摘　　要：桩核冠修复是临床大面积牙体缺损的主要修复方法,桩腔预备是修复的第一步,预备过程中保持剩余根管充填物的完整性对于根尖封闭有重要意义。目前的研究表明:桩腔预备对根尖封闭性的影响与桩腔预备时机、剩余根管充填物长度和桩腔预备技术等有关。微渗漏量作为评价根尖封闭效果的重要指标,检测方法种类繁多,包括染色法、流体滤过(传输)系统、细菌(毒素)检测法、葡萄糖定量检测法等,且各有利弊。本文就桩腔预备对根尖封闭性的影响及检测方法的研究进展作一综述。Post and core restoration has been widely used in clinic for a large amount loss of teeth.As the first step of this restoration,post space preparation plays an important role in the apical sealing ability.Immediate or delayed preparation,the amount of root canal filling remaining,gutta-percha removal techniques and obturation techniques used have been the subjects of investigation on it.Microleakage is considered to be a key indicator in assessing the apical ability.Several methods for testing apical leakage have also been introduced,such as using dyes,fluid filtration or transport methodology,bacteria and toxin infiltration method.General studies regarding the apical sealing of post space preparation and methodologies for assessment will be discussed in this review.
