BACKGROUND
The endodontic space is complex, and using a single-cone obturation technique fails to ensure a complete filling.
INTRODUCTION
This study aimed to investigate the effect of ultrasonic activation, sonic activation, and single-cone technique of a biosealer on its dentinal tubular penetration.
MATERIALS AND METHODS
In the experiment, single-root mandibular premolars were randomly assigned to three groups ( = 20): group A, ultrasonic activation; Group B, sonic activation; and Group C, single-cone technique. Penetration of the fluorescently labeled biosealer was investigated using a confocal laser scanning microscope.
RESULTS
The data were statistically analyzed using Kruskal-Wallis and Mann-Whitney tests ( = 0.05). The highest penetration of biosealer was observed in Group A, followed by Group B ( < 0.05).
CONCLUSIONS
Dentinal tubule penetration of biosealer was significantly improved by ultrasonic and sonic activation techniques.
背景
根管系统复杂，采用单锥充填技术无法确保完全充填。
引言
本研究旨在探讨超声激活、声波激活以及生物封闭剂单锥技术对其牙本质小管渗透的影响。
材料与方法
在实验中，将单根下颌前磨牙随机分为三组（每组n = 20）：A组，超声激活；B组，声波激活；C组，单锥技术。使用共聚焦激光扫描显微镜研究荧光标记生物封闭剂的渗透情况。
结果
采用Kruskal-Wallis和Mann-Whitney检验对数据进行统计学分析（α = 0.05）。A组生物封闭剂的渗透最高，其次是B组（P < 0.05）。
结论
超声和声波激活技术显著提高了生物封闭剂的牙本质小管渗透率。
