OBJECTIVES This study evaluated the effects of the resin thickness on the microhardness and optical properties of bulk-fill resin composites. METHODS Four bulk-fill (Venus Bulk Fill, Heraeus Kulzer; SDR, Dentsply Caulk; Tetric N-Ceram Bulk Fill, Ivoclar vivadent; SonicFill, Kerr) and two regular resin composites (Charisma flow, Heraeus Kulzer; Tetric N-Ceram, Ivoclar vivadent) were used. Sixt...

Clay soils can exhibit swelling and settlement behaviour when interacted with water. The clays located in road infrastructure damage the pavement cause cracks because of and/or clays. freezing-thawing processes clay increase damages pavement. Additionally, strength losses occur. Weak be improved using various soil improvement techniques or without additives. In this study, liquid polymers (poly...

A colour ink jet printing with improved water fastness property was produced by using of special component in the ink’s formulation. In this study, the water fastness of ink jet prints which used acrylic/nano-silver resin nano-composite ink instead of conventional resin in ink’s formulation was examined. The nano composite resin was prepared via miniemulsion polymerization of acrylate monomers ...

PURPOSE To evaluate in vitro the fracture resistance of quartz fiber posts for three different dowel lengths. METHODS 30 single-rooted human premolars with similar root length and diameter were endodontically treated and randomly divided into three experimental groups (n = 10) according to the post space depth created: (1) 5 mm; (2) 7 mm; (3) 9 mm. Quartz fiber posts (Endo Light post) were ce...

Background: Teeth have an important role in a person, the most common cause of tooth loss is caries and periodontal disease. Tooth can be overcome by making dentures, removable denture components consist dental elements, clasps, bases. The base part that rests on soft tissues oral cavity where elements are attached. One mechanical properties for bases flexural strength. Acrylic resin material h...

OBJECTIVE To study the in vitro color changes of three dental resin veneering materials when immersed in tea, coffee and tamarind extracts. MATERIALS AND METHODS The color changes of heat polymerized tooth colored acrylic resin (Stellondetrey, B, F14, DPI Dental products of India Ltd, Mumbai), auto polymerized tooth colored acrylic resin (DPI, B, QV5, DPI Dental products of India Ltd, Mumbai)...

High accuracy dental impression is usually a first step during fabrication of indirect restorations that have to be seated in or on prepared teeth. The dimensional stability of the impression material could have an influence on the accuracy of the final restoration. Elastomeric materials (additioncured silicones and condensationcured silicones) are most frequently used as the impression materia...

OBJECTIVE We examined the influence of light intensity on surface free energy characteristics and dentin bond strength of dual-cure direct core build-up resin systems. METHODS Two commercially available dual-cure direct core build-up resin systems, Clearfil DC Core Automix with Clearfil Bond SE One and UniFil Core EM with Self-Etching Bond, were studied. Bovine mandibular incisors were mounte...
