The aims of this study were to evaluate the radiopacity, compressive strength, setting time, and porosity of white Portland cement (PC) with the addition of bismuth oxide (Bi2O3), zirconium dioxide (ZrO2), and ytterbium trifluoride (YbF3) after immersion at 37 °C for 7 days in distilled water or phosphate buffer saline. Specimens measuring 8 mm in diameter(More)
INTRODUCTION Antioxidants protect against reactive oxygen species and expose beneficial anti-inflammatory activity when in contact with biological tissues. Dental materials that are used as temporary luting on fixed dental restorations are often in contact with injured gingival tissue, hence they should contain anti-inflammatory characteristics that are(More)
BACKGROUND/AIM The radiopacity of an endodontic material can considerably vary as measured on film and a digital sensor. Digital radiography offers numerous advantages over conventional film-based radiography in dental clinical practice regarding both diagnostic capabilities and postintervention procedures. The aim of this study was to investigate the(More)
This article presents a literature review on the resin bond to zirconia ceramic. Modern esthetic dentistry has highly recognized zirconia, among other ceramic materials. Biocompatibility of zirconia, chemical and dimensional stability, excellent mechanical properties, all together could guarantee optimal therapeutical results in complex prosthodontic(More)
This study examined the potential of a new porous calcium hydroxyapatite scaffold covered with poly (lactide-co-glycolide) (PLGA) as a bone substitute, identifying its advantages over Geistlich Bio-Oss®, considered the gold standard, in in vivo biofunctionality investigations. Structural and morphological properties of the new scaffold were analyzed by(More)
Calcium silicate cements (CSC) present numerous properties that favor its use in dentistry. The purpose of this study was to investigate how the addition of soy extract affects porosity and wettability of the CSC. Soy was added to commercially available CSC named Portland cement (Italcementi, Spa Bergamo, Italy) at 10 weight % Pure Portland cement was used(More)
The objective of this study was to elucidate micromechanical properties of Biodentine and two experimental calcium silicate cements (CSCs) using Reference Point Indentation (RPI). Biomechanical characteristics of the cement type and the effects of a radiopacifier, liquid components, acid etching treatment and bioactivation in simulated body fluid (SBF) were(More)
OBJECTIVE According to the ISO, the radiopacity of luting cements should be equal to or greater than that of aluminum. The aim of this in vitro study was to determine the radiopacity of 13 commercially available dental luting cements and compare them with human enamel and dentin. METHOD AND MATERIALS Five classes of luting cements were evaluated: zinc(More)
This study evaluated the radiopacity of seven commercial root canal posts. Digital radiographs of the seven commercial posts and of the same commercial posts and four artificial aluminum posts inserted in lower canines were obtained with a CCD-based digital sensor. The radiopacity of the posts was expressed as mm aluminum/mm material (mmAl). Subsequently,(More)
