My Review of Cavit G (3M Espe)
Cavit G, a temporary filling material from 3M ESPE. It belongs to the family of Cavit and Cavit W, extremely popular temporary filling materials too.
Cavit G is the cheapest amongst the 3.
I have been using Cavit G as a temporary filling material, as well as in endodontic treatment as a temporary filling material. It is soft in consistency and doesn’t stick to the filling instrument. Also, it can be packed without voids and shaped to adjust both margins and occlusion.
It has a long shelf life of over 2 years but once opened should be used as fast as possible. Care should be taken to close the lid of the jar tightly after use, otherwise the material dries up and becomes brittle. This makes it difficult to manipulate.
I usually use it for periods up to 7 days but at times patients have turned up even after 4 weeks with the filling disintegrating but still intact. I usually ask my patient to avoid chewing on the filling, as it lacks the surface hardness and wear resistance of Cavit, Cavit W or even IRM.
As Cavit G is the cheapest when compared to Cavit or Cavit W, it is readily available in the market. Hence, it can be used as temporary filling material, even in endodontic treatments, keeping the time between appointments to a minimum (less than 7 days) and asking the patient to avoid chewing on the filling.
How can we keep the product from gettin hard in the jar?
Hi.
As moisture accelerates the setting of Cavit-G, some of the product will get hard as you come to the end of the jar.
Easiest way is to tightly close the lid immediately after use.
If you have a old jar, you can scoop out a small amount for daily use into the old jar, thereby reducing the number of times you need to open the new jar.
You can also store the product in a place with minimum humidity/moisture , like, refrigerator, dehumidifier etc.
