Fuji II LC

Had a go with Fuji II LC the other day on a 45DB. It's a pretty weird thing... RMGIC so it partially sets as a GIC and must be light cured as a resin. This 45 in particular had terrible access. the adjacent 46 was absent and the caries was on the distal surface meaning I had a choice of either performing a traditional box preparation or approaching from the distal surface in the gap between the 45 and 47. I chose the latter and visibility was terrible! after quite a bit of guesswork, I prepped the cavity which extended buccally under a class V composite. I removed this and cleaned the margins of deminned enamel. The demonstrated, a fill in Dr. L suggested I somehow incorporate the RMGIC in the restoration as it had potential to be aesthetic. She suggested RMGIC on the buccal aspect and FujiIX on the distal. She suggested the use of Hawekerr clear matricies? It had a clear triangular form with a handle to hold with tweezers. The idea was to fill the cavity from the buccal and when the matrix compressed the material it would flow to the distal and we would fill the rest with fuji 9. However when the material flowed it filled quite a bit and only a small defect on the distal. I trimmed the excess off the margins and just filled in the defect with a new mix of fuji II and a flat plastic after reconditioning the fuji surface.

When trimming i realised that slow speed discs and burs tended to dry the material out due to the lack of water spray so Dr. L suggested I apply some optibond over it to avoid short term dessication of the material before it has had a chance to mature. Further questions must be asked if it is possible to coat instruments in bond to avoid sticking of the RMGIC like with resin materials
