Access cavity in a crowned tooth
How do you approach the access cavity when starting root canal treatment on a tooth with an e.max crown, or when retreating a tooth with an endocrown?
Translated version of the Turkish original
Glass-ceramic restorations can be removed with an Er:YAG laser. If this is unavailable in the clinic, access can be made through the middle, as with a conventional filling. If there is leakage, however, the restoration needs to be removed completely with burs.
