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.
Anderson's fault theory also presents a model for seismic interpretation. [7] This model predicts the dip of faults according to their regime classification. [2] Conjugate walls in any fault will share a dip angle with that angle being measured from the top of the hanging wall or the bottom of the foot wall. [2]
A 1930s poster from the Work Projects Administration promoting oral hygiene. Tooth decay is the most common global disease. [14] Over 80% of cavities occur inside fissures in teeth where brushing cannot reach food left trapped after eating and saliva and fluoride have no access to neutralize acid and remineralize demineralized teeth, unlike easy-to-clean parts of the tooth, where fewer ...
Philip Warren Anderson ForMemRS HonFInstP (December 13, 1923 – March 29, 2020) was an American theoretical physicist and Nobel laureate.Anderson made contributions to the theories of localization, antiferromagnetism, symmetry breaking (including a paper in 1962 discussing symmetry breaking in particle physics, leading to the development of the Standard Model around 10 years later), and high ...
Toothpaste is used to promote oral hygiene: it is an abrasive that aids in removing dental plaque and food from the teeth, assists in suppressing halitosis, and delivers active ingredients (most commonly fluoride) to help prevent tooth decay (dental caries) and gum disease . [1]

A cavity starts in a tooth's outer enamel and spreads to the dentin and pulp inside. The goal of water fluoridation is to prevent tooth decay by adjusting the concentration of fluoride in public water supplies. [2] Tooth decay (dental caries) is one of the most prevalent chronic diseases worldwide. [30]
Bottom teeth of a seven-year-old, showing primary teeth (left), a lost primary tooth (middle), and a permanent tooth (right) Tooth eruption in humans is a process in tooth development in which the teeth enter the mouth and become visible. Current research indicates that the periodontal ligaments play an important role in tooth eruption.
