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

open access: yesAustralian 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.

Effects of Calcium Hydroxide Paste and Access Cavities on Fracture Strength of Mature and Simulated Immature Human Teeth: Ex Vivo

open access: yesAustralian 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 ...

Trace Element Patterns in Juvenile Wild Chimpanzee Dentitions

open access: yesArchaeometry, EarlyView.
ABSTRACT Trace elements are used to infer mammalian early‐life diets, environmental toxins, dispersal patterns, stress histories, and weaning ages. Here, we employ laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) to reveal elemental patterns in our closest living relatives, chimpanzees.

Proteomic Sex Estimation From Embedded Tooth Enamel

open access: yesArchaeometry, EarlyView.
ABSTRACT Teeth hold insights into childhood diet, health and demography—including chromosomal sex. Proteomic analysis can detect peptide biomarkers from amelogenin genes encoded on X and Y chromosomes, allowing sex estimation. Embedding resins, necessary for thin sectioning teeth, can damage analytical systems, preventing proteomic analysis. We present

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

open access: yesBoreas, 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 ...

Chromatin Remodeller BRD9 Orchestrates Odontoblastic Differentiation via Coordinating RUNX2‐KLF4

open access: yesCell Proliferation, EarlyView.
During odontoblast lineage commitment, the chromatin remodeller BRD9 acts as a critical epigenetic coordinator, orchestrating the chromatin landscape to facilitate synergistic binding of key transcription factors RUNX2 and KLF4 to target loci for odontogenesis.

Traumatic Dental Injuries as a Potential Predisposing Factor for Invasive Cervical Resorption: A Systematic Review

open access: yesDental Traumatology, EarlyView.
ABSTRACT Invasive cervical resorption is a clinically challenging and often silent form of external root resorption that may remain undetected until substantial structural damage has occurred. Although traumatic dental injuries are repeatedly cited as potential predisposing factors, the strength, consistency, and clinical meaning of this association ...

Host Detection by Cuckoo Bumblebees: Choice Experiments Reveal Non‐Visual Cues Support Host Detection, but Accuracy Is Low

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Female Bombus vestalis cuckoo bumblebees were introduced to a flight arena containing four identical opaque boxes, featuring slits to release volatiles from the bumblebees inside. When only one box contained a developing host colony, the cuckoos were able to locate their hosts among the four boxes with 66.2% accuracy.
