Geological Substrate Is Related to Tooth Senescence and Population Dynamic: The Case Study of Alpine Chamois (Rupicapra rupicapra L.)

open access: yesIntegrative Zoology, EarlyView.
In Alpine chamois, the complete wear of the first molar coincides with the beginning of senescence and the progress of tooth wear on calcareous substrate is slower than the one on other substrates, increasing life expectancy. Thus, the first molar wear may actually be considered as an effective descriptor of senescence stage.

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

open access: yesIntegrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Characterisation of the Mesial Root and Middle Mesial Canal Morphology in Mandibular First Molars: An Ex Vivo Micro‐CT Study

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT This ex vivo study characterised the mesial root morphology of mandibular first molars with a middle mesial canal (MMC) using micro‐CT. Among 469 scanned molars, 42 (8.96%) presented an MMC. Morphological parameters analysed included canal configuration, chamber orifice features, dentine thickness, isthmus type, and aspect ratio.

Effect of Endodontic Sealers on the Bond Strength of Glass Fibre Posts: A Systematic Review

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT This systematic review evaluated the influence of resin‐based, eugenol‐based and bioceramic endodontic sealers on the bond strength of glass fibre posts cemented with resin cements. Searches were conducted in PubMed, Scopus, Web of Science, Cochrane Library, Google Scholar and Embase, including in vitro studies using human or bovine teeth ...

A tool-supported approach to inter-tabular verification. [PDF]

open access: yes
The use of decision tables to verify KBS has been advocated several times in the V&V literature. However, one of the main drawbacks of those system is that they fail to detect anomalies which occur over rule chains. In a decision table based context this

Enterococcus faecalis and Endodontic Treatment Failure: A Qualitative Systematic Review of Its Role and Elimination Strategies

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT The aim of this study was to synthesize evidence on the influence of Enterococcus faecalis on endodontic treatment failure and strategies for its elimination. This study followed the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines and was registered in PROSPERO (CRD420251022741).

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

open access: yesArchaeometry, 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 ...

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.

Is Obesity Associated With Dental Caries in Primary Dentition? Findings From a Birth Cohort in Southern Brazil

open access: yesCommunity Dentistry and Oral Epidemiology, EarlyView.
ABSTRACT Objectives Nutritional disorders and dental caries share common risk factors, including diet and socioeconomic position, but the association between these two conditions remains unclear. The aim of this study was to investigate the potential association between overweight/obesity and the occurrence of dental caries in primary dentition ...
