Biocompatibility With Osteogenic Potential of Premixed Bioceramic Cements for Use in Apical Surgery

Australian Endodontic Journal, EarlyView.
ABSTRACT This study investigated the biocompatibility and osteogenic potential of premixed bioceramic cements (PBCs)—CeraPutty, EndoCEM MTA Premixed, Well‐Root PT, and One‐Fil PT Injectable—as alternatives to mineral trioxide aggregate for retrograde filling in endodontic microsurgery.

Effect of cement, sodium silicate, kaolinite and water on the viscosity of the grout

, 2010
Cement, sometimes with/without other binders, is widely used for the stabilization of soil by injection and grouting methods. Chemical grouts and sodium silicate are commonly used worldwide for stabilizing soft soils.

Influence of Delivery Method of Hydraulic Calcium Silicate Cement‐Based Sealer on Void Formation: A Micro‐Computed Tomography Study

Australian Endodontic Journal, EarlyView.
ABSTRACT The aim of this study was to compare three delivery methods of a hydraulic calcium silicate cement‐based sealer by quantifying voids using the single‐cone technique. Forty‐eight human mandibular molars were instrumented and scanned using micro‐computed tomography.

Discuss the Rationale for Minimally Invasive Endodontics and the Merits and Demerits of the Concept

Australian Endodontic Journal, EarlyView.
ABSTRACT Minimally invasive endodontics (MIE) places emphasis on the conservation of sound tooth structure and viable pulp tissue during endodontic procedures such as root canal treatment (RCTx) and vital pulp therapy (VPT). The use of minimal access cavity designs and conservative canal preparation dimensions have been investigated as a way to improve

Mortars From Punic and Hellenistic–Roman Solunto: Materials, Formulations, and Technology

Archaeometry, EarlyView.
ABSTRACT This study presents an archaeometric investigation of 18 hydraulic rendering and bedding mortars from Punic and Hellenistic–Roman Solunto (NW Sicily). The research aimed to characterize raw materials, reconstruct manufacturing sequences, and evaluate technological proficiency through mineralogical and petrochemical analyses.

Materials Characterization and Technological Aspects of Hellenistic Grey Ware Lamps From Nysa‐Scythopolis (Israel): Evidence Suggesting Local Production?

Archaeometry, EarlyView.
ABSTRACT Grey ware lamp fragments and a production waster from Tell Iẓṭabba (Israel) were analyzed to determine their manufacturing technology and provenance. These were compared with a light brown‐orange reference fabric from the same site.

An Uncommon Instance of Egyptian Blue in the “Pigmented Intonachino” of the Fishpond Wall Painting From the Roman Villa of Torre di Pordenone (Northeast Italy)

Archaeometry, EarlyView.
ABSTRACT The increasingly close integration of analytical techniques in the study of Greek and Roman wall paintings has shown that Egyptian blue was a common pigment, widely documented in the production of blue and greenish hues in ancient painted production.

Magnesium (alumino) silicate hydrate formation in low-pH cement paste

, 2019
The manufacture of Portland clinker is an energy intensive process and causes 5 to 8% of the anthropogenic CO2 emissions. The temperature needed to produce a reactive magnesium oxide from magnesite (750-900°C) is much lower than the temperature required ...

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
