OBJECTIVES The aim of the present study was to evaluate the effect of four different sandwich techniques on gingival microleakage of Class II direct composite resin restorations. MATERIALS AND METHODS Fifty sound human premolars were selected and randomly divided into five groups (n=10). Class II box only cavities were prepared in one of the proximal(More)
AIM The purpose of this study was to assess the effect of different surface treatments on the shear bond strength (SBS) of a resin modified glass ionomer cement (RMGIC) to dentin. METHODS AND MATERIALS Forty human third molar teeth were randomly divided into four groups (n=10). The occlusal enamel was removed to obtain a flat surface of dentin. Each group(More)
AIM The purpose of the present randomized clinical trial was to evaluate the color change, rebound effect and sensitivity of at-home bleaching with 15% carbamide peroxide and power bleaching using 38% hydrogen peroxide. MATERIALS AND METHODS For bleaching techniques, 20 subjects were randomized in a split mouth design (at-home and power bleaching): In(More)
AIM The aim of this study was to investigate the fracture resistance and failure mode of premolars restored with composite resin using various prefabricated posts. METHODS AND MATERIALS Sixty sound maxillary premolars were divided into four equal sized groups. All but the control group received endodontic treatment followed by placement of(More)
OBJECTIVES To evaluate the effect of amalgam corrosion products in non-discolored dentin on the bond strength of replaced composite resin. MATERIALS AND METHODS One hundred and sixty-one Class I cavities were prepared on extracted premolars and divided into seven groups. Group 1: Light-cured composite; Groups 2, 3, and 4: Amalgam stored in 37°C normal(More)
Introduction: The aim of the present study was to evaluate the effect of glass ceramic insert in the sandwich technique to reduce microleakage in class II composite resin restorations. Methods: Sixty sound human upper second premolars were selected and randomly divided into six groups (n=10). Class II boxonly cavities were prepared in distal aspects of each(More)
OBJECTIVES This double-blind randomized placebo-controlled clinical trial evaluated the ability of a desensitizing agent and a self-etch adhesive on cervical dentin sensitivity (CDS) after periodontal surgery. MATERIALS AND METHODS Ninety hypersensitive teeth of 13 subjects were included in the study. After periodontal surgery, the teeth of each posterior(More)
OBJECTIVES Psychoactive drugs are responsible for pathological changes in the mouth including dental caries, which most troublesome. The aim of the present study was to evaluate the effect of heroin on several salivary factors which are involved in the oral health and their changes after methadone maintenance therapy (MMT). MATERIALS AND METHODS Forty(More)
BACKGROUND Based on the frequent application of composite resins as tooth-colored fillings, this method is considered a viable alternative to dental amalgam. However, this method has the low bond strength of the composite to dentin. To solve this issue, various dental adhesive systems with different characteristics have been developed by dentistry experts.(More)
OBJECTIVES Evaluation of postoperative sensitivity in posterior teeth restored with etchand- rinse adhesive and composite resin after application of 2% chlorhexidine solution. METHOD AND MATERIALS Thirty participants with similar dental caries on both sides of the jaws were selected. After cavity preparation, each tooth was randomized to one of the(More)
