The invention relates to a method of preparing an implant material in which particles of a bioactive ceramic biomaterial, such as apatite, of a size of at least 200 µm are mixed with water and a water-soluble hydrocolloid. The invention also relates to a two-component kitfor preparing the implant material.
摘要:
A composition for treating dental infections, e.g. dental caries caused by Strep. mutans, comprises a varnish containing a dentally acceptable antimicrobial agent such as chlorhexidine acetate and benzoin gum in an orally acceptable liquid. The composition can be painted on teeth, allowed to dry thereon to give a transparent, translucent or tooth colored film which is effectively invisible but provides sustained release of the antimicrobial agent to the site of infection over a period of at least four days. The film can be removed at will, e.g. by application of the liquid varnish base.
