Effect of Whitening Toothpastes on Dentin Abrasion: An In Vitro Study.
To compare the effect of toothbrushing abrasion with hydrated silica-based whitening and regular toothpastes on root dentin using contact profilometry.Ninety dentin specimens (4 x 4 x 2 mm) were randomly divided into five experimental groups (n = 18) according to the toothpaste: three whitening (W1, W2 and W3) and two regular toothpastes (R1 and R2 ...

ABSTRACT Objective This randomized clinical trial evaluated the one‐year color stability and patient satisfaction regarding dental esthetic improvement after 37.5% hydrogen peroxide (37.5HP) in‐office bleaching with a reduced application protocol. Materials and Methods Forty participants with a shade mean C2 or darker were randomly allocated into two ...

Abstract Hydrogen peroxide (HP) at 35% is effective for dental bleaching but may reduce enamel mineral content and induce structural changes. This study developed a bleaching‐hydrogel containing 6%HP and manganese‐oxide–doped Biosilicate (MnO_BioS), activated by violet LED, under in situ conditions.

ABSTRACT Background Pulse oximetry is an accurate diagnostic method for assessing the condition of the dental pulp; however, the normal oxygen saturation levels for each tooth type are yet to be clearly defined. Objectives This systematic review and meta‐analysis aims to answer the question: What are the reference values for pulse oximetry testing in ...

Significative whitening action of five whitening toothpastes
One of the main concerns of patients is to improve their dentaI aesthetics through teeth whitening, which is why there is a big quantity of products in the market that tries to satisfy this requirement with whitening toothpastes offer. To determinate whitening clinic effect of 5 toothpastes in dental teeth, they were arranged 5 treatment groups for ...

Sensory Investigation of Toothpaste Foam Using Rheology and Dynamic Foam Analysis
This study bridges classical foam physics and consumer perception in oral‐care systems. By integrating parent paste yield stress with foam viscoelastic properties and microstructural metrics from a Dynamic Foam Analyzer (DFA), robust models (R2 = 0.8) were established to directly predict consumer‐perceived foam degree.

Cosmetic Enzymes as Formulation‐Integrated Actives: Mechanisms, Delivery, and Functional Evidence
ABSTRACT Background Enzymes are increasingly incorporated into cosmetic formulations as engineered bioactive components whose performance depends on stabilization, delivery, and controlled activity within complex formulation systems, rather than functioning as standalone ingredients. Aims This review examines the mechanisms of action of enzymes used in

A lightweight dual‐branch neural network with cross‐attention fusion (LDCNN‐CF) integrates Mel‐spectrograms with psychoacoustic parameters to predict electric toothbrush acoustic comfort. The model achieves human‐like accuracy (MAE = 0.82, R2 = 0.84) with only 0.42 M parameters and identifies roughness as the dominant predictor of discomfort.
