Abstract

OBJECTIVE

The purpose of this study was to evaluate the radiopacity of a new root canal sealer, Epiphany, relative to 3 other root canal sealing materials, AH 26, Sealapex, and Ketac-Endo.

STUDY DESIGN

Radiographs were taken of 1-mm-thick specimens of 4 root canal sealers and dentine slides, as well as a range of aluminum thicknesses, by using a step-wedge. The radiographic density of each specimen was measured and correlated with the equivalent thickness of aluminum.

RESULTS

All sealers were found to be more radiopaque than dentine (1.05 +/- 0.2-mm aluminum) and to possess radiopacity of greater than 3-mm aluminum. The radiopacity values reported in this study were 11.27 +/- 0.18-mm, 10.88 +/- 0.16-mm, 10.35 +/- 0.15-mm, and 9.78 +/- 0.21-mm aluminum for Sealapex, Ketac-Endo, Epiphany, and AH 26, respectively, which were significantly different from each other (P < .01).

CONCLUSION

Radiopacity measurements for Epiphany, Ketac-Endo, Sealapex, and AH 26 exceeded the minimum standard for root canal sealers. Epiphany has higher radiopacity than dentine. Therefore, this sealer is suitable for endodontic usage in terms of radiographic assessment.

摘要

目的

本研究旨在评估一种新型根管封闭剂Epiphany相对于其他三种根管封闭材料AH 26、Sealapex和Ketac-Endo的射线不透性。

研究设计

使用阶梯楔形板对4种根管封闭剂和牙本质玻片的1毫米厚样本以及一系列不同厚度的铝片进行射线照相。测量每个样本的射线照相密度，并将其与铝的等效厚度相关联。

结果

发现所有封闭剂的射线不透性均高于牙本质（相当于1.05±0.2毫米厚的铝），且射线不透性大于3毫米厚的铝。本研究报告的射线不透性值分别为：Sealapex为11.27±0.18毫米铝、Ketac-Endo为10.88±0.16毫米铝、Epiphany为10.35±0.15毫米铝、AH 26为9.78±0.21毫米铝，它们之间存在显著差异（P<.01）。
