Impact of Chelators on FAC Following Interaction With NaOCl: A Focused Evidence Synthesis Based on a Systematic Search

Australian Endodontic Journal, EarlyView.
ABSTRACT This systematic review following PRISMA guidelines evaluated the effects of endodontic chelators on free available chlorine (FAC) in sodium hypochlorite (NaOCl), with emphasis on the influence of concentration, contact time, temperature, and pH. Risk of bias was assessed using the Quality Assessment Tool for In Vitro Studies (QUIN).

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 ...

A randomised clinical in situ study to evaluate the effects of novel low abrasivity anti-sensitivity dentifrices on dentine wear [PDF]

, 2017
Objectives: To compare the abrasive wear on human dentine in an in situ model associated with use of an experimental low abrasivity anti-sensitivity dentifrice containing 1% alumina and 5% sodium tripolyphosphate (STP) with an experimental ultra-low ...

Trace Element Patterns in Juvenile Wild Chimpanzee Dentitions

Archaeometry, 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

Archaeometry, 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

Randomised clinical studies investigating immediate and short-term efficacy of an occluding toothpaste in providing dentine hypersensitivity relief

BMC Oral Health, 2019
Background Dentine hypersensitivity (DH) can occur after gum recession or enamel loss and may impact quality of life. Treatments include toothpastes that decrease DH by occluding dentine tubules.

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

Boreas, 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 ...
