Effects of Calcium Hydroxide Paste and Access Cavities on Fracture Strength of Mature and Simulated Immature Human Teeth: Ex Vivo

Australian Endodontic Journal, EarlyView.
ABSTRACT The aim was to examine whether a Ca(OH)2 paste affects fracture strength of teeth. Sixty extracted maxillary central incisors were prepared to simulate immature teeth. Another 40 were used as mature teeth. The ten groups (n = 10) were: (1) immature control; (2) immature + access; (3) immature + access + 1 m Ca(OH)2; (4) immature + access + 12 ...

The Massif Central as a Centre of Roman Brass Production? New Geochemical Data of the So‐Called Hemmoor Buckets

Archaeometry, EarlyView.
ABSTRACT New analytical data of the so‐called Hemmoor buckets, a group of brass vessels from the Roman period of the 2nd to 3rd century ad that are widespread throughout central and eastern Europe, show considerable similarities with the polymetallic Cévennes ore deposits in south‐eastern France in terms of their geochemical characteristics and lead ...

Without Scratching the Surface: Depth Profiling Compositional Muon Analysis of Ancient Faience From Egypt and Sudan

Archaeometry, EarlyView.
ABSTRACT The specific depth‐profiling capabilities of the muonic x‐ray emission spectroscopy (μ‐XES) technique have proved to be effective for examination of the elemental distribution within ancient coins. This ‘layered’ analysis can also be applied to the examination of ancient faience, the production of which can result in distinct layers (glaze ...

The Materiality of the Cloggs Cave Rockshelter's Painting, GunaiKurnai Country (East Gipplsland), Southeastern Australia

Archaeometry, EarlyView.
ABSTRACT The materiality of the white pigment motif at the Cloggs Cave rockshelter, near Buchan in GunaiKurnai Country (southeastern Australia), contains details about the cultural and environmental contexts in which the art was created and preserved. Here, we (1) present physicochemical analyses of the pigment composition; (2) explore implications for

Deindustrialization and demographic change: Evidence from big plant closures and downsizing

Canadian Journal of Economics/Revue canadienne d'économique, EarlyView.
Abstract We estimate the causal effect of big manufacturing plant closures and downsizing on the socioeconomic composition of Canadian cities between 2001 and 2021. Our instrumental variables estimates show that big manufacturing plant closures and downsizing—large local labour demand shocks—lead to less population growth and a shift in the demographic

Esthetic and adhesive properties of a novel colored fiber post: A restorative approach to an endodontic challenge

European Journal of Oral Sciences, EarlyView.
Abstract Colored fiber posts facilitate clinical retrieval but could impact esthetics and bonding. This study evaluated the color stability and dentin bond strength of a novel colored fiber post designed to facilitate post‐removal. Sixty premolars had root canal therapy and post space preparation.
