A temporary filling is placed for two reasons:
1. Emergency client broken tooth
2. Endodontic dressing after first appointment
Emergency client broken tooth: dry the tooth (If the tooth is vital, isolate the tooth with cotton rolls and try to air dry. If the tooth is sensitive, dry the tooth with a 2×2.) Dip your Woodson #2 instrument into the Cavit G bottle and pull out plenty of Cavit G. Don’t take a saliva contaminated instrument and dip it back into the jar!
Shape the Cavit G with the Woodson and your fingers. Have the client bite down and chew around. Remove the excess. Use an explorer to make sure there’s no excess between the teeth or on the facial lingual. Warn the client not to chew on this side.
Sometimes, a stronger temporary filling will be needed (Cavit G won’t hold, or client will be gone for several weeks). Mix 1 scope of IRM powder with one drop of liquid into a very stiff paste and place the same as Cavit G.
Endodontic Temporary: The client returns several days after their first appointment. Ask the client if everything feels OK. If not, tell your doctor. If OK, place a cotton pellet in the bottle of formocresol or pt. #1 and dry it out as much as possible in a cotton 2×2. Use water and suction to thoroughly clean any food out of the tooth. Place the pellet over the canal, making sure the canal is completely covered. For molars, use two cotton pellets to make sure the canals are completely covered. Otherwise the cavity could clog a canal opening. This requires some time for the dentist to unclog. Next, place the Cavit G, using the same instructions as outlined above. Tell your client to call if s/he begins to feel a pressure build up. This means the infection is still active. If your client waits, s/he will experience pain.
