Tooth remineralization is the natural repair process for non-cavitated tooth lesions, [1] [2] in which calcium, phosphate and sometimes fluoride ions are deposited into crystal voids in demineralised enamel. Remineralization can contribute towards restoring strength and function within tooth structure.
The enamel on primary teeth has a more opaque crystalline form and thus appears whiter than on permanent teeth. The large amount of mineral in enamel accounts not only for its strength but also for its brittleness. [6] Tooth enamel ranks 5 on Mohs hardness scale (between steel and titanium) and has a Young's modulus of 83 GPa. [4]
Amelogenesis imperfecta, which occurs in between 1 in 718 and 1 in 14,000 individuals, is a disease in which the enamel does not fully form or forms in insufficient amounts and can fall off a tooth. [42] In both cases, teeth may be left more vulnerable to decay because the enamel is not able to protect the tooth. [43]
In the event that you do touch a surface that is contaminated with live COVID-19 droplets, if you proceed to touch your nose, eyes, or mouth, you are “taking the virus from the surface and ...
Molar incisor hypomineralisation (MIH) is a type of enamel defect affecting, as the name suggests, the first molars and incisors in the permanent dentition. [1] MIH is considered a worldwide problem with a global prevalence of 12.9% and is usually identified in children under 10 years old. [2]
Plane-form enamel hypoplasia is a dental condition that is distinguished by defects in the teeth enamel, that can occur due to genetic or environmental factors. It is common for the disease to occur during the developmental stages of the teeth, and childhood illnesses, such as respiratory infections, are often linked to disturbance of the enamel formation [5] [6].
Lining materials protect the weak tooth from post-operative hypersensitivity, reducing patient discomfort and allowing the tooth to heal at a faster rate after the procedure. [ 5 ] Some dental restorative materials, such as acrylic monomers in resin-based materials and phosphoric acid in silicate materials, may pose toxic and irritable effects ...
As the age of the person increases, the teeth can also appear yellower over time. [15] Below are examples of intrinsic sources of stains: Tooth wear and aging: Tooth wear is a progressive loss of enamel and dentine due to tooth erosion, abrasion and attrition. As enamel wears down, dentine becomes more apparent and chromogenic agents are ...
