Neural Networks and Multivariate Analysis Based on Geochemical Data to Determine Stone Provenance From Ancient Calabrian Quarries (Southern Italy)

Archaeometry, EarlyView.
ABSTRACT This study shows an innovative approach to determine the origin of some Calabrian rocks quarried used in ancient times. Twenty‐five quarries, distributed in all the Calabrian provinces (Southern Italy), were studied and sampled. Ten samples were taken from each quarry, for a total of 250 samples.

Artificial Intelligence in the Detection of Clinically Negotiable Second Mesio‐Buccal Canals in Periapical Images of Maxillary Molars

International Endodontic Journal, EarlyView.
ABSTRACT Aim Artificial intelligence (AI) has the potential to aid clinicians in assessing case difficulty in endodontics. The objectives of this study were to develop and validate deep learning models for the detection of clinically negotiable MB2 canals in periapical images of maxillary first and second molars, and to compare the performance of AI ...

Ultra‐High‐Speed Sintering of 3.5Y‐TZP Zirconia: Time Reduction Without Compromising Translucency

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To assess, firstly, the impact of three sintering speeds on translucency and grain size of 3.5Y‐TZP zirconia (Katana HT) across clinically relevant thicknesses, and secondly, the effect of thermocycling on translucency. Materials and Methods Disc specimens were fabricated at six thicknesses (0.7–2.0 mm) and sintered using SLOW (7 h),

Harnessing the Therapeutic Potential of Cell Secretomes and Extracellular Vesicles for Craniofacial Regenerative Applications

Journal of Periodontal Research, EarlyView.
The scoping review summarizes the current preclinical and clinical evidence for the use of “cell‐free” therapies in craniofacial (periodontal, bone and soft‐tissue) regeneration. It also aims to highlight key challenges and strategies towards the clinical translation of these therapies.

Reciprocal transport of carbon and nitrogen between plants and the hyphosphere microbiome in a temperate grassland

New Phytologist, EarlyView.
Overview of the experimental design and 13CO2 pulse‐labeling approach in the field. Summary Despite its relevance for plant nutrient acquisition, the role of the hyphosphere in structuring fungal–bacterial networks and mediating carbon–nitrogen (C–N) exchange under field conditions remains unclear.
