Introduction The primary goal of endodontic therapy is to achieve a three-dimensional filling of the root canal. The sealer plays a crucial role in filling the residual gaps between the gutta-percha and the canal wall, which prevents fluids and bacteria from entering the canal and causing complications. This study evaluates and compares the sealing ability of four root canal sealers to the root dentin. Methods and materials In this study, forty single-rooted mandibular premolar teeth with fully-formed apices were collected. The teeth were decoronated and instrumented. Later, the teeth were randomly divided into four groups, each comprising ten specimens, based on the sealer used for obturation. The first group was obturated with BioRoot RCS (Septodont, Septodont Holding, Paris, France), the second group with MTA-Fillapex (Angelus, Angelus Indústria de Produtos Odontológicos S/A, Brazil), the third group with EpoxySeal (Safe Endo, SafeEndo Dental India Pvt. Ltd., Gujarat, India), and the fourth group with Sealapex (Kerr, Kerr Corporation, Brea, CA). Following obturation, the teeth were sectioned vertically using a diamond disc, and the marginal adaptation of these sealers to the root dentin was assessed using scanning electron microscopy (SEM). The values were then statistically analyzed. Results EpoxySeal showed the maximum amount of marginal adaptation (5.22±0.47), followed by BioRoot RCS (5.48±0.58) and MTA-Fillapex (8.24±0.74), and the least amount of marginal adaptation was shown by Sealapex (11.64±1.35). Based on the analysis of variance (ANOVA), a statistically significant difference (p≤0.001) was observed. According to Tukey's post hoc test, the mean difference between all groups showed statistical significance (p≤0.05) except between BioRoot RCS and EpoxySeal. Conclusion Within the limitations of this in vitro study, it is concluded that EpoxySeal and BioRoot RCS exhibited superior marginal adaptation to the root dentin. BioRoot RCS can be recommended as a sealer of choice owing to its additional properties, such as antimicrobial and hydrophilic affinity during setting.
引言 牙髓治疗的主要目标是实现根管的三维充填。封闭剂在充填牙胶尖与根管壁之间的残余间隙中起着关键作用，这可防止液体和细菌进入根管并引发并发症。本研究评估并比较了四种根管封闭剂对牙根牙本质的封闭能力。
方法和材料 在本研究中，收集了40颗根尖完全形成的单根下颌前磨牙。对牙齿进行去冠和预备。随后，根据用于充填的封闭剂，将牙齿随机分为四组，每组包含10个标本。第一组用BioRoot RCS（法国赛特多公司，赛特多控股，巴黎）进行充填，第二组用MTA-Fillapex（巴西安吉利斯公司，安吉利斯口腔产品工业有限公司），第三组用EpoxySeal（印度古吉拉特邦Safe Endo牙科印度私人有限公司，Safe Endo），第四组用Sealapex（美国加利福尼亚州布雷亚市克尔公司）。充填后，用金刚石圆盘将牙齿垂直切片，并用扫描电子显微镜（SEM）评估这些封闭剂与牙根牙本质的边缘适应性。然后对这些值进行统计分析。
结果 EpoxySeal显示出最大的边缘适应性（5.22±0.47），其次是BioRoot RCS（5.48±0.58）和MTA-Fillapex（8.24±0.74），而Sealapex显示出的边缘适应性最小（11.64±1.35）。基于方差分析（ANOVA），观察到具有统计学意义的差异（p≤0.001）。根据Tukey事后检验，除BioRoot RCS和EpoxySeal之间外，所有组之间的平均差异均具有统计学意义（p≤0.05）。
结论 在本体外研究的局限性范围内，得出的结论是EpoxySeal和BioRoot RCS对牙根牙本质表现出优异的边缘适应性。由于BioRoot RCS在凝固过程中具有抗菌和亲水亲和力等其他特性，因此可推荐其作为首选封闭剂。
