Dişlerde çeşitli nedenlerle meydana gelen madde kayıpları direk ve indirekt uygulamalarla restore edilebilmektedir. Bu olgu sunumunda, beş ayrı vaka üzerinde, geniş diş dokusu kaybının olduğu posterior bölge dişlerinin kompozit restorasyonlarla (GC Gradia Plus, Tokyo, Japonya) tedavisi anlatılmaktadır. Aşırı kayıplı dişlerin konservatif hekimliği yöntemleri ile kalan korunarak preparasyonları y...

PURPOSE The aim was to assess monomer conversion, dimensional stability, flexural strength / modulus, surface apatite precipitation and wear of mono / tri calcium phosphate (CaP) and polylysine (PLS)-containing dental composites. These were formulated using a new, high molecular weight, fluid monomer phase that requires no polymerisation activator. MATERIALS AND METHODS Urethane and Polypropy...

tooth fracture is a common dental problem. by extension of cavity dimensions, the remaining tooth structure weakens and occlusal forces may cause tooth fracture. the aim of this study was to evaluate and compare the fracture resistance of teeth restored with direct and indirect composite restorations.sixty-five sound maxillary premolar teeth were chosen and randomly divided into five groups eac...

Objective:
 To compare and characterise commercial control composites. By characterising these composites, target properties for new experimental dental composites can be outlined.
 Materials Methods:
 Three commercial, two were compared investigated. The composition of materials provided from published literature manufacturer’s information. changes in intensity spectral peaks th...

DNA mismatch repair (MMR) is one of the most widely conserved DNA repair systems, which repairs mismatched bases generated mainly by the error of DNA polymerases during replication (Friedberg, et al., 2006, Iyer, et al., 2006, Kunkel, et al., 2005, Morita, et al., 2010). MMR increases the replication fidelity by 20 to 400-fold (Schaaper, 1993). Mutations and epigenetic silencing in MMR genes ca...

objectives : the aim of this study was to assess the effect of artificial accelerated aging (aaa) on color change of direct and indirect fiber-reinforced composite (frc) restorations. materials and methods: direct (z250) and indirect (gradia) composite resins were reinforced with glass (gf) and polyethylene fibers (pf) based on the manufacturers’ instructions. forty samples were fabricated and ...

This study tested and compared properties of six modern indirect veneering resin composites (VRC), namely Ceramage (Shofu), dialog Vario (Schütz Dental), Gradia Plus (GC Europe), in:joy (Dentsply), Signum composite (Heraeus Kulzer), SR Nexco (Ivoclar Vivadent). Specimens were fabricated from dentin enamel pastes following analyzed: (1) two-body wear (TB), (2) surface roughness (SR), (3) Martens...

To investigate the degree of conversion (DC), Martens hardness (HM), elastic indentation modulus (EIT), and flexural strength (FS) veneering resin composites (SR Nexco Paste (NP), Ceramage Incisal (CI), Gradia Plus (GP); n=60/group) cured with different polymerization devices (bre.Lux Power Unit, Labolight DUO, Otoflash G171, LC-3DPrint Box, PCU LED; n=12/subgroup) after storage. G171 DUO showe...

statement of the problem: optical properties of the composite resins, concerning their translucency and thickness, are affected by discolored tooth structure or inherent darkness of the oral cavity. purpose: this study aimed to compare the translucency parameter (tp) of five different composite resins in different thicknesses and to evaluate their masking ability in black backgrounds. materials...
