It may be prepared via the Schiemann reaction, in which a 4-aminobenzoic acid, protected as the ethyl ester, is diazotised and then fluoride introduced using tetrafluoroborate. Hydrolysis of the ester converts it back to the free acid. [2] 4-Fluorobenzoic acid has been observed to form by the aerobic biotransformation of 4-fluorocinnamic acid. [3]
The high affinity to tooth mineral is based on matching distances of Ca-ion binding sites on P11-4 and Ca spacing in the crystal lattice of hydroxyapatite. The matrix formation is pH controlled and thus allows control matrix activity and place of formation. [36] Self assembling properties of P11-4 are used to regenerate early caries lesions.

Atraumatic restorative treatment (ART) – operative and preventive caries management through the use of the ART approach (sealants and fillings), introduction of dental care to young children and patients with dental fear or anxiety, presenting with mental or physical disabilities or home-bound elderly and those stay in nursing homes; and ART ...
Fluoride therapy is the use of fluoride for medical purposes. [2] Fluoride supplements are recommended to prevent tooth decay in children older than six months in areas where the drinking water is low in fluoride. [3] It is typically used as a liquid, pill, or paste by mouth. [4] Fluoride has also been used to treat a number of bone diseases. [5]
They are used in prosthodontics (to make dentures), orthodontics, restorative dentistry, dental implantology and oral and maxillofacial surgery. [3]: 136–137 Because patients' soft-tissue undercuts may be shallow or deep, impression materials vary in their rigidity in order to obtain an accurate impression.
The perception of tooth colour is multi-factorial. Reflection and absorption of light by the tooth can be influenced by a number of factors including specular transmission of light through the tooth; specular reflection at the surface; diffuse light reflection at the surface; absorption and scattering of light within the dental tissues; enamel mineral content; enamel thickness; dentine colour ...
