The purpose of this study was to establish the midterm prognosis of periapical surgery by use of the ultrasound technique, comparing a scale obtained by image analysis with the success rates according to other prognostic scales.
A clinical follow-up study was performed between September 2004 and September 2005. Thirty-six patients with chronic periapical lesions were treated with periapical surgery via the ultrasound technique and root-end filling with silver amalgam. Evolution was analyzed by use of the different currently accepted assessment scales at 6 and 12 months after intervention with a scale obtained by radiographic image analysis.
Thirty patients with a mean age of 40.5 years were studied. The mean follow-up period was 14.2 months. Thirty-seven lesions were analyzed. A positive correlation at 6 months was observed between the radiographic scale proposed in this study and the scales of Rud and Andreasen and von Arx et al. At 12 months, the proposed radiographic scale only correlated with the functional tooth concept established by Friedman.
There was no statistically significant relation between the radiographic scale from the image analyzer and the criteria of Rud and Andreasen and von Arx et al.
本研究的目的是通过使用超声技术确定根尖手术的中期预后，将通过图像分析获得的评分与根据其他预后评分得出的成功率进行比较。
在2004年9月至2005年9月期间进行了一项临床随访研究。36例慢性根尖周病变患者通过超声技术进行根尖手术并用银汞合金进行根充。在干预后6个月和12个月时，使用不同的目前公认的评估量表以及通过影像学图像分析获得的量表对病情进展进行分析。
研究了30例平均年龄为40.5岁的患者。平均随访期为14.2个月。分析了37个病变。在本研究提出的影像学量表与Rud和Andreasen以及von Arx等人的量表之间，在6个月时观察到正相关。在12个月时，提出的影像学量表仅与Friedman建立的功能牙概念相关。
图像分析仪的影像学量表与Rud和Andreasen以及von Arx等人的标准之间无统计学上的显著关系。
