不同箍结构对纤维桩核修复冠方微渗漏的影响
|
摘要
目的:研究不同形态的箍结构对纤维桩核修复冠方微渗漏的影响。方法:选择因正畸治疗需要而拔除的下颌单根管前磨牙50颗,随机分成5个组:完整箍结构组(第1组)、1面缺损的箍结构组(第2组)、2面缺损的箍结构组(第3组)、3面缺损的箍结构组(第4组)以及无箍结构组(第5组)。所有标本经纤维桩核修复后模拟口内老化情况,并经染色处理,在体式显微镜下记录各组微渗漏的情况。结果:第1组的微渗漏情况最轻,第5组的微渗漏情况最重。第1、2、3组之间微渗漏情况无统计学差异(P>0.05),第2、3组和第4组之间微渗漏情况均无统计学差异(P>0.05)。但第1组和第4、5组间微渗漏差异有统计学意义(P<0.05),第2、3组和第5组间微渗漏差异有统计学意义(P<0.05)。结论:牙体修复时至少应保留一面牙本质肩领,即使在没有完整箍结构的情况下也能获得良好的修复效果。
Objective: To study coronal microleakage of different ferrule forms of the fiber post and core restoration. Methods: 50 mandibular premolars were divided into 5 groups: completeferrule group(Group 1), one surface defect of ferrule group(Group 2), two surface defects of ferrule group(Group 3), three surface defects of ferrule group(Group 4), without ferrule group(Group 5). All teeth were repaired with fiber posts, and dyed. The teeth were observed under stereoscopic microscope and the dyeing scores were also recorded. Results: The microleakage of Group 1 was the lightest while that of Group 5 was the most serious. The microleakage of Group1, 2 and 3 showed no statistical difference(P>0.05). The microleakage of Group 2, 3 and 4 showed no statistical difference(P>0.05). But the microleakage of Group 1, 4 and 5 were statistically significant(P<0.05). The microleakage of Group 2, 3 and 5 were statistically significant(P<0.05). Conclusion: Retention of at least one surface of ferrule is preferred even in case of incomplete ferrule, which enables it to achieve good repair effect.
