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 ...
Biological evaluation of two hydroxy-apatite materials.

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 ...
Periodontal Therapy Improves Gastric Helicobacter pylori Eradication
(Sage Publications Inc, Thousand Oaks, 2009)
The oral cavity has been proposed as a reservoir for H. pylori that could be responsible for the refractoriness of gastric infection to triple therapy (antibiotics, antimicrobials, and proton pump inhibitors). The aim of ...
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' ...
The influence of three different apical implant designs at stability and osseointegration process: experimental study in rabbits
(Wiley, Hoboken, 2017)
Objectives: The aim of this study was to perform a histomorphometric and biomechanical comparison of three implants with different designs of the apical area to promote a better bone initial stability and its correlation ...
Degree of conversion and monomer elution of CQ/amine and TPO adhesives
(Elsevier Sci Ltd, Oxford, 2014)
Objective. To evaluate the effect of photo-initiator on the degree of conversion (DC) and elution of Bis-GMA and HEMA for 8 one-step adhesive formulations. Methods. We used Scotchbond Universal ('SBU-CQ/amine 4.0', 3M ...
Dental implant surgery in patients in treatment with the anticoagulant oral rivaroxaban
(Wiley, Hoboken, 2016)
Objectives: The aim of this study was to evaluate the incidence of bleeding complications after dental implant placement in patients in treatment by the anticoagulant oral rivaroxaban without interrupting its administration ...
Histopathological comparative analysis of peri-implant soft tissue response after dental implant placement with flap and flapless surgical technique. Experimental study in pigs
(Wiley, Hoboken, 2015)
AimThe aim of this study was comparing the effect of flapless vs. flap technique of implant placement on inflammation degree of peri-implant soft tissue, through histopathological analysis. MethodThe experiment was conducted ...
