작용 기전

The main substance of our teeth is hydroxyapatite (97 % of enamel and 70 % of dentin), a calcium phosphate compound. This ingredient is safe and highly biocompatible. Nano medical hydroxyapatite (<mHAP>) particles penetrate below the surface of the enamel, providing replacement calcium and phosphate ions to areas from which minerals have dissolved, thereby remineralizing the demineralized enamel and restoring its integrity and translucent gloss.

재광화효과과 치아표면수복

• Causes remineralization comparable to a fluoride toothpaste and inhibits caries development, thus suggesting that a nano medical hydroxyapatite toothpaste can be an effective alternative to fluoride toothpastes.¹
• Remineralizes subsurface demineralized areas of tooth enamel.²
• Remineralizes tooth enamel more effectively than saliva and just as effectively as fluoride compounds. Note : fluoride promotes remineralization by saliva, where as nano medical hydroxyapatite itself remineralizes the teeth.³
• Fills and repairs minute surface defects on tooth enamel, restoring enamel to its original smoothness.⁴
• Adheres to and helps remove bacteria and biofilm, thereby protecting against tooth decay.⁵
• Removes white spots and incipient caries and restores enamel almost to its original form.⁶
• Protects against biofilm attachment and stains by reducing the crevices that harbor them.⁷

지각과민(시린이) 완화효과

Medical Hydroxyapatite nanoparticles occlude and offer a protective coating beyond comparison over exposed dentinal tubules, providing quick and effective relief from refractory tooth hypersensitivity.
Coats and fills exposed dentin and dentinal tubules protecting against dentinal hypersensitivity.¹¹
