Abstract

This study aimed to compare apical debris extrusion and canal preparation time with ProTaper Gold (PTG) and ProTaper Ultimate (PTU) files at different temperatures. Mesio-buccal roots of 60 mandibular first molars were distributed into six groups depending on the file type (PTG, PTU) and irrigation solution temperature (20, 37, 45°C). During instrumentation, extruded debris were collected and weighed to measure the mass in milligrams. The canal preparation time was recorded in seconds. ANOVA followed by Bonferroni post-hoc tests were used for analysis. The amount of debris extrusion was significantly higher in PTU, which was affected by the irrigation solution temperature (p < 0.05). The difference in canal preparation time was not significant between the two file systems, however, it was significant between the different temperatures (p = 0.001). Both file systems had shorter canal preparation times at 20°C. The irrigation solution temperature could influence the debris extrusion and time of canal preparation.

冲洗溶液温度和新型热处理旋转锉对根尖碎屑挤出和根管预备时间的影响

本研究旨在比较在不同温度下使用ProTaper Gold（PTG）和ProTaper Ultimate（PTU）锉进行根尖碎屑挤出和根管预备所需的时间。根据锉的类型（PTG、PTU）和灌洗液的温度（20、37、45°C），60颗下颌第一磨牙的中颊根被分为六组。在器械操作过程中，收集挤出的碎屑并称重，以毫克为单位测量其质量。以秒为单位记录牙道预备时间。采用方差分析，然后进行Bonferroni事后检验。在 PTU 中，挤出的残渣量明显较多，这受到灌洗液温度的影响（p

期刊介绍： The Australian Endodontic Journal provides a forum for communication in the different fields that encompass endodontics for all specialists and dentists with an interest in the morphology, physiology, and pathology of the human tooth, in particular the dental pulp, root and peri-radicular tissues. The Journal features regular clinical updates, research reports and case reports from authors worldwide, and also publishes meeting abstracts, society news and historical endodontic glimpses. The Australian Endodontic Journal is a publication for dentists in general and specialist practice devoted solely to endodontics. It aims to promote communication in the different fields that encompass endodontics for those dentists who have a special interest in endodontics.
