Dentin hypersensitivity is a relatively common condition. [4] [3] Due to differences in populations studied and methods of detection, the reported incidence ranges from 4-74%. [3] Dentists may under-report dentin hypersensitivity due to difficulty in diagnosing and managing the condition. [4]
Epidemiological surveys have shown that dentine hypersensitivity arises when the dentinal tubules are both exposed and patent. It was proposed that if the hydrodynamic fluid flow was responsible for hypersensitivity, then there must be higher numbers of dentinal tubules exposed at the surface of the root and patent to the dental pulp.
The pulp of the tooth remains normal and healthy in dentin hypersensitivity. [10]: 510 Many topical treatments for dentin hypersensitivity are available, including desensitizing toothpastes and protective varnishes that coat the exposed dentin surface. [16] Treatment of the root cause is critical, as topical measures are typically short lasting.
Sensodyne is a brand of toothpaste that was first sold by Block Drug, a Brooklyn, New York-based company established in 1907 by pharmacist Alexander Block. [1]By 1925, manufacturing dental care products had become the company's focus.
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.

Cross-section of a tooth. B is dentin. Dentin (/ ˈ d ɛ n t ɪ n / DEN-tin) (American English) or dentine (/ ˈ d ɛ n ˌ t iː n / DEN-teen or / ˌ d ɛ n ˈ t iː n / DEN-TEEN) (British English) (Latin: substantia eburnea) is a calcified tissue of the body and, along with enamel, cementum, and pulp, is one of the four major components of teeth.
Furthermore, numerous clinical trials have shown gluconate chelated stannous fluoride toothpastes possess superior protection against dental erosion and dentine hypersensitivity compared to other fluoride-containing and fluoride-free toothpastes. [32] Much of the toothpaste sold in the United States has 1,000 to 1,100 parts per million fluoride.
