目的 研究铸造镍铬合金桩核、黏接银汞桩核、传统银汞桩核和纤维树脂桩核的冠向微渗漏情况,为临床桩核的选择提供依据.方法 选择60颗新拔除的人上颌磨牙,随机分为6组,其中4组分别制作铸造镍铬合金桩核、黏接银汞桩核、传统银汞桩核和纤维树脂桩核,另2组分别为阳性和阴性对照,然后浸入印度墨水中1周,评价不同桩核的冠向微渗漏情况.结果 4个实验组微渗漏明显小于阳性对照组(P ＜ 0.05);纤维树脂桩核组和黏接银汞桩核组微渗漏明显小于传统银汞桩核组和铸造镍铬合金桩核组(P ＜ 0.05).结论 各种桩核修复都可在一定程度上减小微渗漏,其中黏接银汞桩核和纤维树脂桩核修复更为有效.
目的 研究鑄造鎳鉻閤金樁覈、黏接銀汞樁覈、傳統銀汞樁覈和纖維樹脂樁覈的冠嚮微滲漏情況,為臨床樁覈的選擇提供依據.方法 選擇60顆新拔除的人上頜磨牙,隨機分為6組,其中4組分彆製作鑄造鎳鉻閤金樁覈、黏接銀汞樁覈、傳統銀汞樁覈和纖維樹脂樁覈,另2組分彆為暘性和陰性對照,然後浸入印度墨水中1週,評價不同樁覈的冠嚮微滲漏情況.結果 4箇實驗組微滲漏明顯小于暘性對照組(P ＜ 0.05);纖維樹脂樁覈組和黏接銀汞樁覈組微滲漏明顯小于傳統銀汞樁覈組和鑄造鎳鉻閤金樁覈組(P ＜ 0.05).結論 各種樁覈脩複都可在一定程度上減小微滲漏,其中黏接銀汞樁覈和纖維樹脂樁覈脩複更為有效.

Objective The aim of this study was to compare the coronal microleakage of casting nickel chromium alloy post and cores, bonded amalgam cores, conventional amalgam cores and fiber post reinforced composite resin cores on endodotically treated molars. Methods Sixty extracted human maxillary molars were endodontically treated and assigned to six groups randomly. Four groups were prepared for casting nickel chromium alloy post and cores, bonded amalgam cores, conventional amalgam cores and fiber post reinforced composite resin cores respectively. The other two groups served as positive control and negative control. The teeth were stored in India ink for 1 week. The coronal microleakage of ink penetration was assessed with a coded scoring system. Results The four experimental groups showed significantly less microleakage than the positive control (P ＜ 0.05). The bonded amalgam cores and fiber post reinforced composite resin cores demonstrated significantly less microleakage than the casting nickel chromium alloy and conventional amalgam cores (P ＜ 0.05). Conclusion All kinds of post and cores can reduce the microleakage of endodotically treated molars. Bonded amalgam and fiber post reinforced composite resin core are more preferable.
