INTRODUCTION
A desirable quality of any endodontic sealer is its ability to be tooth color friendly. Therefore the aim of the present study was to evaluate the tooth discoloration potential of a nano zinc oxide-eugenol (NZOE) sealer.
METHODS AND MATERIALS
In order to evaluate tooth discoloration, the pulp chamber of 60 human maxillary central and lateral incisors were filled with one of the sealers, naming AH-26 (resin-based sealer), Pulpdent sealer (ZOE-based) and a NZOE experimental sealer. Color measurements was assessed at the baseline (before placement of sealers) (T0), 24 h (T1) and 72 h (T2) h, 1-week (T3), and 1-month (T4) after the placement of sealers using the Easy Shade spectrophotometer. Data were analyzed in SPSS software using one-way ANOVA, and repeated measured ANOVA.
RESULTS
No significant differences were observed when the paired comparison test was performed (>0.05).
CONCLUSION
The tested NZOE sealer had similar tooth discoloration potential in comparison with AH-26 and ZOE sealer.
引言
任何一种根管封闭剂的理想特性是其对牙齿颜色友好的能力。因此，本研究的目的是评估一种纳米氧化锌-丁香酚（NZOE）封闭剂导致牙齿变色的可能性。
方法和材料
为了评估牙齿变色情况，60颗人类上颌中切牙和侧切牙的髓腔用以下封闭剂之一填充：AH-26（树脂基封闭剂）、Pulpdent封闭剂（丁香酚锌基）和一种NZOE实验性封闭剂。在基线（放置封闭剂前）（T0）、放置封闭剂后24小时（T1）、72小时（T2）、1周（T3）和1个月（T4）时，使用Easy Shade分光光度计评估颜色测量值。使用SPSS软件通过单因素方差分析和重复测量方差分析对数据进行分析。
结果
进行配对比较检验时未观察到显著差异（>0.05）。
结论
与AH-26和丁香酚锌封闭剂相比，所测试的NZOE封闭剂具有相似的导致牙齿变色的可能性。
