A total of 102 asymptomatic, endodontically treated, and severely structurally compromised molars referred to a university clinic for restorative treatment were included. Teeth were randomly assigned to receive either a direct microhybrid resin composite restoration (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200951) or a lithium disilicate endocrown in conjunction with immediate dentine sealing (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200951). Restoration quality was assessed clinically using F\u00e9d\u00e9ration Dentaire International (FDI) criteria at 1\u2009week and at 3, 6, 12, and 24\u2009months. The primary outcome measure was restoration survival (FDI score \u2264\u20094). Secondary outcomes included abutment tooth survival (extraction of the tooth, regardless of the cause) and abutment tooth success (defined as the absence of tooth extraction, endodontic pathology, or the need for non\u2010surgical or surgical endodontic retreatment). Patient satisfaction was assessed using a questionnaire over the first year. Kaplan\u2013Meier estimates were used for survival analysis.
