摘要
目的对比银汞、MTA、Ca(OH)2+GIC修复不同大小髓室底穿孔所导致的牙周根分歧部位牙槽骨吸收的疗效,评价3种材料对牙周组织的炎症反应和硬组织形成的影响。方法选择86例86个髓室底穿孔的磨牙或前磨牙,按穿孔大小分成2组,每组按就诊时间随机分成3组,分别采用MTA、银汞、Ca(OH)2+GIC修复,于3、6、12个月随访观察,拍X线平行投照片,观察病变区临床疗效及牙槽骨恢复情况。结果穿孔直径<2mm,MTA修复成功率100%,银汞成功率75%,Ca(OH)2成功率78%,差异无显著性。直径>2mm,成功率分别为64%,42%,64%,银汞与另两组间差异有显著性意义(P<0.05)。结论 MTA及Ca(OH)2+GIC修复大的髓室底穿孔所导致的牙周根分歧部位牙槽骨吸收的治疗效果显著优于银汞组,是两种很好的骨修复诱导材料。
Objective To compare the effects of Amalgam, MTA, and Ca （OH）2 ＋ GIC for repairing alveolar resorption in furcation of the periodontal root induced by perforation at the pulp bottom, and to evaluate the effects of the 3 kinds of material on inflammation response and hard tissue formation. Methods Eighty-six patients with 86 molar or premolar teeth with the perforation at the pulp bottom were selected. According to the size of the perforation, they were divided into 2 groups. Each group was then divided into 3 groups randomly according to the time in clinic, in which MTA, Amalgam, or Ca（ OH）2 ＋ GIC was used for repairing. X-ray film was used to observe the efficacy at the sites and bone recovery on 3-, 6-, and 12-month after the treatment. Results The successful repairing rate in perforation size less than 2ram in diameter was 100% with MTA, 75% with Amalgam, and 78% with Ca（OH）2, respectively. The difference was not significant. In perforation size larger than 2mm in diameter, it was 64% , 42% , and 64% , respectively. The differences between Amalgam group and the other 2 groups were significant. Conclusion MTA or Ca （OH）2 ＋ GIC is superior to Amalgam for repairing alveolar resorption in furcation of the periodontal root induced by perforation at the pulp bottom. They are good materials for bone repairing.
