Overview
Brief Summary
Restoration of endodontically treated teeth requires a means to protect the cusps from the wedging forces of occlusion. When there is extensive loss of tooth structure, cuspal coverage is warranted. Usually this is in the form of indirect restoration. Traditionally, full coverage crowns have been used which would require further removal of sound tooth structure. Recently, adhesive alternatives have been introduced which allow for conservation of tooth structure.
Different materials can be used for this purpose. The evidence on the long-term survival of these materials is scarce. This study aims to investigate the short and medium-long term survival rate of these prostheses.

Eligibility Criteria
Inclusion Criteria
- •Root canal treated molars with significant loss of tooth structure
- •Supra-gingival margins
- •Teeth scheduled for cuspal-covering indirect restorations
Exclusion Criteria
- •Teeth with extensive cracks or fractures
- •Teeth with deep subgingival margins
- •Non-functional teeth (no opposing dentition)
- •Teeth with advanced periodontitis
Outcomes
Primary Outcomes
Survival of Dental Prosthesis
Time Frame: 24 months
The endocrowns (the dental prosthesis studied) were assessed after 24 months. Those that were functional and without any symptoms were considered surviving.
