Fuji VII is ideal for this application where it can be used as a temporary seal between endodontic treatments. The ion exchange adhesion will ensure an effective coronal seal which is proof against microleakage and possible further contamination of the operative area. The contrasting pink shade aids fast removal when the next stage of treatment is undertaken and, if it is desirable to reseal the canal before final restoration, a new increment of GC Fuji VII will strongly adhere to the original glass ionomer material.
