This study investigated the prognosis for successful endodontic treatment and the correlation between the size of the periapical lesion, the quality of the root canal treatment, and the type of coronal restoration.
Periapical radiographs of 319 teeth with periapical periodontitis were studied. The area of each lesion was measured before treatment and 1 to 12 years after completion of the endodontic treatment. The measurements were performed using computerized morphometry.
In 65.2% of the teeth, the size of the lesion decreased, while in 34.8% of teeth, there was an increase. Lesions larger than 10 mm2 had a greater tendency for healing.
No significant correlation was found between the quality of root canal treatment, the type of the coronal restoration, and the success rate of the endodontic treatment.
本研究调查了根管治疗成功的预后情况，以及根尖周病变大小、根管治疗质量和冠修复类型之间的相关性。
对319颗患有根尖周炎的牙齿的根尖片进行研究。在治疗前以及根管治疗完成后1至12年测量每个病变的面积。测量采用计算机形态学方法进行。
65.2%的牙齿病变大小减小，而34.8%的牙齿病变大小增加。大于10平方毫米的病变愈合倾向更大。
未发现根管治疗质量、冠修复类型与根管治疗成功率之间存在显著相关性。
