摘　　要：根管治疗的目的是对整个根管系统严密充填,阻止口腔微生物及其代谢产物再次进入根管,预防根尖周病变和促进根尖周病变愈合。充填后微渗漏的大小是评价根管充填质量好坏的重要指标,目前最常用的评估根管封闭能力的实验方法是染色渗漏法、微生物渗漏法以及流体滤过法。此3种实验方法各有其优缺点,且尚未标准化。Pcrfcct apical scaling is dcsirablc to prcvcnt thc rcmaining bacteria and their cndotoxins from reaching thc root apex, and to advancc thc hcaling of discasc of apical. Apical leakage is considered to bc a common cause for cndodonfic thcrapy failurc. Researchers have cvaluatcd thc quality of thc apical scaling using dyc pcnctration method, fluid filtration or transportation method, bacteria and toxin infiltration method. Thc various mcthodologics used for asscssing root canal scaling capacity arc critically analyzcd, as there arc not standaldizcd.
