INTRODUCTION Preventive resin restorations (PRR) are the conservative choice for the most common carious lesions in children. Thus, new age flowable resin composites with higher filler content are readily used. The aim of this study was to evaluate the microshear bond strength and microleakage of two flowable resin composites containing different percentages of nano zinc oxide (NZnO) particles,...

OBJECTIVES The aim of this study was to evaluate the effect of three different drinks on the color parameters of four different restorative materials. MATERIALS AND METHODS Three different composites (Filtek Ultimate Universal Restorative, Filtek Ultimate Flowable, and Filtek Silorane, 3M ESPE) and a polyacid-modified composite resin material (Dyract XP, Dentsply DeTrey GmbH) were evaluated. ...

Purpose The aim of this in vitro study was to evaluate the color stability and degree of conversion (DC) of dual-cure and light-cure cements and flowable composites after thermal aging. Materials and Methods A total of 50 human incisors were prepared and divided into six groups (n = 10). Veneers were fabricated using IPS Empress Direct composite resin were bonded with three types of luting ag...

introduction :the aim of this study was to evaluate and compare the in vitro effect of the erbium-doped yttrium aluminum garnet (er:yag) laser with different radiation distances and high-speed rotary treatment on the shear bond strength of flowable composite to enamel of human permanent posterior teeth . methods : freshly extracted human molar teeth with no caries or other surface defects were ...

Aim. Study aimed to determine effects of flowable composites as liner on marginal and internal voids in MOD composite restorations with dif ferent gingival levels. Methods. 45 molars were prepared for MOD cavities. Finish line was prepared 1 mm apical to mesial, and 1 mm coronal to the cemento-enamel junction on distal. Teeth were restored with: Solitaire; Solitaire + Revolution; Surefil; Suref...

BACKGROUND Evaluation of microleakage is important for assessing the success of new restorative materials and methods. AIM AND OBJECTIVES Comparative evaluation of microleakage in Class II restorations using open vs. closed centripetal build-up techniques with different lining materials. MATERIALS AND METHODS Standardized mesi-occlusal (MO) and distoocclusal (DO) Class II tooth preparations...

STATEMENT OF PROBLEM Reattachment of the fractured tooth fragment should be considered as a conservative treatment and valid alternative to a composite restoration. PURPOSE This in vitro study was to evaluate the influence of different adhesives and composite resins on fracture resistance of dental fragment reattached to the sectioned incisal edges. MATERIALS AND METHOD 120 sound human maxi...

OBJECTIVE The aim of the study reported here was to evaluate the performance of a self-adhesive flowable composite and two self-etching adhesive systems, when subjected to cyclic loading, in preventing the nanoleakage of Class V restorations. METHODS Wedge-shape Class V cavities were prepared (4×2×2 mm [length × width × depth]) on the buccal surfaces of 90 sound human premolars. Cavities were...

Background and Aim: Changing the color of resin luting cements could affect the aesthetic appearance of thin porcelain veneer. The aim of this in vitro study was to evaluate the effect of artificially accelerated aging on color stability of light-cured resin cement and flowable composite as a luting agent through the porcelain veneer. Materials and Methods: This experimental study was carried ...
