General description

Effect of the chlorhexidine:hydroxypropyl-β-cyclodextrin inclusion compound on in vitro slabs of bovine dentine has been investigated[1].

Chlorhexidine is a cationic surfactant with broad-spectrum antimicrobial activity. It is used as a disinfectant in periodontal therapy and surgical scrubs.[2]

Application

Chlorhexidine, the "gold standard" in oral antiseptics, has been used to optimize novel slow release chlorhexidine coatings based on fatty acids in surgical sutures[3]. Chlorhexidine, antibacterial agent, has been used in preparaing chlorhexidine-functionalized calcium phosphate nanoparticles, useful for oral hygiene and dental treatment[4].
