Objective: Probable effect of fluoride containing materials like APF on sealants is very important. The purpose of this study is to assess the effect of frequent application of APF (1.23%) on the surface microhardness of two fissure sealants and one flowable composite.   Methods: In this experimental study, 81 specimens of two fissure sealants and one flowable composite were prepared, using s...

Introduction: This study evaluated microleakage of flowable and conventional composite in primary molar class II restorations using self-etch and total-etch bonding agents. Methods: Class II standard cavities were prepared on proximal surface of 48 primary molars. These cavities were restored using GrandioFlow and Grandio composites and Futurabond DC and Solobo...

Physical properties such as surface hardness of dental materials are directly linked to their clinical behavior. The aim of this study was to investigate the influence of extended curing time on the polymerization depth offluoride-containing materials used as pit and fissure sealants. Conventional and extended exposure times (20 and 60 seconds) were used to photoactivate a gold-standard pit and...

The degree of conversion (DC) and the released bisphenol A diglycidyl ether dimethacrylate (BisGMA), triethylene glycol dimethacrylate (TEGDMA) and urethane dimethacrylate (UDMA) monomers of bulk-fill composites compared to that of conventional flowable ones were assessed using micro-Raman spectroscopy and high performance liquid chromatography (HPLC). Four millimeter-thick samples were prepare...

OBJECTIVE The aim of this study is to evaluate if the cytotoxic effects of the Surefil SDR flow, bulk fill flowable composite resin and three conventional flowable materials (Venus Diamond Flow, Filtex Supreme XTE Flowable and Enamel plus HRi Flow) correlated with the conversion degree (DC); hardness and depth of cure are also assessed. MATERIALS AND METHODS Disks of each materials--cured usi...

This paper reports the properties of two series of flowable self-compacting slurry (SCS). In Series 1, a limestone quarry by-product, fine crushed sand (FCS), and ponded-CCPs were used. For Series 2, standard concrete sand and ponded-CCPs were used. For Series 1, five mixtures and for Series 2, six mixtures of flowable SCS were made. Ponded-CCPs and limestone quarry FCS content of the mixtures ...

PURPOSE The purpose of this study was to evaluate and compare the effects of different surface pretreatment techniques on the surface roughness and shear bond strength of a new self-adhering flowable composite resin for use with lithium disilicate-reinforced CAD/CAM ceramic material. MATERIALS AND METHODS A total of one hundred thirty lithium disilicate CAD/CAM ceramic plates with dimensions ...

This research was conducted to develop flowable slurry containing fibrous residuals from pulp and paper mills. Two types of flowable slurry containing ASTM Class C fly ash were produced: fly ash slurry and sandy slurry. Often, the fly ash slurry made without fibrous residuals showed a tendency to set rapidly, and become unworkable. When the cement-to-fly ash ratio was increased to extend the ti...
