Diagnostic Accuracy of Dentin Sclerosis by Optical Coherence Tomography and the North Carolina Index in Noncarious Cervical Lesions

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the diagnostic accuracy of optical coherence tomography (OCT) and the North Carolina Index (NCI) for identifying dentin type (sclerotic vs. nonsclerotic) in natural noncarious cervical lesions (NCCLs). Materials and Methods Thirty extracted human premolars with 30 NCCLs (90 regions of interest) were analyzed. Two blinded,

Tooth Sensitivity, Bleaching Efficacy, and Quality of Life in Young People and Adults: A Stratified, Randomized Bi‐Center Study

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives This study compared tooth sensitivity, bleaching efficacy, and the impact on oral health‐related quality of life between at‐home and in‐office tooth bleaching in adults and young individuals. Materials and Methods Eighty participants, 40 young people (14–20 years) and 40 adults (40–60 years), were randomly assigned to receive either

Clinical Study on the Efficacy of 35% Hydrogen Peroxide Gel According to Exposure Time (40 min vs. 20 min) by Spectrophotometry

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To analyze the chromatic effect on CIELAB coordinates and the clinical effectiveness of in‐office whitening treatment (perceptible changes) with 35% hydrogen peroxide (HP) gel according to the number of clinical sessions and exposure time (40 min vs. 20 min) in the three thirds of the tooth.

Pigmentation disorders in three specimens of spiny dogfish, Squalus acanthias Linnaeus, 1758, from the Gulf of Venice, northern Adriatic Sea

open access: yesJournal of Fish Biology, EarlyView.
Abstract This study reports three cases of pigmentation disorders in Squalus acanthias from the Gulf of Venice. Two specimens exhibited spotless phenotypes, whereas one exhibited hypermelanism. Morphological assessments were conducted for two individuals, alongside genetic analysis of mitochondrial genes to determine phylogeographic relationships. Both

The multidimensional regulation roles and mechanisms of calcium in fruit quality

open access: yesJournal of Integrative Plant Biology, EarlyView.
This review explores how calcium signaling molecule integrates plant hormones, environmental cues, and developmental signals to influence external fruit traits, internal nutritional properties, and physiological disorders. ABSTRACT Calcium (Ca2+), a dual‐functional mineral that serves both as an essential structural factor and a signaling molecule ...

A Bayesian approach to spectroscopic depth sectioning for locating dopant atoms

open access: yesJournal of Microscopy, EarlyView.
Abstract Locating dopants in 3D is of great interest as advanced materials and devices increasingly rely on control at atomic dimensions, and microscopy tools are constantly in development for this purpose. One potential tool is electron energy loss spectroscopy (EELS) depth sectioning, where a core‐loss signal is collected as a function of electron ...
