摘要

这项研究评估了使用超声波探头的三种不同方案去除玻璃纤维桩(GFP)的效果。对 36 颗拔出的单根牙齿进行了根管治疗,并用 10 毫米的 GFP 粘接。拔除 GFP 时使用了三种方案:20 秒冷却激活、20 秒不冷却激活和 40 秒不冷却激活。记录拔除时间和根外表面温度的升高。使用微型计算机断层扫描评估残留材料的数量和牙本质损失的体积。数据采用方差分析,显著性水平为 5%。清除时间和残余材料的数量不受治疗方案的影响。20 秒组之间的温度升高没有差异。未冷却的 40 秒激活组温度最高,尤其是在根尖区域,牙本质损失也更大。连续使用超声插入器超过 20 秒是不可取的。

Fibre post removal using ultrasonic tips: A comparative in vitro study using different protocols.

This study evaluated the glass fibre post (GFP) removal using three different protocols with ultrasonic tips. Thirty-six extracted single-rooted teeth were endodontically treated and cemented with a 10-mm GFP. Three protocols were used for GFP removal: 20 s activated with cooling, 20 s activated without cooling and 40 s activated without cooling. The removal time and temperature increase on the external root surface were recorded. The amount of residual material and the volume of dentin loss were assessed using micro-computed tomography. Data were analysed using ANOVA with a 5% significance level. The removal time and the amount of residual material were not affected by the protocol. There was no difference in temperature increase between the 20-s groups. The 40s activated without cooling produced the highest temperatures, especially in the apical region, and greater dentin loss. It is not advisable to use the ultrasonic insert continuously for more than 20 s.

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.
