Overview

Randomized trial compares clinical performance of two crown types in compromised molars, suggesting both are viable options.

Key Points

  • To compare the clinical performance of direct resin composite and lithium disilicate endocrowns in endodontically treated molars over 2 years.
  • Randomized controlled superiority trial (ClinicalTrials.gov: NCT06934460)
  • Included 102 asymptomatic, endodontically treated molars randomly assigned to two restoration types
  • Clinical assessment of restoration quality and patient satisfaction via standardized scores at regular intervals.
  • Cumulative restoration survival rates: 98.0% for resin composite and 100.0% for lithium disilicate (p = 0.32)
  • Tooth survival was 100.0% in both groups
  • Indirect endocrowns showed superior surface quality and resisted wear better after 24 months, though patient satisfaction was similar.
