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 ...

[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.
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 ...
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 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.
However, Pierre Fauchard, the father of modern dentistry, is credited for the introduction of tooth polishing to remove dental stains. Early polishing pastes consisted of finely ground coral, egg shells, ginger or salt. [4] Within the last century, Alfred Fones, the founder of dental hygiene, began educating students on coronal tooth polishing ...
