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

Archaeometry, EarlyView.ABSTRACT Lake sediments are natural archives of past environmental dynamics and how these systems have responded to past climate variability. Sediment geochemistry, governed by local geology and climate processes, is unique to each lake‐catchment and geochemical proxies must be validated for each study site.

Contact Dermatitis, EarlyView.Gold release from gold‐plated earrings was investigated using a cysteine‐modified artificial sweat solution designed to reflect biochemically relevant conditions. This model enabled detection of low‐level gold release. Nickel release was quantified in parallel and was detected in all samples, frequently exceeding established regulatory limits. ABSTRACT

International Endodontic Journal, EarlyView.ABSTRACT Objectives To assimilate data from individual randomised trials and perform a pooled analysis of short‐term outcomes of pulpotomy compared with root canal treatment (RCT) for teeth with symptomatic irreversible pulpitis (SIRP). Methods Randomised trials were conducted in eight countries using a standardised clinical protocol and outcome ...

Nanoprecipitate characterisation in NiTi and aluminium alloys: A TEM‐based overview
Journal of Microscopy, EarlyView.Abstract Nanoscale precipitates are central to the functional and mechanical performance of many advanced alloys, yet their characteristics and spatial distributions can be directly resolved only by electron microscopy. In this poster‐style article, focused ion beam‐prepared TEM lamellae are used to provide a microscopy‐focused overview of ...

Journal of Prosthodontics, EarlyView.Abstract Purpose In metal–ceramic restorations, the substructure fabrication method and design may affect the prognosis of the prosthesis. This study evaluated and compared the fracture resistance of metal–ceramic restorations fabricated with different substructure fabrication methods using two different alloy powders and designs.
