目的:本系统综述的目的是评估不完整套圈对牙髓治疗(ETT)的骨折的影响。
方法:诸如\"不完整的套圈,\"\"套圈,\"\"套圈效应,\"\"残留牙本质,\"\"剩余的牙本质,“或”剩余的冠状牙本质“用于搜索,并且仅包括研究套圈对天然牙齿的不完全影响的体外研究。
方法:PubMed,Medline,Embase,科克伦图书馆,和科学直接数据库,和手动搜索。
方法:搜索策略产生了1633个命中,共包括19项与不完全套圈对ETT的影响密切相关的体外研究。
结论:不完整套圈的存在可能显着增加修复的ETT的抗断裂性,与没有套圈的恢复ETT相比。不完整套圈的剩余轴向壁的数量可能对断裂阻力和断裂模式有影响。不完整套圈的剩余轴向壁的位置可能会影响抗断裂性,但不会影响断裂模式。
结论:有限的数据表明,不完整套圈的存在对修复的ETT的抗骨折性有积极的影响。当不存在完整的套圈时,不完整的套圈可以是恢复ETT的替代方案。然而,仍需要进一步的高质量研究来提供更有力的证据,并考虑潜在的混杂因素.
The purpose of this systematic review was to assess the impact of the incomplete ferrule on the fracture of endodontically treated teeth (ETT).
The keywords such as \"incomplete ferrule,\" \"ferrule,\" \"ferrule effect,\" \"residual dentin,\" \"remaining dentin,\" or \"remaining coronal dentin\" were used for searching, and only in vitro studies investigating the incomplete ferrule effect on natural teeth were included.
PubMed, Medline, Embase, Cochrane Library, and Science Direct databases, and manual-searching.
The search strategy yielded 1633 hits, and a total of 19 in vitro studies closely related to the effect of incomplete ferrule on ETT were included.
The presence of an incomplete ferrule may significantly increase the fracture resistance of restored ETT, compared with restored ETT without ferrule. The number of residual axial walls of the incomplete ferrule may have an impact on the fracture resistance and fracture mode. The location of residual axial walls of the incomplete ferrule may affect the fracture resistance but not the fracture mode.
Limited data suggest that the presence of incomplete ferrule has a positive effect on the fracture resistance of restored ETT. An incomplete ferrule can be an alternative for restoring ETT when a complete ferrule is not present. Nevertheless, further high-quality studies are still needed to offer more robust evidence and to take potential confounding factors into account.
