Abstract

Objectives: The purpose of this study was to compare the sealing ability of different glass ionomer cements (GIC) as root-end filling (RF) materials. Materials and Methods: One-hundred and eleven extracted human canines were cleaned and prepared using a rotary nickel titanium files with crown-down technique. All the teeth were filled with gutta-percha and then the apical third of each root was resected perpendicularly to the long axis direction. After, root-end cavity was prepared using a round bur. The specimens were randomly divided into 7 groups of 15 samples, filled with one of the test materials (Ionofil, Ketac Molar Quick Aplicap, Argion Molar AC, Photac Fil Quick Aplicap, Fuji II LC Capsule, Dyract Extra, Glasiosite Caps) and were stored at 37°C and 100% humidity for 7 days. 1-week later, apical parts of roots of 10 ± 0.05 mm were attached to the computerized fluid filtration device. The data obtained were analyzed using an ANOVA and post hoc Tukey′s tests (P ≤ 0.05). Results: Statistical analysis indicated that RF with Argion molar AC (reinforced GIC) had the least micro-leakage of all and whereas Ketac Molar Quick Aplicap (conventional GIC) showed highest apical leakage than the other groups. Conclusion: This present study has shown that none of GICs, which used as a RF material unable to prevent apical leakage exactly and Argion Molar AC is used as a RF material among current GICs better than others.
不同玻璃离子水门合剂作为根端充填材料的密封性能比较
目的:本研究的目的是比较不同玻璃离子水门栓(GIC)作为根端充填(RF)材料的密封能力。材料与方法:采用镍钛旋转锉冠冠法对提取的111只人犬进行清洗和制备。所有的牙齿都用杜仲胶填充,然后垂直于长轴方向切除每根根尖的三分之一。然后,用圆钻制备根端腔。样品随机分为7组,每组15个样品,分别填充一种测试材料(Ionofil、Ketac Molar Quick appap、Argion Molar AC、Photac Fil Quick appap、Fuji II LC Capsule、Dyract Extra、Glasiosite Caps),在37℃、100%湿度下保存7天。1周后,10±0.05 mm的根尖部附着于计算机流体过滤装置上。所得资料采用方差分析和事后Tukey检验进行分析(P≤0.05)。结果:经统计学分析,Argion磨牙AC(强化型GIC)组的牙尖外露最少,而Ketac磨牙Quick app(常规型GIC)组的牙尖外露最多。结论:本研究表明,作为射频材料的GICs中,没有一种不能准确预防根尖泄漏,而Argion磨牙AC作为射频材料在目前的GICs中表现较好。
