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.

Effect of Kinematics and Speed on Filling Material Removal, Canal Transportation, and Apical Extrusion During Retreatment of Curved Canals

Australian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated the effects of kinematics (reciprocating vs. continuous rotation) and rotational speed (350 vs. 1200 rpm) on filling removal, canal transportation, and apical extrusion during retreatment of curved root canals. Vertucci type II mesial roots of mandibular molars were prepared, filled, and scanned by micro‐computed ...

Electrosynthesis of Sodium Hypochlorite Using Ion Exchange Membrane

Chemical Engineering Transactions
In this article, we report on a newly designed insitu sodium hypochlorite generation process at laboratory scale. An anion exchange membrane was placed between two cation exchange membranes, dividing the cell into distinct compartments.

Changes in the Location of the Second Mesiobuccal Canal Orifice After Canal Preparation in Maxillary First Molars

Australian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated angular and linear positional changes of the second mesiobuccal (MB2) canal orifice in maxillary first molars and proposed a guideline for its localization. Twenty‐eight extracted maxillary first molars with four canals were analysed. After access cavity preparation, all canals except MB2 were instrumented. The initial and

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 ...

Sodium Diclofenac‐Loaded Drug Delivery Microspheres: Impact on Calcium Hydroxide Paste Properties and Biological Response

Australian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated whether the incorporation of sodium diclofenac‐loaded microspheres into a calcium hydroxide paste enhances antibiofilm activity while maintaining physicochemical properties and biocompatibility. Calcium hydroxide paste, calcium hydroxide combined with sodium diclofenac, and calcium hydroxide containing sodium diclofenac ...

Ecological variability of Hippopotamus antiquus from the late Early–Middle Pleistocene of Megalopolis Basin (Greece): Evidence for dynamic habitats in a glacial microrefugium

Boreas, EarlyView.
This study investigates the ecology of the extinct European Hippopotamus from the late Early–Middle Pleistocene (c. 900–400 ka) sequence of the Megalopolis Basin, a glacial microrefugium for temperate taxa in southern Greece. Using stable carbon (δ13C) and oxygen (δ18O) isotope analyses and microwear analyses of Hippopotamus dental elements, we ...

A revised classification system of the marronoid clade of spiders (Araneae), based on dense sampling phylogenomics and comparative morphology

Cladistics, EarlyView.
Abstract The marronoid clade is a globally distributed, ecologically diverse group of spiders. It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to the widespread character ...

Mitigating the human link in emerging reptile fungal pathogen transmission

Conservation Biology, EarlyView.
Abstract Handling wild reptiles is common among amateur herpetology enthusiasts, professional researchers, social media influencers, and photographers. However, the potential for these interactions to spread diseases that threaten wild reptiles remains underappreciated.

Delipidisation of wool fibres and the subsequent beneficial properties of delipidised wool fibres

Coloration Technology, EarlyView.
Abstract Wool fibres are complex matrices of proteins and fatty acids/lipids found both internally and externally. 18‐methyleicosanoic acid (18‐MEA) is covalently bound to the surface of the fibre via a thio‐ester link, and is considered one of the most important lipids as it is responsible for the hydrophobic properties of wool fibres.
