Using bulkEZ PLUS with Prelude ONE

1. Shake the Prelude ONE bottle before each use. It is a lightly filled bonding agent and like all others of this type, the filler requires dispersing.
2. Prelude ONE is a great universal bond and can be used with total etch (etch and rinse), self etch and selective etch. It is a very advanced bond with the added advantage of a very thin film thickness.
3. Apply a thin layer and gently apply air. All the steps (etch-optional, application, light cure) are 10 seconds each.
4. While bulkEZ PLUS will give catalyst to Prelude ONE, Prelude ONE still needs to be light cured. bulkEZ PLUS will complete the cure of any areas that the light does not fully reach.
5. The first time the a bulkEZ PLUS syringe is used, like other dual syringe products, it does need to be bled before the tip is fitted until material is at the end of both tubes. Then ensure that the cap of the tip is properly aligned (notches on the cap and the syringe) before twisting on. It is possible to force the tip on incorrectly. If the bleeding is not carried out the first part of the application may not properly set. As this was the first time that you have used the material, this could be the cause.
6. Each time a new tip is used express a small amount onto a pad to ensure that the materials begin their mix within the tip. Keep the tip in place until just before the next use. Do not replace the cap as this can cause cross contamination of the catalyst/base.
7. Place the material from the base of the cavity up, filling the cavity. This should be done as quickly as possible.
8. Any adaptation of the material at the gel stage should be carried out moving from the material to the tooth so as not to drag material away from the margins.
9. DO NOT LIGHT CURE bulkEZ PLUS AT ALL UNTIL FULLY SET. This will cause shrinkage towards the light just like any other composite that has been deeply filled in one go. Any shrinkage that occurs due to the dual cure is towards the tooth, hence the absence of microleakage.
10. Only when fully set can a light be applied to cure the few micron thick air inhibited layer. There is no need for this if you are removing this during occlusal adjustment or applying a conventional composite on the surface to ‘beautify’ the appearance. Air blocking materials such as glycerine can also be used.
