The subsurface lesion in erosive tooth wear

Journal of Dentistry, 2023
This study compared the surface change on natural and polished enamel exposed to a joint mechanical and chemical wear regimen.Human enamel samples were randomly assigned to natural (n = 30) or polished (n = 30) groups, subjected to erosion (n = 10, 0.3% citric acid, 5 min), abrasion (n = 10, 30 s), or a combination (n = 10).

Structural Porosity and Low Mineral Density in Enamel Rods Drive Molar Incisor Hypomineralisation

Advanced Functional Materials, EarlyView.
This study uses advanced imaging modalities on multiple length scales to show that molar‐incisor hypomineralization does not present as a locally homogeneous pathology. Instead, microstructural defects, characterized through non‐mineralized, protein‐rich sheaths and an altered mineral structure in between prism rods, resulting in local differences in ...

Case Report: Case report: Rapidly progressing tooth wear dominated by intrinsic and extrinsic erosion [version 2; peer review: 2 approved]

F1000Research
Tooth wear is multi-factorial presenting as a combination of abrasion, attrition, and erosion. This case report represents a case of combined tooth wear in a 46-year-old Indo-Trinidadian male, with a predominant erosive component with both the clinical ...

Is Adding TiF4 in Supply Water a Viable Measure for the Control of Dental Erosion?

Dental Hypotheses, 2018
Introduction: The prevention of tooth erosion, progressive and irreversible loss of hard dental tissue due to the chemical process without bacterial involvement, can be mediated by the use of fluoride compounds with incorporation of titanium.

Is prolonged bleaching more harmful to dental enamel than daily dietary and hygienic oral habits?

Brazilian Oral Research, 2021
The ultrastructural and mechanical properties of enamel surface were evaluated after prolonged bleaching treatments with 10% carbamide peroxide in the presence or absence of orange juice (erosive challenge) and toothbrushing (abrasive challenge).

Scanning Electrochemical Microscopy as a Tool for the Characterization of Dental Erosion

International Journal of Electrochemistry, 2011
When the tooth is exposed to acidic environments, an irreversible loss of dental hard tissue occurs in a process called dental erosion. In this work, the scanning electrochemical microscopy (SECM) was used to probe the consumption of protons at the ...
