Description

Toothbrush of prevention and / or treatment of dentin hypersensitivity using low level light}

The present invention relates to a toothbrush for preventing and treating dentin hypersensitivity using a low power light source, and more specifically, an LED (LED) or a laser diode installed at the bottom of the brush head of a donut-shaped toothbrush head having a circular central portion. The present invention relates to a toothbrush for preventing and treating dentin hypersensitivity using a low power light source that can treat a symptom such as dentin hypersensitivity that occurs when teeth are brushed through light irradiation from a low power light source such as a laser diode.

Existing general toothbrush is a tool for cleaning the inside of the mouth, including teeth, and is used to remove plaque and plaque that causes food debris and tooth decay remaining in the mouth after eating.

However, tooth aches, pain, and tooth shaking caused by dentin hypersensitivity, which are common in dental diseases, make it difficult to clean the inside of the mouth with a general toothbrush, especially thermal When factors, evaporation, tactile, osmotic, and chemical stimuli are applied, they become short and sharp, making it difficult to maintain normal brushing habits.

Dentin hypersensitivity is 8 times higher in ivory tubular exposure than in normal dentin (Martin Addy, UK) and twice as large as normal ivory tubular diameter, resulting in minor irritation, cold air, or irritating foods. Feeling sensitive when touched can range from mild symptoms to intense, persistent pain. Such a symptom of ache can not be expected to have a great effect even when taking painkillers or anti-inflammatory drugs, tricalcium phosphate (microcrystalline hydroxyapatite), glycerophosphate, calcium dihydrogen phosphate, calcium monohydrogen phosphate. Components such as precipitated calcium carbonate, anhydrous calcium phosphate, hydrous silicon dioxide, silica, and the like, and products such as toothpaste each containing a component such as silver nitrate have been commonly used.

The cause of dentin hypersensitivity is erosion due to bad oral hygiene habits such as gum disease caused by tartar formed due to the use of a poor quality toothbrush, damage to the surface of the gums or gum tissue due to physical impact, or improper use of the toothbrush. Each of these factors, such as erosion, abrasion, attrition, and idiopathic erosion, synergistically lead to progressive enamel and dentin deficiencies, eventually leading to exposure of the ivory tubules.

Biostimulation effect using low-power light source increases the energy level of specific elements when light is irradiated to cells or tissues, and activates cells or tissue units to promote ATP synthesis, promote cell division, promote tissue regeneration, and promote tissue metabolism. Has a physiological result. Physiological action using the biological stimulation has been studied since Mayo Clinic in 1989 using light sources such as laser, LED, and other lamps.

In their study, biostimulation results in several photochemical reactions that occur within cells, which directly affects a particular wavelength of light, and not at the laser's characteristic coherence or polarization. It is said to have a biostimulating effect by the characteristics of the.

Dentin hypersensitivity, one of the biggest causes of tooth pain, reduces the enamel and chalky thickness of teeth due to various causes and the pain caused by exposure to dentin tubules. According to the study, using a light irradiation device, the pain caused by dentin hypersensitivity of the patient was alleviated when 780 nm and 830 nm diode lasers were irradiated to the teeth at a intensity of 5 mW and 632.8 nm helium. It was reported that a neon laser with a low power of 5 mW prevented inflammation and necrosis of the dentin tubules exposed during dental treatment.

These findings are based on the current status of low level laser therapy in dentistry. part 1. soft tissue applications, L. J.
