Success of Primary Teeth Pulpotomy Using Calcium Silicate Cements: A Systematic Review and Meta-Analysis of Randomized Clinical Trials.

The purpose of this systematic review and meta-analysis was to assess the success of pulpotomies performed on primary teeth using mineral trioxide aggregate (MTA) and other calcium-silicate-based cements (CSC). A comprehensive search was conducted in six electronic databases. The selection of studies was guided by PICOS criteria and included only randomized clinical trials that evaluated the success of pulpotomy in primary teeth using MTA, compared with other CSC materials.

A meta-analysis of calcium silicate-based cements and calcium hydroxide as promoters of hard tissue bridge formation.

Background: The formation of a reparative hard tissue bridge is a key indicator of defensive pulp response and successful vital pulp treatment (VPT); however, there is a lack of comprehensive information regarding the impact of bioactive materials on hard tissue formation.

Objectives: This systematic review with meta-analyses aimed to evaluate the hard tissue bridge formation in direct pulp capping and pulpotomies in humans, comparing the use of ProRoot MTA with other calcium silicate-based cements (CSCs) and calcium hydroxide.

Methods: The search was conducted in six electronic databases, until May 2024.

Radiomic analysis of abdominal organs during sepsis of digestive origin in a French intensive care unit.

Background: Sepsis is a severe and common cause of admission to the intensive care unit (ICU). Radiomic analysis (RA) may predict organ failure and patient outcomes. The objective of this study was to assess a model of RA and to evaluate its performance in predicting in-ICU mortality and acute kidney injury (AKI) during abdominal sepsis.

Uptake of Hydrogen Peroxide from the Gas Phase to Grain Boundaries: A Source in Snow and Ice.

Hydrogen peroxide is a primary atmospheric oxidant significant in terminating gas-phase chemistry and sulfate formation in the condensed phase. Laboratory experiments have shown an unexpected oxidation acceleration by hydrogen peroxide in grain boundaries. While grain boundaries are frequent in natural snow and ice and are known to host impurities, it remains unclear how and to which extent hydrogen peroxide enters this reservoir.

Optimal location for fibular osteotomy to provide maximal compression to the tibia in the management of delayed union and hypertrophic non-union of the tibia.

Background: Tibial shaft fractures are the commonest long bone fracture, with early weight-bearing improving the rate of bony union. However, an intact fibula can act as a strut that splints the tibial segments and holds them apart. A fibular osteotomy, in which a 2.
