Healing capacity after apicectomy was investigated in a randomized clinical study of 105 teeth apically sealed with either amalgam or glass ionomer cement. The results were evaluated clinically and radiographically after 1 year. The success rate was high for both materials: 91% for amalgam and 89% for glass ionomer cement. Contamination with moisture and blood adversely affected the outcome for both materials and was significantly more frequent in unsuccessful cases.
在一项针对105颗分别用汞合金或玻璃离子水门汀进行根尖封闭的牙齿的随机临床研究中，对根尖切除术的愈合能力进行了调查。1年后，对结果进行了临床和影像学评估。两种材料的成功率都很高：汞合金为91%，玻璃离子水门汀为89%。水分和血液污染对两种材料的结果都有不利影响，并且在失败病例中明显更常见。
