Dentin hypersensitivity seems to be a common problem and still remains an enigma in diagnosis. The discomfort that arises as a result of dentin hypersensitivity is said to greatly affect the quality of life of the patients. On reviewing the literature, the prevalence of dentin hypersensitivity can range anywhere from 4.8% to 62.3%. The success of treating dentine hypersensitivity mainly depends on the long-term efficiency of treatment modalities. The treatment modalities include the use of desensitizing chemical agents and LASER.
To the best of our knowledge, till date, based on the evidence from clinical trial, the long-term prognosis of desensitizing toothpaste has not yet been clearly identified. Most of the clinical trial evaluated the prognosis only till the period of 12 weeks; hence, more trial is necessary. Moreover, some clinical trials were reported with publication bias. Many company-sponsored clinical trials reported the results which favor the benefit of the company, but the adverse outcome was not addressed., In the recent years, LASER seems to provide promising results. The mechanism of action differs with the type of LASER. Low-power LASER has a biomodulatory effect; cellular metabolic activity of odontoblast gets increased thereby blocking the dentinal tubules. Whereas, high-power LASER increases the surface temperature and promotes recrystallization of dentinal surface that results in blockade of dentinal tubules. The previous report stated that adhesives like cyanoacrylate have higher efficiency than LASER. Furthermore, regenerative procedures such as guided tissue regeneration with a three-layered membrane lead to successful results in the management of hypersensitivity. 8% nanocarbonated hydroxyapatite collagen/poly (lactic-co-glycolic acid) (nCHAC/PLGA) forms the inner porous membrane, 4% nCHAC/PLGA forms the middle layer, and PLGA forms nonporous outer membrane. When placed, it forms highly biocompatible membrane which helps in tissue regeneration.
In the recent years, dynamic biological agents, namely stem cells such as stem cells from apical papilla, dental pulp stem cells (DPSC), and scaffold attribute to de novo regeneration of dentin. However, the challenge is that the functional regeneration of dentin depends on enamel regeneration. The availability of Dental Epithelial Stem Cells (DESC) that is responsible for enamel regeneration is very scarce. Porcine epithelial rests of Malassez when cultured with DPSC can differentiate into enamel. The challenge in de novo enamel regeneration is time frame. It requires many years to form enamel which is not compatible with our clinical needs, and even if there is mild disturbance during the process, it may lead to defective enamel formation.
However, lot of research is still ongoing in achieving the ultimate goal in the treatment of dentin hypersensitivity which is the permanent relief of discomfort thereby improving the patients' quality of life.
