Systematic reviews and meta-analyses often examine data from diverse taxa to identify general patterns of effect sizes. Meta-analyses that focus on identifying generalisations in a single taxon are also valuable because species in a taxon are more likely to share similar unique constraints. We conducted a comprehensive phylogenetic meta-analysis of flight initiation distance in lizards. Flight ...

The question of whether a species matches the colour of its natural background in the perspective of the correct receiver is complex to address for several reasons; however, the answer to this question may provide invaluable support for functional interpretations of colour. In most cases, little is known about the identity and visual sensory abilities of the correct receiver and the precise loc...

AIM To review the literature on the sealing ability of esthetic post systems with different cementation techniques. BACKGROUND An important factor for successful root canal treatment is the development of a coronal seal to the treated root canal system. Review result: The current literature describes promising results using fiber posts with a dual-cure, self-etch resin cement system. However,...

OBJECTIVES To assess compressive strength and effect of duration after photoactivation on the compressive strength of different dual cure bulk fill composites. METHODS Seventy-two disc shaped (4x10mm) specimens were prepared from three dual cure bulk fill materials, ZirconCore (ZC) (n=24), MulticCore Flow (MC) (n=24) and Luxacore Dual (LC) (n=24). Half of the specimens in each material were t...

Purpose: The aim of the study was to evaluate shear bond strength (SBS) different resin cements after zirconia surface treatments. Materials & Methods: A total 60 discs (3x7mm) were prepared and divided into 3 main groups according treatments as control (C), sandblasting (SB), tribochemical silica coating (TC). Main two subgroups applied. No treatment applied samples in C group. 50μm Al2O3 ...

OBJECTIVES This retrospective study investigated the clinical effectiveness over up to 8 years of parallel-sided and of tapered glass-fiber posts, in combination with either hybrid composite or dual-cure composite resin core material, in endodontically treated, maxillary anterior teeth covered with full-ceramic crowns. METHODS The study population comprised 192 patients and 526 endodontically...

For a decade following the initial description of dual amoxicillin–proton pump inhibitor (PPI) therapy by Unge et al.,[1] investigators attempted to optimize the doses and duration of this regimen in an attempt to reliably achieve >90% cure rates (reviewed in Dore et al.).[2] When given twice daily PPI and amoxicillin cured approximately 62% patients (range 60–64%),[3] and increasing the omepra...
