Abstract: BACKGROUND: The use of fiber post to repair the endodontically treated non-carious cervical lesions teeth can change the stress distribution of the tooth and significantly reduce the risk of fracture of the affected tooth. However, the mechanical mechanism of fiber posts improving tooth fracture resistance and the optimal crown restoration for endodontically treated non-carious cervical lesions teeth are still debated.
OBJECTIVE: To review the stress distribution pattern after restoration of endodontically treated non-carious cervical lesions teeth with fiber posts, the fracture resistance and fracture pattern under various stress states, and the latest research progress on fiber posts combined with different crown restorations. 
METHODS: The computerized search was applied in PubMed and CNKI to retrieve articles published from September 2008 to September 2023 with Chinese and English search terms “non-carious cervical lesions, endodontically treated teeth restoration, endodontically treated teeth stress distribution.” Finally, 56 articles were included for analysis.
RESULTS AND CONCLUSION: The application of fiber post restoration for endodontically treated non-carious cervical lesion teeth can partially improve the cervical stress of the tooth without increasing the risk of vertical root fracture, can lead to a more consistent distribution of stress and enhance the tooth’s ability to withstand fractures. Non-carious cervical lesion teeth with fiber posts that fracture would show favorable, restorable, or repairable fracture patterns. Fiber posts in combination with porcelain veneers or veneer-type inlays may become a more desirable minimally invasive restoration for repairing endodontically treated non-carious cervical lesion teeth.
