摘要
目的:探讨不同树脂、不同粘结剂、不同光源、不同光照时间、不同光照角度对复合树脂微渗漏的影响。方法:64颗离体磨牙,随机分为32组,每组2颗牙,分别采用不同材料及方法充填牙齿,2%碱性品红染色,体视显微镜下观察微渗漏情况。结果:粘结剂、光源、光照角度3种处理因素自身不同水平比较,差异具有统计学意义(P(0.01),树脂与光照时间之间存在交互作用(P(0.01)。结论:粘结剂、光源、光照角度、树脂和光照时间的交互作用对光固化复合树脂微渗漏有影响。
Objective： To evaluate the effect of different composite resins, different adhesives systems, different light curing units, different irradiation time and different irradiation angles on the mieroleakage of composite resin. Methods： Sixty--four extracted human molars were randomly divided into thirty--two groups. After completing re- storative procedure, specimens were immersed in 2% basic fuchsine dye. Dye penetration was observed under a stereomicroscope, and the depth of the microleage was scored and recorded. Results： The differences of three factors -- adhesives system, light curing unit, irradiation angle, were significant （P〈0.01）, and the effects between-- subjects were involved between the composite resin and light curing unit （P〈0.01）. Conclusion： Microleakage of composite resin may be affected by adhesives system, light curing unit, irradiation angle and the effect between composite resin and irradiation time.
