Tools of the trade: Fuji 7


Fuji7by Dr Peter Buys, Lisarow Dental Care, Lisarow, NSW


Fuji 7 is an active GIC filling material developed by GC Dental in Japan. It works particularly well for root surface caries as it has a high fluoride release and has recently added Recaldent to its composition.


What’s good about it

It releases significant amounts of fluoride and helps to seal and protect the tooth. When I first started using it, I thought it was more of a temporary filling. However, several years after placing it in people who I expected to lose a tooth, the results were fantastic. The Fuji 7 and the tooth were still in position when I had expected either the material or tooth to have failed.

Sometimes I will treat a patient who is medically compromised or elderly and can barely keep their mouth open. Fuji 7 works really well in these cases as an intermediate filling material or even a palliative filling. It’s ideal when you have limited time and I often use it with elderly patients and children.

Ideally, you would anesthetise and remove most of the caries but where that’s not completely possible, this is an efficient alternative. It doesn’t destroy caries but it provides a great seal and deactivates it to a degree I have not experienced with other GIC materials.

It’s under-utilised by dentists because of a perception that it’s not very strong. It makes up for that by flowing into the space and sticking really well. It has exceeded what I expected it to do.


What’s not so good

It can’t be used on the top of the tooth or near the front of the mouth because of its pink colour. The manufacturer has addressed this concern by producing a white version but I find that doesn’t work quite as well—it has the typical structural limitations of most GICs. It would be an improvement if it set faster and had better strength, but there’s reasons for that.
