Glass ionomer cements with milled, dry chlorhexidine hexametaphosphate filler particles to provide long-term antimicrobial properties with recharge capacity

Glass ionomer cements (GICs) are a mainstay of modern dentistry. Their uses include temporary and permanent restorations, lining and luting materials, fissure sealants and in atraumatic restorative therapy. Although GICs exhibit fluoride release, and antimicrobial effects of this can be demonstrated in vitro, the data in support of an anticariogenic effect in vivo is inconclusive [1 –3]. Nevertheless, a bioactive material that participates in ion exchange with its local environment offers an adaptable vehicle for delivery of other useful molecules to the locale of a restoration.
