Mechanical Agitation Effects on Physical Properties of Calcium-Silicate-Cement Sealers

open access: yes
Endodontic sealers are crucial to achieving a fluid-tight seal within the intricacies of root canal systems. While these sealers have been available in hand-mixed or syringe-mixed formulations, there is now a surge in pre-mixed Calcium-Silicate-Cement ...

Processes and Patterns of Dolomite Precipitation in Aptian Pre‐Salt Deposits of Santos Basin, Brazil

open access: yesJournal of Petroleum Geology, EarlyView.
ABSTRACT The Aptian pre‐salt lacustrine carbonates represent the most significant oil exploration target along the South Atlantic margin. Dolomitization of the Santos Basin Barra Velha Formation (BVF) is critical for reservoir quality, yet its origin, patterns, and evolution remain poorly understood.

Exploring a new Portland cement-free calcium silicate cement —Part 1: Synthesis of dicalcium and tricalcium silicate

open access: yesDental Materials Journal
Mineral trioxide aggregate cement is an excellent pulp-capping material; however, its base Portland cement contains highly toxic elements and is expensive. This study aimed to explore the possibility of using calcium silicate cement without Portland cement.

Estimating past fluid pH and evaporative conditions in Gale crater using terrestrial analog samples from Death Valley, CA

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Boron and lithium have been observed in Ca‐sulfate veins of Gale crater. These elements are highly water mobile and can inform us regarding the aqueous processes that may have taken place in Gale crater. However, the analysis of B in Gale crater is limited to low‐Fe rocks and minerals due to spectral interference of Fe with B in ChemCam data ...

Long‐term stability of conventional non‐regenerative periodontal treatment for furcation defects

open access: yesPeriodontology 2000, EarlyView.
Abstract Background Furcation involvement (FI) in multi‐rooted teeth poses significant challenges in periodontal therapy due to complex anatomy and difficulty in achieving effective maintenance. FI is associated with increased periodontal destruction, especially in sites with narrow furcation entrances and deep root concavities.
