Description
Technical field
The present invention relates to a kind of lubricant for root canal therapy and preparation method thereof.
Background technology
Pulpitis, pulp necrosis, periapical inflammation are the higher mouth diseases of incidence, are controlled for such illness is most effective
More means are exactly root canal.Particularly with decoronated teeth tooth, reparation section needs to carry out post crown restoration, and root canal therapy is only
One therapy that can be selected.Root canal is that the method by debridement, mechanically and chemically is thoroughly removed and infected in root pipe
Source, since root canal system is sufficiently complex, including collateral pulp canal, Accessory canals etc., it merely can not thorough cleaning root by mechanical preparation
Bacterium in pipe.Flushing liquor ingredient clinically mainly is sodium hypochlorite at present, and sodium hypochlorite can dissolve in root pipe in smear layer
Organic organization, smear layer can be made thinning, loose and be more easy to be rinsed liquid and wash away, but be mainly inorganic matter due to staining composition of layer
Matter, therefore exclusive use sodium hypochlorite cannot completely remove smear layer, it is necessary to it is used cooperatively the root pipe containing special chemical ingredient
Lubricant is removed.
