ODONTOGENIC KERATOCYSTS TREATMENT - OUR EXPERIENCE

Fabián J., Pazdera J., Kolář Z.

Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2021; 121(2): 35-40 | DOI: 10.51479/cspzl.2021.005  

Introduction: Odontogenic keratocystics are benign intraosseous lesions. They are characterised by an local aggresive behaviour. Expansion is in anterior-posterior direction. This lesions were hidden for a  long time. Orthopantomogram is gold standard examination, so nowadays diagnostics is not so difficult. But still there is relatively high recurrence rate and the choice of operation method is not definite. In this retrospective study is presented treatment modalities and succes rate.Methods: In this retrospective study 62 patients are presented. This lesions were treated from 2000 to 2019 on Department of Oral and Maxillofacial Surgery in...

BIOCERAMIC-BASED ROOT CANAL SEALERS - USE IN ENDODONTICS

Somolová L., Zapletalová Z., Rosa M., Harvan Ľ., Voborná I., Morozova Y.

Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2021; 121(2): 41-47 | DOI: 10.51479/cspzl.2021.006  

Introduction and aim: Calcium silicate-based sealers, also referred to as bioceramic-based sealers, can, thanks to their properties, ensure hermetic sealing of root canals in endodontics. The recommended single-cone hydraulic cold obturation method or possibly the method of cold lateral condensation of gutta-percha seems to be a suitable way of using this type of sealers in endodontic obturation. With the correct selection of the main gutta-percha cone, which corresponds exactly to the apical dimension after the root canal has been instrumented, reliable sealing can be achieved in conjunction with a sealer applied as a filler. Due to the high...

DENTAL COMPOSITE FILLING MATERIALS AS A POTENTIAL RISK OF TOXICITY FOR HUMAN ORGANISM

Tkáčiková S., Sabo J.

Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2021; 121(2): 48-54 | DOI: 10.51479/cspzl.2021.007  

Introduction, aim: Composite materials used in dentistry are increasingly used for several reasons - aesthetics, hypersensitivity of some individuals to amalgam and concerns about the possible release of amalgam metals, and at the same time limiting its use due to the negative impact on the environment both during production and disposal. Composite materials consist of monomers, filler, polymerization initiation system and other substances that improve the properties of the filler. After application to the cavity, the filler material solidifies by a polymerization process which is initiated chemically, by light or dual. The conversion of monomers...

SUMMARY OF KNOWLEDGE ABOUT 3D PRINTING AND ITS USE IN DENTISTRY

Savková N., Harvan Ľ., Jusku A., Saygili S., Jezdinská K., Hulvert J.

Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2021; 121(2): 55-64 | DOI: 10.51479/cspzl.2021.008  

Introduction, aim: The rise of research papers and investments made into 3D printing are the proof of the increased interest about this manufacturing method. The American Charles W. Hull is considered to be the inventor with the first patent in the field. The principle of 3D printing is printing the desired item in layers according to its template, most often present in .stl format. There are seven main technological processes of 3D printing, five of them are used in dentistry. Text deals with the three methods that are used the most: Vat Polymerisation, Material Extrusion and Powder Bed Fusion. In dentistry, additive manufacturing already has...
