In various studies the use of nano hydroxyapatite in toothpaste showed positive results in aiding the remineralisation of dental enamel. [32] In addition to remineralisation, in vitro studies have shown that toothpastes containing nano-hydroxyapatite have the potential to reduce biofilm formation on both tooth enamel and resin-based composite ...
Tooth enamel consists mostly of calcium hydroxyphosphate, Ca 5 (PO 4) 3 OH, also known as the mineral hydroxyapatite. Apatite is a hard, insoluble compound. Apatite is a hard, insoluble compound. Acid (H + ), produced especially after a high-sugar meal, attacks the apatite:
This discussion of the dental amalgam controversy outlines the debate over whether dental amalgam (the mercury alloy in dental fillings) should be used. Supporters claim that it is safe, effective and long-lasting, while critics argue that amalgam is unsafe because it may cause mercury poisoning and other toxicity. [1] [2] [3]
Dental caries result when the demineralization rate is faster than the remineralization, producing net mineral loss, which occurs when there is an ecologic shift within the dental biofilm from a balanced population of microorganisms to a population that produces acids and can survive in an acid environment.
Enamel is the hardest substance in the human body and contains the highest percentage of minerals (at 96%), [2] with water and organic material composing the rest. [3] The primary mineral is hydroxyapatite, which is a crystalline calcium phosphate. [4]
Aspirational beauty content and the high cost of dental care is pushing some people to fix their teeth using viral DIY dental hacks, risking long term damage. DIY dental 'hacks' keep going viral ...
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]
[20] [22] About 84.9% of dental practitioners among those attending a health screening program in the annual ADA session in San Francisco, California, were found to restore teeth with 100–200 dental amalgam restorations in a week, and about 4.2% did a minimum of 50 dental amalgam fillings in a week.
