Abstract

AIM

To compare and evaluate the sealing ability of four different commercially available sealers to provide seal against the dye penetration test using a stereomicroscope-an in-vitro study.

MATERIAL/METHOD: 80 extracted single rooted mandibular premolar with single canal were used in this study. The samples were divided in 4 groups (20 in each) based on sealer. Group I (Diaproseal), Group II (apexit Plus), Group III (MTA Fillapex) and Group IV (Bio-C). The samples were analyzed using a stereomicroscope and data analysis was done with one-way Anova And post hoc Tukey's test.

RESULT

The mean dye penetration score was 1.2400 ± 0.778 mm for Group I. 2.6000 ± 0.897 mm for Group II, 4.2000 ± 0.923 mm for Group III and 4.225 ± 2.055 mm for Group IV. One-way Anova analysis shows that intergroup comparison was statistically significant between the four groups. The post hoc Tukey's test reveals that the difference was statistically non-significant between group III and group IV.

CONCLUSION

It was concluded that between the four groups the Group I (Diaproseal) showed the least dye penetration followed by Group II (Apexit Pus), Group III (MTA Fillapex) and then Group IV (Bio-C), where there was no significant difference between the Group III (MTA Fillapex) and Group IV (Bio-C).

摘要

目的

通过立体显微镜下的染料渗透试验比较和评估四种不同市售封闭剂的封闭能力——一项体外研究。

材料/方法：本研究共使用 80 颗下颌单根前磨牙，均为单根管。根据封闭剂的不同，将样本分为 4 组（每组 20 个）。第 I 组（Diaproseal）、第 II 组（apexit Plus）、第 III 组（MTA Fillapex）和第 IV 组（Bio-C）。使用立体显微镜对样本进行分析，并采用单因素方差分析和事后 Tukey 检验进行数据分析。

结果

第 I 组的平均染料渗透评分 1.2400 ± 0.778mm；第 II 组为 2.6000 ± 0.897mm；第 III 组为 4.2000 ± 0.923mm；第 IV 组为 4.225 ± 2.055mm。单因素方差分析显示，四组间的组间比较具有统计学意义。事后 Tukey 检验显示，第 III 组和第 IV 组之间的差异无统计学意义。
