The Effect of the Hand and the Power Driven Rott Canal Rinse

M. Jurisa, L. Roubalíková

Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2006; 106(5): 87-90  

The authors compare the effect of the various methods of the rinse of the root canal. 12 extracted single root teeth were randomly dividend into 3 groups. The endodontic treatment was performed using hand instruments under standard conditions (EDTA gel in combination with 2% NaOCl). In the first group only hand rinsing was preformed, in the second group the special endodontic canila was used ane in the third group the power driven instrument Rinse Endo, DürrDental, Germany) was used. After the preparation the teeth were split longitudinaly and microscopically observed. The clean areas were quantified and the groups were compared statistically with...

The Effect of Hand and Power Driven Root Canal

L. Gregor, L. Roubalíková

Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2006; 106(5): 91-97  

The authors compare the cleaning effect of various root canal preparation techniques (hand as well as power driven preparation). Two hand techniques (circumferential filing and balanced force technique) and two power driven techniques (the rotary system Wizard CD Plus, Medin, CR, and oscillating NiTi instruments AET Endo-EZE, Ultradent, USA) were used. The preparation was provided under standard conditions (lubrication with the EDTA gel, rinsing with 2% NaOCl). After the preparation the specimen were split longitudinaly and observed in SEM using the three step scala of the cleanliness of the root canal walls. Part of the specimen was split transversaly...

Perspectives of Advanced Molecular Methods for the Detection of Periodontal Pathogens

J. Janata, K. Hercík, G. Novotná, P. Branny, J. Dušková

Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2006; 106(5): 127-130  

The publication summarizes the present state in the diagnostic of periodontal pathogens. It discusses main advantages and pitfalls in classical cultivation methods and new DNA techniques. In the recent methods of molecular diagnostics the method of hybridization in situ is described in more detail. Its basis, various variant procedures and possibilities are explained including specific examples of the use the detection of periodontal pathogens.

Methods of Tooth Pulp Sampling for Isolation and Cultivation of Stem Cells

R. Ivančaková, T. Soukup, J. Suchánek, J. Karbanová

Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2006; 106(5): 131-135  

Mesenchymal stem cells (MSC) are capable of spontaneous generation of a whole spectrum of cells of mesenchymal origin. Moreover, they can converse even into elements of different embryonic stems. Such therapeutic potential may be expected only on human embryonic SC which, however, do not fulfill histocompatibility with the recipient tissues. Moreover, MSC may be isolated from relatively easily accessible source such as dental pulp, in contrast to such tissue specific SC as for example neural SC. When using the method of cultivation of SC isolated from human bone marrow we developed, SC were identified in the dental pulp tissue.Stem cells of dental...

Osteonecrosis of the Jaws in Treatment with Bisphosphonates

M. Machálka, Z. Adam, O. Bulik, M. Kozumplíková

Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2006; 106(5): 136-139  

Bisphosphonates are an integral part of the comprehensive treatment strategy in patients in whom either bone metastases arise or bone metabolism disorders occur in terms of osteoporosis. Basic principle of the effect of bisphosphonates consists in their selective trapping in the bones where they create a protective barrier against bone destruction. By reason of interference with the metabolism of triphosphates, bisphosphonates inhibit the bone cells, i.e. osteoclasts and also contain an important anti-angiogenic effect, which is desired against the oncogenous activity. After introducing the bisphosphonates into treatment, initially no effect on quality...

Resorption of Augmenting Materials Used in Sinus Lift Operation

T. Brázda, A. Šimůnek, D. Kopecká, R. V. Somanathan, J. Bukač

Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2006; 106(5): 140-143  

In certain cases conditions in oral cavity for introducing dental implants should be prepared before the operation. In lateral section of upper jaw the augmenting sinus lift procedure is almost an indispensable part of implantological therapy. The aim of this contribution was to verify resorption of augmentation materials used in the sinus lift operations. The group includes 50 patients, who underwent sinus lift procedure. In 20 patients we use ß-tricalcium phosphate (Cerasorb, Curasan Pharma), in 20 other patients the deproteinized bovine bone (Bio-Oss, Geistlich) and in 10 others an autogenous bone taken from tuber maxillae. Eighteen months after...

Aspergillomas of Maxillary Sinus

Z. Průdek

Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2006; 106(5): 144-148  

The variety of clinical findings, possible causes of the illness and its treatment described in this work refer to the patients of the Oral, Jaw and Face Surgery Ward of the hospital in Kyjov and cover a period of three years.

Preservation of Alveolar Ridge after Preimplantation Tooth Extraction (A Review)

R. Jurkovič, P. Stanko

Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2006; 106(5): 149-153  

The aim of the athors was to provide and represent different possibilities offered by materials for substitution of bones used after tooth extraction as a prevention of resorption of alveolar process. The use of autogenous bone, allogenic and xenogenic grafts, alloplastic and synthetic materials is described. Membranes used for controlled bone regeneration in the described indication are described. The aim of preserving the alveolar ridge is to preserve ideal anatomical conditions, which does not only provide the correct function, but also adequate aesthetic of prosthetic rehabilitation.
