Optical properties of composite restorations influenced by dissimilar dentin restoratives
(Elsevier Sci Ltd, Oxford, 2018)
Objectives. To evaluate optical properties (color and translucency) of 'sandwich' restorations of resin-based composites and esthetically unfavorable dentin restoratives. Methods. Cylindrical 'dentin' specimens (8 mm in ...
Electrochemical monitoring of the breast milk quality
(Elsevier Sci Ltd, Oxford, 2018)
The electrochemical techniques were used to determine the total antioxidant capacity of breast milks and the results were compared with a commonly used spectrophotometric (2,2-diphenyl-1-picrylhydrazyl, DPPH) method. Breast ...
Human fetal osteoblast behavior on zirconia dental implants and zirconia disks with microstructured surfaces. An experimental in vitro study
(Wiley, Hoboken, 2016)
ObjectivesTo measure the lateral surface area of microgrooved zirconia implants, to evaluate the cell geometry and cell density of human fetal osteoblasts seeded on zirconia microgrooved implants, to describe the surface ...
Levels of oxidative stress biomarkers and bone resorption regulators in apical periodontitis lesions infected by Epstein-Barr virus
(Wiley, Hoboken, 2018)
AimTo investigate whether apical periodontitis lesions infected by Epstein-Barr virus (EBV) exhibit higher levels of oxidative stress biomarkers [8-hydroxydeoxyguanosine (8-OHdG) and oxidized glutathione (GSSG)] and bone ...
Bone loss biomarkers associated with peri-implantitis. A cross-sectional study
(Wiley, Hoboken, 2013)
Aim To investigate the levels of biomarkers associated with osteoclastogenesis in patients suffering peri-implantitis and to compare them with levels in healthy peri-implant sites and severe chronic periodontitis. Material ...
Investigations of corrosion on the surface of titanium substrate caused by combined alkaline and heat treatment
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
In this research, the structure changes along the depth gradient layers of titanium substrate, after etching with NaOH and subsequent thermal treatment at various temperatures between 300 and 800 degrees C, were investigated ...
Human Cytomegalovirus and Epstein-Barr Virus in Etiopathogenesis of Apical Periodontitis: A Systematic Review
(Elsevier Science Inc, New York, 2014)
Introduction: During the last decade, a hypothesis has been established that human cytomegalovirus (HCMV) and Epstein-Barr virus (EBV) may be implicated in the pathogenesis of apical periodontitis. The aim of this review ...
Dental Pulp Blood Flow and Its Oscillations in Women with Different Estrogen Status
(Elsevier Science Inc, New York, 2012)
Introduction: The skin microcirculation is significantly affected by serum estrogen levels. The objective of this study was to investigate the effects of estrogen serum level changes associated with the menstrual cycle and ...
Melatonin levels in human diabetic dental pulp tissue and its effects on dental pulp cells under hyperglycaemic conditions
(Wiley, Hoboken, 2018)
AimTo investigate melatonin (MEL) levels in human dental pulp tissue (hDP) in type 2 diabetic (T2D) participants and the underlying molecular mechanisms of its effects in human dental pulp cells (hDPCs) under hyperglycaemia. ...
Tissue Dissolution by Sodium Hypochlorite: Effect of Concentration, Temperature, Agitation, and Surfactant
(Elsevier Science Inc, New York, 2010)
Aim: Sodium hypochlorite is the most commonly used endodontic irrigant because of its antimicrobial and tissue-dissolving activity. The aim of this study was to evaluate and compare the effects of concentration, temperature, ...
