Abstract

This study assessed the usability of ultrasonography in detecting root canal perforations. The buccal side of incisor root were perforated. The actual lengths up to the perforation site were measured by visualisation of the tip of a file. Specimens were embedded in gypsum, and it was scraped to simulate bone resorption. Resorption cavities were filled with ultrasound gel. Measurements were taken by advancing a file through the canal until the tip became visible in the ultrasound image. 3D scans were obtained using cone-beam computed tomography (CBCT) and the distance between the coronal point of the resorption cavity and the reference point was measured. The actual distance of the resorption cavity from the reference point varied 6-10.6 mm. The same distances were measured via ultrasound as 5.7-10.9 mm, while measured using CBCT 6-10.5 mm. No significant differences were found. Ultrasonography shows promise for detecting root perforations, however further research is needed.

超声波能用来检测牙根穿孔吗?一项体外研究。
本研究评估了超声波成像在检测根管穿孔方面的可用性。对门牙牙根的颊侧进行穿孔。通过锉刀尖端的可视化测量穿孔部位的实际长度。将标本嵌入石膏中,并刮除石膏以模拟骨吸收。用超声凝胶填充吸收腔。测量方法是将锉刀穿过牙槽骨,直到在超声波图像中看到锉刀尖端。使用锥束计算机断层扫描(CBCT)获得三维扫描图像,并测量吸收腔冠状点与参考点之间的距离。吸收腔与参考点的实际距离为 6-10.6 毫米。通过超声波测量的距离为 5.7-10.9 毫米,而使用 CBCT 测量的距离为 6-10.5 毫米。没有发现明显差异。超声波检查在检测牙根穿孔方面大有可为,但仍需进一步研究。

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.
