; 107(1): 14-21
It has been generally acknowledged that internal granuloma (internal resorption, granuloma internum) originates on the basis of disorder of pulp metabolism, associated with degenerative processes, which follow to chronic inflammation of tooth pulp.The authors describe the present state of the problem in teeth with internal granuloma. In a long-term clinical study they document the occurrence of 25 internal granulomas. Their possible etiology is evaluated, the clinical course is described and present possibilities of treatment are discussed in particular.In suitable cases the authors employ repeated filling of the root canal with pure preparations...
The Causes of Origin and Present Possibility for Treatment of Alveolitis (A Review)
K. Chytilová
Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2007; 107(1): 22-26
The paper describes physiological course of the extraction wound healing, clinical picture and diagnostics of the alveoral bony socket inflammation. The authors also reports on the causes, present possibilities of therapy and prophylaxis of inflammatory complications in healing of the extraction wound.
