Objective: The purpose of this study was to evaluate the effects of application of three over the counter whitening toothpastes (Colgate Optic White, Aquafresh Ultimate White and Crest 3D White) on the color stability of different esthetic restorative materials (Resin composite/Filtek Z250 XT, resin modified glass ionomer/GC Fuji II LC, and glass ionomer/Ketac Molar Quick Aplicapweek) commonly ...

UNLABELLED Secondary caries is still the main cause of restoration replacement, especially on the root surface. OBJECTIVE This in vitro study evaluated the cariostatic effects of fluoride-containing restorative materials associated with fluoride gels, on root dentin. MATERIALS AND METHODS A randomized complete block design was used to test the effects of the restorative systems, fluoride re...

objective: this study investigated the antibacterial properties of an ion-releasing resin composite (degufill), a hybrid resin composite (inten-s), a compomer (compoglass f) and a resin-modified glass ionomer (vitremer) against streptococcus mutans. materials and methods: the bacteria were derived from the dental plaque and cultured on blood agar plates. eppendorf tubes were filled by unset res...

Background & Aims: Secondary caries is one of the most common problems in restorative dentistry. The release of flouride ions could substantially benefit the tooth enamel and neigboring dentin because flourid can combat caries. The purpose of this in vitro study was to evaluate the solubility rate and release of fluoride from tooth-colored restorative materials (Iono CID, Fuji II LC, FugiIX, Fu...

OBJECTIVES Aluminum step wedge (ASW) equivalent radiodensity (eRD) has been used to quantify restorative material's radiodensity. The aim of this study was to evaluate the effects of image acquisition control (IAC) of a digital X-ray system on the radiodensity quantification under different exposure time settings. MATERIALS AND METHODS Three 1-mm thick restorative material samples with variou...

AIMS The aim of the present study is to compare and assess the fracture resistance of root canal treated teeth with different restorative materials. MATERIALS AND METHODS The present in vitro study was carried out on seventy-five freshly extracted, noncarious, single-canal human lower-first premolars with similar anatomic characteristics. Teeth were randomly assigned to five groups with 15 te...

OBJECTIVES The purpose of this study was to investigate the effect of different air-polishing powders on the color stability of different types of composite resin restorative materials. MATERIAL AND METHODS Thirty cylindrical specimens (15×2 mm) were prepared for each of 7 composite resin restorative materials. All specimens were polished with a series of aluminum oxide polishing discs (Sof-L...
