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 ...
Cytotoxicity and genotoxicity of a low-shrinkage monomer and monoacylphosphine oxide photoinitiator: Comparative analyses of individual toxicity and combination effects in mixtures
(Elsevier Sci Ltd, Oxford, 2017)
Objective. To compare cytotoxicity and genotoxicity of novel urethane-based monomer FIT-852 and monoacylphosphine oxide photoinitiator (Lucirin TPO) with conventional Bisphenol A-glycidyl-methacrylate (BisGMA) and triethylene ...
Factors influencing risk of bleeding after dental extraction in hemophilia patients
(Wiley-Blackwell, Hoboken, 2015)
Paranasal sinus osteoma: is there any association with anatomical variations?
(Int Rhinologic Soc, Utrecht, 2013)
Background: Developmental disturbances of the paranasal sinuses are proposed as the cause of osteoma. We examined whether such disturbances may result in the frequent presence of anatomical variations of the paranasal ...
Expression and mutation analysis of heterogeneous nuclear ribonucleoprotein G in human oral cancer
(Elsevier Science Bv, Amsterdam, 2011)
We previously reported that wild type (wt) hnRNP G exhibited tumor suppressive activity in human oral squamous cell carcinoma (HOSCC) cell lines lacking hnRNP G. Wt hnRNP G markedly inhibited the proliferation capacity, ...
Effect of myocardial revascularisation on left ventricular systolic function in patients with and without viable myocardium: should non-viable segments be revascularised?
(Bmj Publishing Group, London, 2013)
Objective To assess the effect of surgical revascularisation on left ventricular (LV) systolic function in patients with viable and non-viable dysfunctional LV segments determined by low dose dobutamine stress echocardiography ...
Effect of resin and photoinitiator on color, translucency and color stability of conventional and low-shrinkage model composites
(Elsevier Sci Ltd, Oxford, 2016)
Objective. To study the effect of a low-shrinkage methacrylate monomer and monoacylphosphine oxide photoinitiator on color, translucency, and color stability of model resin-based composites (RBCs). Methods. Four micro-hybrid ...
The Y-Chromosome Tree Bursts into Leaf: 13,000 High-Confidence SNPs Covering the Majority of Known Clades
(Oxford Univ Press, Oxford, 2015)
Many studies of human populations have used the male-specific region of the Y chromosome (MSY) as a marker, but MSY sequence variants have traditionally been subject to ascertainment bias. Also, dating of haplogroups has ...
Ferrule Effect: A Literature Review
(Elsevier Science Inc, New York, 2012)
Introduction: Preserving intact coronal and radicular tooth structure, especially maintaining cervical tissue to create a ferrule effect, is considered to be crucial for the optimal biomechanical behavior of restored teeth. ...
Monomer-to-polymer conversion and micro-tensile bond strength to dentine of experimental and commercial adhesives containing diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide or a camphorquinone/amine photo-initiator system
(Elsevier Sci Ltd, Oxford, 2013)
Objectives: To compare the degree of conversion (DC) of adhesives initiated by diphenyl(2,4,6-trimethylbenzoyl) phosphine oxide (TPO) or a camphorquinone/tertiary amine system (CQ/Amine) as well as their 'immediate' ...
