Mode of Action on the Teeth


  • fill and repair areas of minute surface abrasion
  • remineralize subsurface demineralized areas (incipient caries and white spot-lesions)
  • supplement or replace inadequate or depleted tooth mineral
  • occlude exposed dentin and dentinal tubules

Sangi’s Nano-hydroxyapatite helps Dentists

  • restore mineral and surface smoothness after PMTC
  • remove white spots and surface unevenness after debonding
  • reduce sensitivity and return of discoloration after bleaching
  • provide supplementary mineral for enamel dysplasia or children’s teeth
  • protect against incipient caries, in particular root caries

Enamel Restoractive Functions Clinical use of <nHAP>

① After PMTC

fills surface fissures and restores smoothness to the enamel after scaling and use of polishing abrasives during professional mechanical tooth cleaning (PMTC)

&#9312;	After PMTC

② After Debonding

remineralizes enamel roughened or demineralized during orthodontic procedures such as cementing or debonding (removal of orthodontic brackets), restoring smoothness and reducing white spots.

&#9313;	After Debonding

③ After Bleaching

<nHAP> replenishes mineral lost during bleaching, restoring enamel density and smoothness, and protecting against sensitivity and early recurrence of stains.

Restoration of post-bleach enamel smoothness

&#9314;	After Bleaching

Protection against post-bleach stain recurrence

・Protection against post-bleach stain recurrence

Teeth either treated (a) or not treated (b) with nano <mHAP> paste after bleaching were
immersed successively in red wine, then a stain remover (PEG), for three cycles.
