Abstract

INTRODUCTION

Disinfection of the root canal system is crucial for a successful endodontic treatment. Several factors influence the performance of effective irrigation. Diverse irrigating substances have been used but none has proved to completely penetrate the root canal system. HybenX dries due to its hygroscopic properties; therefore, it is effective in the treatment of -related diseases. This investigation aimed to estimate HybenX's degree of penetration into the dentinal tubules of upper first premolars.

MATERIALS AND METHODS

Experimental intervention where 30 extracted maxillary premolars were evaluated to determine HybenX's degree of penetration and 5% sodium hypochlorite in the dentinal tubules using three different irrigation techniques (passive ultrasonic irrigation, dynamic manual irrigation and conventional single jet irrigation technique). After preparation, the root canals were irrigated with fluorescent rhodamine 6G; then 500-micrometer sections were made to be analyzed under a fluorescence microscope. Measurements were made in micrometer in ZEN software to determine the penetration degree of each substance in the different root thirds.

RESULTS

In the apical third, significant differences between the 3 irrigation techniques were found (<0.05), similarly, for the middle and cervical thirds. Significant statistical differences between the HybenX and sodium hypochlorite were found at the cervical and middle levels when using the conventional Monoject irrigation and passive ultrasonic irrigation techniques. As for the apical level, differences were found between the passive ultrasonic irrigation techniques and the dynamic manual irrigation technique.

CONCLUSIONS

Based on this study, HybenX proved to highly penetrate into the dentinal tubules, especially when using the passive ultrasonic irrigation technique. HybenX may be a useful option for root canal irrigation in endodontics.

摘要

引言

根管系统的消毒对于成功的牙髓治疗至关重要。有几个因素会影响有效冲洗的效果。人们使用了多种冲洗物质,但没有一种被证明能完全穿透根管系统。HybenX因其吸湿特性而变干;因此,它在治疗相关疾病方面有效。本研究旨在评估HybenX在上颌第一前磨牙牙本质小管中的渗透程度。

材料与方法

进行实验干预,评估30颗拔除的上颌前磨牙,使用三种不同的冲洗技术(被动超声冲洗、动态手动冲洗和传统单喷射冲洗技术)来确定HybenX和5%次氯酸钠在牙本质小管中的渗透程度。根管预备后,用荧光罗丹明6G冲洗根管;然后制作500微米厚的切片,在荧光显微镜下进行分析。在ZEN软件中以微米为单位进行测量,以确定每种物质在不同根管三分之一处的渗透程度。

结果

在根尖三分之一处,发现三种冲洗技术之间存在显著差异(<0.05),同样,在根管中部和颈部三分之一处也是如此。使用传统单喷射冲洗和被动超声冲洗技术时,在颈部和中部水平发现HybenX和次氯酸钠之间存在显著统计学差异。至于根尖水平,在被动超声冲洗技术和动态手动冲洗技术之间发现了差异。

结论

基于本研究,HybenX被证明能高度渗透到牙本质小管中,尤其是在使用被动超声冲洗技术时。HybenX可能是牙髓病学中根管冲洗的一个有用选择。
