[Validity of root canal therapy before prosthetic treatment with metal ceramic crowns].

Unlabelled: Root canal therapy before prosthetic treatment with porcelain fused metal crowns is necessary only in case of special indications. Purpose of our investigation was to identify prevalence and validity of root canal therapy before prosthetic treatment. 873 DCC (Dental Clinical Charts) had been examined retrospective to determine the quantity of root canal treated teeth, non involved teeth, and teeth treated exclusively for prosthetic treatment.

Results: 1377 non involved teeth had root canal therapy before prosthetic treatment (84.22% of 1635 investigated teeth), among them 1371 (83.85%) had no specific indications for endodontic therapy.
