Background: In addition to tooth decay, that is the most common disease of hard dental tissues, the dentist often encounters with so-called noncarious lesions. The etiopathogenetic factors of these defects, if not removed, are a frequent cause of conservative therapy failure and should be taken into account during treatment. In the long run, it is not enough just to repair the defect by filling. In case of persistent causes, there is a high risk of re-failure of the reconstruction therapy and recurrence of the problem. The paper summarizes the current knowledge of the clinical manifestations of individual types of noncarious defects, their etiopathogenetic...

Background: Ceramics is a mixture of one or more metallic components with a non-metallic element, usually oxygen. The result is a chemically and biochemically stable substance that is hard, firm, brittle and thermally and electrically non-conductive. These properties are used in dentistry to produce dental ceramic restorations [14]. From all-ceramic or metalloceramic crowns and bridges, inlays, onlays, veneers and implants and their abutments, and teeth intended to use with the removable dentures [15].Dental ceramics consist of a combination of amorphous glass (binder) and ceramic crystals (filler), whose relative ratio determines the final...

Wear of Dental Filling Materials and Possibilities of its Measurement

Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2018; 118(4): 95-103 | DOI: 10.51479/cspzl.2018.013  

Background: Tooth wear is a complex multifactorial phenomenon conditioned by the interaction of biological, mechanical, chemical and tribological factors. The surface of hard dental tissues as filling material replacing enamel and dentine has mechanical load by antagonist (attrition) or another object in the oral cavity such toothbrush, toothpaste, etc. (abrasion). These processes lead to surface defects of hard dental tissues and fillings. The report describes the possible methods of experimental ("pin on disc" method, tooth brushing machine, computer-controlled jaw simulator, material hardness and elastic modulus measurement using nanoindentation,...

Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2018; 118(4): 84-89 | DOI: 10.51479/cspzl.2018.011  

Introduction and aim: Nonendodontic lesions can be misdiagnosed as pathoses of endodontic origin. One of the most common nonodontogenic lesions of the oral cavity is the nasopalatine duct cyst, which is difficult to distinguish from periapical lesion. The aim of this case report is to familiarize readers with differential diagnosis of this disease. Case report: The patient who had suffered lateral luxation of tooth 11 aproximately 25 years ago presents with palatal abscess of premaxila. After non surgical retreatment of tooth 11 the symptoms disappeared, but the tooth become symptomatic two years after. After CBCT scan was taken the...
