Patients complain about teeth that are intermittently painful and hyper sensitive to cold and hot food. This pain in most cases is triggered by actions such as drinking a hot or cold beverage, eating a sweet or sour food, or dental manipulations such as touching the tooth or directing an air blast on it. The problem is known as dentinal hypersensitivity, may be a relatively simple one to treat. This is very effectively treated with dental lasers.
Dentine hypersensitivity is prevalent amongst a large portion of individuals in the age group of 30 to 40 years. The result is oral discomfort generated by pain, and may lead to nutritional deficiency due to dietary restrictions . Normally, dentine is covered by enamel or cement and does not suffer direct stimulation. Only with the exposure of the peripheral terminations of dentinal tubules is a situation of strong dentinal sensitivity manifested, termed hypersensitivity.
The most common factors responsible for dentine hypersensitivity are abrasion, caused by toothbrushing with inadequate intensity; abfraction, caused by tooth flexion associated with ill-directed occlusal forces, parafunctional habits or occlusal disequilibrium; erosion, as an effect of acids in the oral cavity; anatomic predisposition due to structural deficiency in the enamel-cement junction; cavity preparations in teeth with pulp vitality that expose the dentine; as well as improperly controlled dentinal acid conditioning.
Any treatment, which reduces the dentinal permeability, must diminish dentinal sensitivity. The effectiveness of dentine desensitization agents is directly related to their capacity to promote the sealing of the dentinal canaliculi.
With the advent of laser technology and its growing utilization in dentistry, an additional therapeutic option is available for the treatment of dentinal pain.
The laser, by interacting with the tissue, causes different tissue reactions, according to its active medium, wavelength and power density and to the optical properties of the target tissue.
The effectiveness of dentine hypersensitivity treatment with diode laser, with different wavelengths, has been reported in various clinical studies.We @ Partha Dental Have Been Using Dental Lasers for Treatment of Hypersensitivity Very Effectively.
