Svoboda P., Šikula P., Vrbka M., Nečas D., Roubalíková L.

Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2021; 121(4): 108-115 | DOI: 10.51479/cspzl.2021.012  

Introduction and aim: Tribological methods are widely used not only in the field of technical sciences, but increasingly also in the field of human and veterinary medicine. Monitoring the wear of biological and prosthetic materials is now a common part of test protocols for joint replacements. From this point of view, the use of tribology in dentistry is a logical step in the development and stress monitoring of a number of materials used in restorative and prosthetic dentistry, but also in the field of dental hygiene in cleaning, including depuration techniques.Results: The creation of appropriate conditions for the simulation of contact in...

Introduction: Obstructive sleep apnoea (OSA) is considered to be a serious condition associated with daytime sleepiness which leads to cognitive impairment, hypertension, cardiovascular diseases and diabetes mellitus. OSA is a sleep disorder with multifactorial etiology characterised by recurrent episodes of partial or complete obstruction of upper airways during sleep, leading to a decrease in blood oxygen saturation level to 70%.Presentation: The prevalence of OSA is high in adult patients in developed countries. Orthodontists often look after patients with OSA, whose craniofacial and dental anomalies, biotype of the facial skeleton and specific...

Introduction: In modern endodontics, there is a constant development of new procedures and requirements for high-quality and reliable materials to fill the root canal system are rising. A few years ago, a new types of calcium silicate-based root canal sealers were launched on the market, which could meet most of the parameters of a perfect sealing material. Newer generations of these sealers contain calcium phosphate and are also referred to in the literature worldwide as bioceramic sealers. Aim of the article: The aim of this article is to present the characteristics of this group of sealers and to outline their chemical, physical and biological properties....
