摘要： 目的:用SiO2/Poss复合树脂嵌体和3种临床常见树脂嵌体修复牙体组织,观察边缘微渗漏情况,为临床工作提供选择依据。方法:将32颗离体前磨牙按嵌体备洞原则制备V类洞,随机分为4 组,每组8颗。分别用SiO2/Poss, Z250,Z350,BeautifulⅡ树脂制作嵌体, 冷热循环和品红染色处理后,剖开牙体。体视显微镜观察每组嵌体龈壁和牙合壁的微渗漏最显著部位,测量3次取平均值。结果:SiO2/Poss复合树脂嵌体边缘微渗漏深度最小。结论:SiO2/Poss可以作为临床嵌体材料的选择。

Abstract: Objective: To evaluate the marginal microleakage of SiO2/Poss and the other three kinds of composites. Methods: 32 healthy maxillary premolars were collected and were divided into four groups, and Class V cavity was prepared on each tooth. The cavities were restored by SiO2/Poss, Z350, Z250 and Beautiful Ⅱ composite resin. Then the teeth were cut into half through the middle of the restoration after thermal cycling and dying. The depths of the fuchsin solution penetration on the gingival and occlusal wall of the cavity were observed under the stereomicroscope and then measured. Results: The teeth restored by SiO2/Poss composite showed the least marginal microleakage, while the others showed no difference. Conclusion: SiO2/Poss composite could be a potential material for clinic use.
