This study in vivo evaluated the sensitivity of class 1 and 2 amalgam restorations which had bases of either zinc phosphate or an admix, silver-reinforced glass ionomer. The evaluation of sensitivity was done by providing the patient with five postcard questionnaires to be mailed to the clinic over a period of time from one to 28 days. Teeth restored with amalgam and silver-reinforced glass ionomer were significantly less sensitive to cold than those restored with amalgam and zinc phosphate.
本体内研究评估了一类和二类汞合金修复体的敏感性，这些修复体的基底材料为磷酸锌或一种混合材料——银增强玻璃离子水门汀。敏感性评估通过向患者提供五张明信片调查问卷来进行，患者需在1至28天的时间段内邮寄回诊所。用汞合金和银增强玻璃离子水门汀修复的牙齿对冷刺激的敏感性明显低于用汞合金和磷酸锌修复的牙齿。
