Demonstrates improved fracture resistance and reduced microleakage in endodontically treated premolars, suggesting zirconia tubes as a reliable reinforcement option.
Zirconia tubes enhanced fracture resistance and reduced microleakage under cyclic loading in endodontically treated premolars. Foundation restorations using zirconia tubes may be a reliable reinforcement option for structurally weakened roots. Further clinical and long-term studies are required to confirm these findings.
