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]
Since dental floss is able to remove some inter-proximal plaque, frequent regular dental flossing will reduce inter-proximal caries and periodontal disease risks. [1] [3] Results of a high level of evidence meta-analysis recently found that floss may not be the most effective method for interdental cleaning, contrary to common belief at the ...

In dentistry, debridement refers to the removal by dental cleaning of accumulations of plaque and calculus (tartar) in order to maintain dental health. [1] Debridement may be performed using ultrasonic instruments, which fracture the calculus, thereby facilitating its removal, as well as hand tools, including periodontal scaler and curettes, or through the use of chemicals such as hydrogen ...
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 ...
[3] 4-Methacryloyloxyethyl trimellitic acid anhydride (4-META) that adheres to not only tooth structures but also dental alloys, was developed almost at the same time. [4] In order to create adhesive monomers having higher performance, investigation and optimization of adhesive monomer molecular structure was carried out.
Dental impressions are negative imprints of teeth and oral soft tissues from which a positive representation can be cast. They are used in prosthodontics (to make dentures), orthodontics, restorative dentistry, dental implantology and oral and maxillofacial surgery. [3]: 136–137
All-in-one self-etch adhesive and a single component universal adhesive, used in the adhesion of direct and indirect dental restorations. Also known as a "bonderizer" bonding agents (spelled dentin bonding agents in American English) are resin materials used to make a dental composite filling material adhere to both dentin and enamel.
