Poly(methyl methacrylate) (PMMA), widely used in dentistry, is unfortunately a suitable substrate for Candida (C.) albicans colonization and biofilm formation. The key step formation C. ability to transit from yeast hypha (filamentation). Since oleic acid (OA), natural compound, prevents filamentation, we modified PMMA with OA aiming the antifungal PMMA_OA materials. Physico-chemical properties of novel composites obtained by incorporation 3%, 6%, 9%, 12% into were characterized...

<b><i>Objective:</i></b> A widely used chemical-mechanical method of gingival retraction can cause tissue damage. The aim this study was to test the influence procedures on bleeding index (GBI) and salivary concentration monocyte chemoattractant protein 1 (MCP-1) as an indicator inflammatory changes in gingiva. <b><i>Materials Methods:</i></b> effects 2 different agents (aluminum chloride ferric sulfate) were compared, particularly their...

Tooth preparation for a metal-ceramic crown with subgingival finish line can lead to inflammatory changes in the gingival tissue, often accompanied by cell damage. This study aimed evaluate clinical signs of inflammation and cytomorphological status tissue before after tooth preparation. The research included homogeneous group 19 patients an indication upper canine Before treatment, bleeding indexes were determined, swabs taken, direct smears prepared on slides cytomorphometric analysis....

Acrylic restorations in the mouth are exposed to strong occlusal forces. Their mechanical properties depend on type and method of their polymerization. The aim this study is a comparative analysis (flexural strength modulus elasticity) acrylic materials before after post-polymerization treatments (water boiling, microwave irradiation water storage). included denture base resins, as well an acrylate for orthodontic appliances impregnated with aesthetic beads. Flexural strength, elasticity...

Acrylic materials are used daily for the production of mobile dental restorations and orthodontic appliances. The presence residual monomer, as a product incomplete polymerisation material, results in more porous structure which greatly reduces mechanical physical quality acrylic increases absorption liquids. aim this study was to examine water different types resin material. In it assumed that cold polymerized acrylates show greater potential absorbing fluid from environment relation hot...

Abstract Objective The aim of the study was to develop Serbian language version Orofacial Esthetic Scale questionnaire (OES SERB) and evaluate its psychometric properties. Methods included 226 subjects – 110 dental students 116 patients (the validation sample). answered all questions individually with help supervisors, whereas prosthodontic were interviewed by same trained dentist. reliability validity assessed. Results Internal consistency OES‐SERB considered satisfactory (Cronbach's alpha...

Background and Objectives: According to the modified Williams theory, shape of maxillary central incisor corresponds alveolar ridge (dental arch) face. Moreover, standards beauty suggest that center face an individual with a full set teeth should match mandibular dental arches. The purpose this study is conduct comparative cross-sectional on matching face, arch as well midfacial line arches in subjects complete dentition. Materials Methods: included 90 both sexes. line, i.e., incisors, was...

Background/Aim. The wearing of acrylic dentures is the cause inflammatory reaction oral mucosa. aim this study was to investigate response rat tissues subcutaneous and intramuscular implantation different samples, by histopathological analysis tissue. Methods. included two samples hard three soft resins (heat cold polymerized), that were subcutaneously intramuscularly implanted in rats tissues. Implantation tests designed test biological surrounding tissue tested materials after their...

<b><i>Objective:</i></b> To detect activities of salivary myeloperoxidase (MPO) and concentrations tumor necrosis factor (TNF)-α as indicators inflammatory reaction immunoglobulin E an indicator allergic after complete insertion acrylic dentures. <b><i>Subjects Methods:</i></b> Complete dentures were made for a uniform group elderly patients, saliva samples taken immediately before they given to the well 2, 3, 7, 30 days dentures, with...

Introduction. Root canal preparation is one of the most important active phases in treatment infected and noninfected teeth. Nickel-titanium (NiTi) instruments are increasingly used endodontic therapy due to their superior properties compared those made stainless steel.
