Edemogenic test and hydrogen peroxide degradation rate of bleaching gels with different desensitizing agents

open access: yesBrazilian Dental Science, 2018
Objective: The at-home bleaching technique leads to the intimate contact of the bleaching gel with gingival tissues, so this study evaluated the immediate inflammatory response, through the edemogenic test, induced by at-home bleaching gels of 10 ...

The composition of the dental pellicle: an updated literature review

open access: yesFrontiers in Oral Health, 2023
BackgroundThe dental pellicle is a thin layer of up to several hundred nm in thickness, covering the tooth surface. It is known to protect the teeth from acid attacks through its selective permeability and it is involved in the remineralization process ...

Simulation Study on the Magnetic Field Characteristics of a Permanent Magnet Motor for a Rim-Driven Device

open access: yesApplied Sciences
The rim-driven device (RDD) integrates the motor and the impeller, which can achieve shaftless, modular, and integrated operation of the turbomachinery system and has broad application prospects. To reduce the axial length and radial thickness of the RDD,

Pathogenesis of Molar Hypomineralisation: Aged Albumin Demarcates Chalky Regions of Hypomineralised Enamel

open access: yesFrontiers in Physiology, 2020
Molar hypomineralisation (MH) is becoming globally recognised as a significant public health problem linked to childhood tooth decay. However, with causation and pathogenesis unclear after 100 years of investigation, better pathological understanding is ...

Suppression of Cogging Torque for Line-start Permanent Magnet Synchronous Motor

open access: yesJournal of Harbin University of Science and Technology
The stator and rotor of line-start permanent magnet synchronous motor ( LSPMSM) are slotted on both sides, which greatly increases the difficulty of analyzing the characteristics of cogging torque of LSPMSM and studying its suppression methods.

Effect of the pulpal hydrostatic pressure on the morphological data of the fluid droplets emerging from dental enamel in human teeth

open access: yesData in Brief, 2020
Enamel fluid in human teeth plays an important role in the permeability and mechanical property of the enamel. It can be invetigated as fluid droplets at the enamel surface by using the replica technique.

Effect of bleaching agents containing fluoride or calcium on enamel microhardness, roughness and permeability

open access: yesBrazilian Journal of Oral Sciences, 2016
Aim: To evaluate the effect of different in-office bleaching agents on the permeability, roughness and surface microhardness of human enamel. Methods: For evaluation of roughness and microhardness, 40 hemi-faces of 20 premolars were subjected to initial ...

Modified Titanium Dental Implants: The Current Progress of Soft‐Tissue Integration Methods

open access: yesAdvanced NanoBiomed Research, EarlyView.
Dental implants are an established solution for tooth loss, yet achieving soft tissue integration (STI) around the transmucosal region remains a challenge. The natural tooth–gingiva interface is poorly replicated on titanium implants. This review explores surface modification strategies, ranging from surface chemistry and topography to biological ...
