Recent progress in studies of the last million years of human physical and behavioural evolution Avancées récentes dans l’étude du dernier million d'années d’évolution physique et éthologique de l'espèce humaine

Journal of the Royal Anthropological Institute, EarlyView.
This article presents a synthesis of recent developments in the study of human evolution over the past five years. It begins with an overview of hominin species nomenclature and diversity, followed by an examination of the proposed population bottleneck ∼900,000 years ago.

Low‐Concentration Mineralization‐Promoting Peptide‐3–Containing Slurries Compared With Casein Phosphopeptide–Amorphous Calcium Phosphate on Demineralized Permanent Enamel: An Exploratory Ex Vivo Study

Australian Dental Journal, EarlyView.
ABSTRACT Background Casein phosphopeptide–amorphous calcium phosphate is a biomimetic remineralizing agent but is unsuitable for individuals with a milk‐protein allergy. This exploratory ex vivo study compared low‐concentration slurries containing mineralization‐promoting peptide‐3, sodium fluoride plus mineralization‐promoting peptide‐3, vehicle cream

Evaluation of the Adequate Radiopacity of Cavity Lining/Base and Core Build‐Up Light Cured Composite Resins

Australian Dental Journal, EarlyView.
ABSTRACT Background This study aimed to compare the radiopacity of composite resins (CR) used as lining, base, and core‐build up materials with enamel and dentine and evaluate their compliance with ISO 4049. Methods Specimens of 1, 2, and 3 mm thicknesses; (n = 6) were fabricated from 13 low‐viscosity and 10 regular‐viscosity CRs.

Artificial Intelligence and Digital Impressions: The Positives and the Pitfalls

Australian Dental Journal, EarlyView.
ABSTRACT Digital impressions are now central to contemporary dental workflows, driven by advances in CAD/CAM manufacturing and intraoral scanning technologies. In parallel, rapid progress in artificial intelligence (AI)—particularly deep learning—has led to its widespread integration into digital impression systems.

Is Cone‐Beam CT Reliable for Apical Foramen Assessment? A Micro‐CT–Referenced Study

Australian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated the diagnostic accuracy of two cone‐beam CT (CBCT) dose protocols for identifying the number and trajectory deviation of apical foramina. Forty lower molars were scanned in Micro‐CT. Thereafter, all teeth were inserted into the mandible sockets and a titanium implant and an endodontically treated tooth with a cobalt ...

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 ...
