Background

The restoration of endodontically treated teeth that have had a significant portion of their coronal material destroyed is challenging. These teeth are weak as a result of the removal of the pulp and surrounding dentin, so intraradicular posts with or without core materials may be needed to strengthen the restoration. However, the use of posts involves the removal of additional sound tissue, which further compromises tooth performance. An alternative to consider is endocrown restorations. These

Methods

The literature search screened the PubMed (Medline), Lilacs, Ibecs, Web of Science, BBO, Scielo, and Scopus databases. Eight studies were identified that met the inclusion criteria; 3 were clinical trials and 5 were in vitro studies. The 5 in vitro studies were assessed in the meta-analysis.

Results

The 3 clinical trials (published between 1999 and 2014) evaluated a total of 55 teeth and showed success rates for endocrowns between 94% and 100%, with follow-up periods from 6 to 36 months. Two endocrown failures occurred, the result of secondary caries.

The 5 in vitro studies (published between 2008 and 2015) assessed a total of 102 teeth, with sample sizes in each study between 20 and 48 teeth. The focus was the fracture strength of endocrowns, along with failure modes, marginal continuity,

Discussion

Compared to conventional restorations, endocrowns appear to perform better. The conventional restorations tested included intraradicular posts, direct composite resin, and inlay/onlay methods. The small sample sizes and lack of information about endocrown use in anterior teeth are limitations the clinician should take into account when making clinical decisions.

Clinical Significance

The use of endocrowns rather than conventional restorations for endodontically compromised teeth appears to offer
