Summary:  

Purpose: to test the hypothesis that the placement of a crown is associated with improved (long term) survival of root canal treated teeth, using a systematic review process of clinical studies.

N= 10 Papers.

Materials and Methods:

•MEDLINE and hand searching on campus library (from 1996 to 2006). •Third step in the selection procedure was carried out in order to aggregate survival data into a common mean outcome. 

Most highlighted Results:  

The survival rate for RCT with crowns was 81% after 10 years, while survival rate for RCT without crowns (resin composite, amalgam, cements) was 63% after 10 years.

Clinical significance: 

Restoring endodontically treated teeth with crowns will increase the survival rate of the tooth to be functioning.
