Key Points

Microleakage levels in the lithium disilicate group were significantly lower than those in the PEEK group, indicating a better seal.
The microtensile bond strength of lithium disilicate was 7.11 MPa, compared to 3.31 MPa for PEEK, showing superior adhesion.
The study utilized thermal cycling and dye penetration methods to evaluate microleakage and bonding strength in endocrowns.
Findings suggest choosing lithium disilicate over PEEK to minimize microleakage in endodontic restorations.
