摘要： An object of the present invention is to provide a dental glass ionomer cement composition having high safety to a human body and sufficient working time, in which mechanical properties, mixing ability in hand mixing and dischargeability out of a container after mechanical kneading are simultaneously improved with satisfactory balance compared with the prior art. Disclosed is a dental glass ionomer cement composition including 0.001 to 3% by weight of (a) a polysaccharide nanofiber having an aspect ratio of 100 or more and an average fiber diameter of 100 nm or less.

摘要： The present invention provides a dental hydraulic temporary sealing material composition on which a protection of tooth substance, such as tooth substance strengthening and control of secondary dental caries, can be expected by sustained-releasing various ions including a fluoride ion, while having a high initial setting ability. More specifically, the present invention provides a dental hydraulic temporary sealing material composition comprising 65.0% to 85.0% by mass of component (1): a hydraulic inorganic powder; 10.0% to 25.0% by mass of component (2): an organic solvent; 3.0% to 15.0% by mass of component (3): a resin; and 0.01% to 10.0% by mass of component (4): an ion sustained-release glass.
