Abstract

BACKGROUND

The purpose of this study was to assess the push-out bond strength of calcium-silicate and silicone based root canal sealers in bulk and with main cone.

METHODS

Roots (n=48) randomly divided into 4 groups (n=12) according to the obturation protocol; (1) iRoot SP in bulk; (2) iRoot SP with gutta-percha; (3) GuttaFlow Bioseal in bulk; (4) GuttaFlow Bioseal with gutta-percha. Six horizontal sections were obtained from each root (n=72). Effect of sealers on bond strength was statistically significant (<0.05).

RESULTS

Highest mean value was obtained in iRoot-Bulk group and lowest in GuttaFlow Bioseal-GP group. Both iRoot SP groups had significantly higher bond strength values than both GuttaFlow Bioseal groups (<0.05). There was no significant difference between iRoot-GP and iRoot-Bulk groups (=0.603) also GuttaFlow Bioseal-GP and GuttaFlow Bioseal-Bulk groups (=0.684).

CONCLUSION

Based on findings, using calcium silicate-based sealer in bulk can be also suitable in clinical practice.

摘要

背景

本研究的目的是评估硅酸钙基和硅酮基根管封闭剂在整体以及与主尖锉联合使用时的推出粘结强度。

方法

根据充填方案将48颗牙根随机分为4组（每组12颗）；（1）整体使用iRoot SP；（2）iRoot SP与牙胶联合使用；（3）整体使用GuttaFlow Bioseal；（4）GuttaFlow Bioseal与牙胶联合使用。从每颗牙根获取6个水平切片（共72个）。封闭剂对粘结强度的影响具有统计学意义（<0.05）。

结果

iRoot-整体组获得的平均值最高，GuttaFlow Bioseal-牙胶组最低。两个iRoot SP组的粘结强度值均显著高于两个GuttaFlow Bioseal组（<0.05）。iRoot-牙胶组和iRoot-整体组之间无显著差异（=0.603），GuttaFlow Bioseal-牙胶组和GuttaFlow Bioseal-整体组之间也无显著差异（=0.684）。
