Effect of zirconia tube reinforcement on fracture resistance and microleakage of endodontically treated premolars with flared root canals under cyclic loading

Key Points

• The research aims to evaluate the effects of zirconia tube reinforcement on fracture resistance and microleakage in endodontically treated premolars with flared root canals.
• Conducted experiments on endodontically treated premolars with flared root canals
• Applied zirconia tube reinforcement
• Tested fracture resistance under cyclic loading
• Assessed microleakage levels
• Zirconia tubes significantly enhanced fracture resistance in treated premolars
• There was a notable reduction in microleakage in samples reinforced with zirconia tubes
