Prenatal opioid exposure, and health, social and educational outcomes for school‐aged children: A systematic review

Addiction, EarlyView.
Abstract Background and aims Recent decades have seen a rise in the number of pregnancies exposed to opioids. Whilst evidence of the impact of such exposure on pregnancy and infant outcomes is fairly robust, the impact of prenatal opioid exposure (POE) on longer‐term outcomes for children and young people remains unclear.

Surface Physical and Mechanical Properties of Short Fibre Reinforced Composite Resins in Direct Restorative Dentistry: A Systematic Review

Australian Dental Journal, EarlyView.
ABSTRACT Background Short Fibre Reinforced Composite resins may be used to restore odontogenic tissues and have enhanced physical and mechanical properties compared with conventional resins. However, their surface characteristics remain a concern, and this has limited their use as direct dental restorative materials.

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

Investigating relationships among strontium, barium, and seasonality in wild baboons

Archaeometry, EarlyView.
Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...

Morphometric and Paleobiological Insights Into Pleistocene Sicilian Wolf Populations

Acta Zoologica, EarlyView.
ABSTRACT The Pleistocene wolves (Canis lupus) from Sicily represent one of the few known insular populations of this species from that time period. Despite their potential relevance for understanding carnivore adaptations in insular contexts, no dedicated study has previously investigated their morphology and evolutionary significance.

Unravelling the phylogeny of armadillos and their kin (Mammalia, Xenarthra, Cingulata) combining morphological, molecular, and stratigraphic data

Cladistics, EarlyView.
Abstract Cingulata, a major lineage of Xenarthra, comprises extinct and extant armoured placental mammals that diversified throughout the Cenozoic. Despite extensive study, phylogenetic hypotheses based on morphological and molecular data remain incongruent, and no total evidence analysis has been conducted. Here, we integrate the largest morphological
